flat-free tires

 2022.7.2: web.gear/bike/flat-free tires:

. solid tires are slower with

a much higher resistance to rolling

because they don't conform to bumps,

but I have felt such a sense of security

knowing that my commute to work 

will not be slowed by a flat repair,

which can get messy and complicated,

not sure to succeed.


I've gotten a lot of mileage out of amerityre

https://amerityre.com/our-flat-free-products/flat-free-bicycle-tires/

but they have made some design changes

since the tires I've tried.

. a folding bike I'm considering

comes with:

. another great choice is Tannus.

filling tires with air is easier with a Topeak adapter

2021.9.10: summary:

https://amzn.to/3C4tMu6

. this adapter makes it easier to 

get a pump on the tire's valve,

if you have big tires 

and pressing the pump onto the valve

tends to push the valve into the tire.

. if locking the pump onto the valve

takes a lot of power, this adapter 

gives you more room away from the spokes.

idiot-proofed derailleurs

[1.10:
. this idea might actually be worth it for a velomobile,
where stalling on a forgotten downshift
can represent a non-trivial traffic impediment
due to the velo' being wider than your ordinary bike
and not easily push-started .]

4.23(2009): tech.gear/mobi/derailleur changing while still:
. did anyone try a front derailer on the underside,
one that would change gears by pedaling backwards?
. that idea would work for the rear derailer too,
but there are so many of those to do,
pedaling backwards would be an annoyance .
. these would be great for when being
caught by surprise in high gear,
and then no longer would you have to find some manual way
of getting started before you can downshift .

. with tires there is the issue of size:
balloon tires might provide suspension
that protects the frame;
or trice may come with rims that fit
only the tires it lists ?
. my intuition was right about being
. when ice says they have a 20" 406,
the 406 is the bead dia' .
. 406 and 451 are the two most common
bead diameters on 20" tyres.
. The one dimension that is really critical
is bead seat diameter
(which is what the first number
- on the ETRTO size refers to)
this is the bit inside the rim
where the tyre sits -
the rim above that can varying a bit without problem.
. check the tyre for an ISO number .
. their tire make mentioned that
some customers don't match rim to tire correctly?
does trice give you too much freedom?

Degreasing the chain isn't a lot of work. Simply pop out the power link and drop the chain is a plastic juice container with a couple of ounces of citrus degreaser and shake it for a minute and rinse... done! You can chase the water out of the inside pieces by baking in the sun or baking in the oven or dunking in acetone. I haven't replaced the cassette because it performs flawlessly. Lubing an uncleaned chain chases dirt form the outside of the chain where it is doing little harm to the inside where it causes a lot of wear.

Actually what I did was put around 3,500 miles on 3 chains and then I went back to the first chain and an am now starting on the second 3,500 miles on each chain. Makes good sense if you think about it.

6.30: chain cleaner:
Best chain cleaner I found is diesel. Put an ice cream tub under the chain at the rear section, use a brush to brush it well in and rub with an old rag to remove. I do this monthly.
Remove and soak the whole chain overnight, I do this a couple of times in winter.
Remember to use snap on links for 9 speed chain.
I use a motorbike chain lube spray to re-lube.
The used diesel if allowed to stand a few days can be drained off and used again
wear gloves,

Another good cleaner is Green oil
They manufacture: Chain Cleaner, Frame cleaner, grease and oil.
To clean chain simply cote it with chain cleaner ride around for a few minutes and wash it off!
To clean frame either buy the frame cleaner and apply and wash,
or dilute one can of chain cleaner in a litre (that's 1.76 pints in Anglo saxon)of water and use it as normal. Uk stockist is Chain Reaction Cycles.
See Ctc website for advice on dismantling and reassembling 9 and 10 speed chains!
Basically these chains must be joined with the special link
as supplied by ICE or they will break whilst in use.
Have fun Regards. Ted.


8.6: co.trike/maint/[triceriders] I hate GOAT HEADS:
date Wed, Aug 5, 2009 at 10:10 PM
You need some sort of protection for goat heads--period.
I automatically install True Goo in all trikes intended for regional use
and I have always used it in my personal trikes.
You can use a thick tire liner like Tuffy.
Of course Marathon Plus takes care of the problem
and, in a 1.75 size, rides well too.
Big Apples may ride well but have no postive effect on the thorn issue.
My rule when using Goo is to pump twice if a tire goes down
(after removing broken off thorns).
If it goes down a third time, -- only twice in six years on the trail,
then install your spare tube
and patch the failed Goo-filled tube at home before reinstalling it.
Chip, recumbenttrikestore.com
date Thu, Aug 6, 2009 at 8:58 AM subject [triceriders] Re: Goo and Shipping:
Here's an interesting issue we found out about Goo.
We shipped our trikes (3 days, Fed Ex) with the tires deflated.
When we inflated the tires while re-assembling the trikes,
each of us had one tire with two holes in it that needed patching.
Evidently the Goo had been doing it's job blocking up the holes
and then the hole re-opened as it was shipped.
8.8: bk:

. hub `sealed (precision) bearings?
they require less service, but service is more costly .
. trice`bottom bracket likely has sealed bearings
and never needs service (low rpm = low wear)?

. bottom bracket uses an adjustable left cup;
it needs special splined tools .

. pedal-mashing can create chain ring flex;

The Freebhub Buddy allows you to inject clean grease
into Shimano Freehub bodies, displacing dirt and old lubricants.
Thick grease may cause problems if used in very cold weather.

. chain links are 1",

. beware veg-based oils like 3-in-1 .

8.9: bk:

. indexed deraileur controls depend on precise hanger shape

. kerosene, paint thinner or diesel fuel (adds oil),
are good solvents for thick grease grimes
-- jobs that don't clean up with dish soap
meant for light oil and particulate messes .
[ParkTools insist you use their orange chain cleaner for that]
. lube can come from auto supply:
for bearings and cables use white lithium grease,
for lighter oil jobs use 30wt motor oil .

8.11: bk:

. another reason for shimmy at high speed is rider weighs a lot on

. imron urethane paint .

You should never spray your paint directly on the bare metal.
A primer will help adhesion of the paint to the metal surface.
Should you be painting over an existing painted surface,
a "sealer" should be used to ensure that there is no
bleed of the old paint into the new paint.
As an added note, you should never try to paint lacquer over an noncatalyzed enamel
[some other source:]
. Imron; This was popular years ago.
I would have to describe it as a rubber based polyurethane.
It was originally designed for airplanes that are subjected to extreme temperature changes
. It then was used on fleet trucks.
The stuff does not chip. Brake fluid will not damage it.
If you get a run, you can't sand it out!
This stuff is so toxic that when I sprayed it, I breathed off of a scuba tank!
You have to clean out your gun when done, or throw the gun away.
The left-over paint will bounce like a ball.

too low will cause some shimmy.
date Sat, Aug 15, 2009 at 9:35 AM
Hi, most times I've had shimmy is due to
the headsets on each wheel coming loose.
This happens quite often when new.
If you can get hold of some old school steel locking washers
with a corrugated under surface,
these seem to hold better than the thin alloy ones.
I also locked the threads with Loctite 243.
After a year I also found that the big nuts holding the front wheels
had become loose.
The front tyres should always have the same pressure of air in them.
Check all these things,
trikes cause a lot of vibrations to all moveable parts .

. the shimmy on his 20" Q is now cured.
there was an o ring missing in the headset.
It might be worth checking your headset against an exploded drawing?
8.16:
. same problem developed on my new QNT after only a few days.
I tried to checked the alignment,
retorque everything I could think of,
and checking tire pressure.
It improved a lot but
there is still a bit of shimmy at high speed.
So I find that headset thing interesting.
The manual says:
"After the first 50 or 100 miles,
check the steering components for signs of looseness.
The headset bearings may need to be snugged up
after they have bedded in,
and the axles should be checked for tightness as well".

. ICE has been shipping (the last three trikes)
with a well greased O ring between the steering pin cap and first bearing.
.. for those who would like to try
adding damping to the steering,
one could insert--stretch and snap like a rubber band--
an O ring in this location.
The supplied ring has 1/8" thickness and 7/8" id with 1 1/8" od.
It is greased when installed.
The effect is a pressure fit between the cap and stem
which gives the steering some resistance.

It was introduced to offset any excess steering vibration

Joe, During my 7,000 miles on my Q
I didn't remove both hands at any speed above 10 mph
that I can remember.
However, I know that in breaking the two frames in,
at about 400-800 miles
the steering and tracking changed and the fix was:
tightening the loose headsets.
I am tempted to loosen the headsets as see if I can create this shimmy.
What is missing here is a root cause analysis.
Are the o-rings placed to
lessen the inevitible initial set in of the headsets?
The same retightening of the main steering bolt
was experienced in both frames.
I observed both times that removing the bolt revealed
a crushed ring of frame paint under the lower bearing,
when the crushed ring of paint was removed
and the bolt retightened,
eliminated the need for further retightening.
I have since been on some really rough macadum
and the steering is solid.
After the onetime tightening, retightening was not required.

8.20:
date Wed, Aug 19, 2009 at 8:07 PM
Shimmy of this sort was once a very common problem in automobiles
of the 1920s and 1930s when most cars had solid front axles.
The axle would oscillate whenever its equilibrium was disturbed.
The addition of front brakes in the late 20s made it worse
by increasing the amount of weight on the ends of the axle.
It was the main reason for the widespread adoption of
independent front suspension during the 1930s.
My Model A Fords would develop it when their front radius rod attachments
(which kept the front axle in position) became loose.

It would happen much as described on a Trice,
when the front wheels would hit a bump simultaneously
(such as a ridge across the road) when going fast enough;
it would stop if I hit the brakes
and slowed down below the critical speed.

It is also endemic on Morgan cars,
which have independent front suspension,
but very hard springs
and practically no suspension travel.
I have previously remarked on the resemblance between
a recumbent tadpole trike
and a Morgan three-wheeler.
The crosshead of a Morgan behaves very similarly
to the cross-arm of a trike,
which similarly pivots around
its attachment at the centre
and relies mainly on frame flex for suspension.

On a Morgan, the frame flex absorbs more bumps
than the springs do (I can lean my full weight
on the front of my Morgan without compressing the springs).
On my 1970 four-wheeled Morgan
(which has the same suspension as the three-wheeler),
it happens right around 55 mph if it is going to happen at all.

The cure for shimmy on Morgans
is the same as on a Trice:
first make sure than everything is
tight and properly adjusted
(a 5 psi difference between front tire pressures
can cause Morgan shimmy,
as can wheel balance, kingpin wear,
and apparently the phase of the moon
) and then
introduce some friction into the system to dampen it.
My 1927 Morgan Aero has on it
a "Hooley Steering Damper"
that simply acts like the O-ring in a Trice headset.

In addition, as mentioned,
the rear end adjustment
(tire pressure, and boom length on a Trice)
can affect the front's tendency to shimmy.

8.23: try the o-ring. [reinstalling what Chip uninstalls]
rgammelg@gmail.com
date Sun, Aug 23, 2009 at 9:09 AM
I started experiencing some changes in the steering
after about 300 miles of riding.
I checked the tire pressure and alignment.
Then I tightened the headsets and noticed a slight improvement.
I emailed Chip and he suggested that I
try the o-ring. [reinstalling what Chip uninstalls]
I just inserted it yesterday
and did notice some differences.
Even with proper tire inflation
my wheels would start to oscillate back and forth
and continue to exaggerate
until I had to put my hands on the steering.
Now, with the o-ring inserted,
I am able to ride with no hands and any speed.
Prior to the o-ring,
I would occasionally notice a slight pedal steer effect.
Now that also appears to have been dampened.
It was fairly easy to install.
Just loosen the two bolts on the side of the stem
(where the handlebars pivot)
and lower the stem.
Grease and apply the o-ring over the bolt
and above the top bearing.
Pull up on the stem until it is back in the original position
and tighten the stem.

8.17: co.mobi/trike/maint/trice maintenance tools and tips:

. for those who do their own maintenance,
and have had a chance to do all the tasks;
did you find any surprises, have any favorite tools,
or favorite places to get parts and tools ?
. the first tool I'm wondering about
is a torque wrench for the pedal wrench .
. trice warns about following these instructions exactly
-- that would include a torque wrench
which involves either much cost or comments like "(ineffective) .
. are all the bearings sealed?
where do you get replacements ?
. what are the spec's on the trice cassette lock rings

[. not sent, search instead:]

torque wrench talk: (Kerry Irons)
The only thing I use the torque wrench for
is BB's and cassette lock rings.
I'm very comforable with doing everything else free hand,
but I find that [doing it free-hand] will likely not get
70 n-m torque for a BB.
The beam units are not nearly as accurate or reliable.
With the "clicker" system, you don't over-torque.

. our current favorite is this very easy to use split-beam type
by Precision Instruments [C2 Split Beam]
It's important to note that
figures regarding torque wrench accuracy
are usually valid from 20% up to full
of the full scale of the wrench's rated torque capacity
Micrometer torque wrenches can be very accurate;
some are rated at ±3% accuracy
(i.e., about ±1 ft. lb. at a 30 ft. lb. setting).
they can be used in both a clockwise and anti-clockwise direction
(although torque wrenches should never be used to release a fastener).

chain selection and sources:
8.19: co.mobi/triceriders@yahoogroups.com/trike

. what chains feature the most reusable master links,
vs links that must be broken apart or are very difficult ?

. do any of you in {usa, uk, euro} buy chains by mail-order?

. books disagree on solvents:
why should I use the ParkTools` orange cleaner instead of, say,

. Bicycle Mag's book tries to economize by using
the same stuff provided by the auto industry .

other hints by that book:

good solvents for thick grease grimes:
. kerosene, paint thinner or diesel fuel (adds oil),
-- jobs that don't clean up with dish soap
which is meant for light oil and particulate messes .

good lube:
. for bearings and cables use white lithium grease .

Sram chains have what they call a power link.
I've never had on fail on me. -

I suggest using a single chain without the expensive links.
Power-On-Cycling, for example, carries SRAM 951 9 speed chain,
Good all around 9 speed chain.
The choice of manufacturers on their higher end bikes.
PC-951 has gray outer plates.
PC-971 and
PC-991 have silver outer plates.
Each box includes 114 links and a power link.
Most recumbents will take 2 to 3 boxes to make a complete chain
-- SRAM made some minor tweaks to the PC-971 to
enhance shifting performance with Truvativ chainrings
while continuing to offer accurate shifting in SRAM or Shimano drivetrains.
Nickel-plated outer plates for durability with grey inner plates.
Gold PowerLink master link included.
[but one on amazon said it didn't work so well with shimano]
cut to length, one piece.
Add postage and it will be less than DF shots of chain.
Add say 6" for fitting to your needs.
Besides bulk chain will prove to be a discount to you
as the dealer buys it by the 1000 ft roll.
Carry those quick links for emergencies on the road.

If you are the [lube it on the bike] type
a ten foot chain isn't a problem
but if you want to maximize the life of your drivetrain
you would do well to take the advice of Sir Sheldon and Jobst Brandt.
Never apply lube to a dirty chain.
The dirt on the outside is doing very little harm
but when you apply lube
it is carried into the inner parts where it forms
the equivalent a grinding paste. This kills chains.
Every 200 miles take it apart
and shake it in a container containing citrus degreaser
then rinse well and dry in the sun or oven.
You can expect at least 6000 miles out of a chain,
and if you rotate 3 chains
you can expect at least 20,000 miles
out of your cassette and chainrings.

8.30: my response:
. follow up on leads .
. what is power link vs quick links?
web:
. here's a story of trouble with power link .

. Park Tools makes a special set of pliers (tool #MLP-1) $15-$17,
that works great on any master link.
Simply insert the specially sized jaws into the masterlink
and squeeze the handles, while pinching the sides of chain .
You need to squeeze the plates together,
but if you squeeze them too hard, they will bind against the rollers
and the pins won't want to move toward each other.
. to make this tool yourself,
bend a piece of stiff wire(old spoke) into a Squared off "U"
[then any pliers can press on the wires to press on the links]
. precede with slight WD-40 flush .
else
take a pair of pliers and set them in the wide position,
then "Z" the chain so the link is the "/" of the "Z"
You can now push the opposing plates
with the pliers angled so each jaw only touches the outer plate.
another success with Z:
Grab the links on either side of the power link
and push together until the powerlink is 90¡ to the chain.
Pinch the side plates of the powerlink with one hand
and push one of the adjacent links to slide the powerlink.

[wire bent to form pliers with hooked jaws
that can hold chain ends together ]

Taking the tension off the piece of chain you're working on
makes removing a rivet or a PowerLink much easier.

. use a chain tool to push the powerlink pins just a hair farther out.
Removal takes a matter of seconds.
I have done this to countless powerlinks for years with zero failures.

prevention: [I tried this]
. before you install the link,
fiddle with it off the chain a little
to figure out the double action.
Then try it on the chain while not on the bike.
Then go for the full installation.

" I remove my gold powerlink
at least once a week for chain cleaning
" The SRAM links cooperate with me
but the KMC links don't.
" Money saved on KMC/Nashbar chains went towards a Park tool.
" I have found that the silver Powerlink
is MUCH more difficult to open when new
than the *gold* powerlink that comes on narrower (9-speed) chains.

I'm willing to bet being a former bicycle mechanic
(and still doing work on the side)
that the chains are not being installed properly
with the Shimano replacement pins.
The replacement pins are a PITA[pain]
but a very simple remedy is a SRAM Powerlink or Connex Connector...
both of which I have used with success
on this chain (I've used two now).
The chain has been reliable, smooth shifting,
and long term durability has been on par with
others at or above its price range.
Having broke both PC69 (now the PG971) SRAM chains in less than a year...
I would highly recommend it over that chain.
I've run HG93 and CN 7701 chains in the past
and I am pleasantly surprised at the quality of this chain.

. threads should be oiled; large threads should be greased;

8.21: mobi/trike/prep like short trips could get long:
. on even short trips, take plenty of water
since being chased by a dog turn it into a long trip .

8.20: co.mobi/trike/trice/maint/tire sizing:
. tyre manufacturers have cleaned up their act a lot in recent years.
In addition to the old 'nominal OD' marking,
which can be hugely misleading,
nearly all modern tyres also carry ISO size markings.
EG 40-406 for a nominally 20-inch Marathon Racer
or 35-406 for a Kojak.
The second number is a direct measurement of the bead seat diameter
(as per cars as stated above
Bike tires are sized by the nominal outside diameter,
not like car tires which are sized by the diameter of the inside of the bead
(where they seat on the wheel).
They often are not the size they are marked. )
while the first denotes the width of the tyre.
The width figure may not be 100% accurate in every case
as it can be affected in a minor way by the width of the rim it is fitted to,
but it is a whole order of magnitude more accurate than the old nominal system.
Using the marked ISO numbers as a basis,
and taking the width marking as height,
normally yields an accurate enough result
for setting a cycle computer.

The ISO sizes are a more reliable guide to what tire will fit your wheel
(there often being several different incompatible sizes
called by the same inch designation),
but not necessarily to the actual size of the tire.
and why companies misrepresent the sizes of their tires,

Schwalbe does seem to be fairly accurate.
A 20 inch Marathon Racer is 40-406, giving a radius of 24.3cm.
Assuming the ISO figures to be correct (they are normally pretty close)


. car takes left turn into on-coming traffic
-- almost half of all bike-car crashes,

. cyclist hits an opening car door .
. car exits a driveway into the path of cyclist.

. car turns right without first being in right lane
cutting off the cyclist who is the right lane .

. car hits a slower cyclist from behind .
[
. the chances of this are proportional to
the difference in speed;
if a car is drifting into your lane,
a fast-moving cyclist can counter-drift into another lane .
. then again, speed kills anyway,
as sometimes the reason for the drift
is because the driver has been startled by something falling
reflexively attempting to retrieve it,
and creating a jerk in the steering wheel at high speed .
. this may be difficult to avoid
-- best to stay on low-speed roads .
9.4:
. then again,
a significant number of traffic deaths
are within a few miles of the victim's own home
-- too short a distance to put on their seatbelts,

-- sometimes from crazed drunks that mean to hit you!

43,000 are killed in usa crashes every year,
including 5,000 pedestrians
and 700 cyclists per year.
In other countries,
they've been more active about taking those words seriously.

The United States has the highest
traffic-death rate (15 per 100,000 residents)
of all developed democratic countries.
Several European nations over the past few decades,
- Austria, Belgium, France, Germany,
the Netherlands and Switzerland -
have slashed their annual traffic-fatality figures
largely through "traffic-calming" measures
that forcibly reduce the speeds of motor vehicles.
In places such as Germany and the Netherlands,
traffic regulations are actually biased in favor of
cyclists and pedestrians
-in the event of a bike-car collision,
the legal burden is on motorists
to prove that they weren't at fault,
and Dutch drivers are financially liable
even if cyclists are at fault.
(in the Netherlands,
almost half of all local travel is done by bicycle) .
Dutch and German children are schooled in
safe cycling practices
and, when they grow older and learn to drive,
are taught how to avoid even collisions caused by
lawbreaking cyclists.

that cars hit pedestrians and pedal-cyclists less

and have removed all the tubes except for
a 6 inch piece that protects my right calf.
This short piece is anchored by a couple of wire ties.
I went with this arrangement because, last winter,
The tubes filled with frozen road slush
and the chain would bind so badly
that it was difficult to peddle forward
and I couldn't back peddle at all.

. I read some also degrease the chain
and soak it in hot paraffin .
joe`reply:
I personally, prefer either Pro Link, or Bosheld T9.
I'm sure that there are many good lubes out there.
These are the two I've had the best experience with.
my response:
web for spelling: ProLink Chain Lube
. will not let dirt and grit stick to your chain
-- in wet or dry conditions. It greatly reduces friction and wear,
allowing smoother operation of your chain and cables,
and it will keep your chain and drive train area clean and seemingly drag free.
ProLink is a thin-bodied lubricant that uses MFR technology,
a molecule which bonds to the metal surface.
It does not build up or become tacky
because it contains no solids like Teflon, wax, moly, graphite or plastic.
as a corrosion inhibitor for aircraft components.
safe on paint, plastics, and vinyl.
Boeshield T-9 is a combination of solvents, lubricants and waxes
designed for penetration, moisture displacement, lubrication, and protection.
Boeshield T-9 dries to a thin waxy film that clings to metal.
Because it adheres to metal so well,
it works directly on exposed metal surfaces.
The product can be used in two ways to prevent rust.
A thicker coating works in places where additional protection is helpful
such as on hinges, chains, undercarriages, cables and on items put into storage.

Most of the contaminants on a chain are thrown up by the front tire.
This lands on the outer side of the chain.
For this reason, you should always oil a chain on the inner side,
the side that faces the sprockets.
The best way to apply the oil is with a drip-type oil can,
along the top of the lower run of the chain.
This applies the oil to the cleanest part of the chain.

9.27: co.trice/maint/tire pressure:
The damping has to come from the suspension.
Trice suspension is wonderful compared with nothing
but has a weakness in this regard.

I believe there is danger about
using the linked bicycle chart for three wheeled trikes.
Bicycles do not have side forces on their tires.
The Trice Q has a fairly even weight distribution on each wheel.
My total weight of 240 lbs/3 =80 lbs/wheel...
The article would suggest 35 psi for a 406x35 Kojak.
This is way under the recommended tire pressure by Schwalbe of 55 to 95 psi.
One would run the dangerous risk of a tire rolling off the rim in a tight corner
with only 35 psi in your tires.
Consider you may be in a tight cornering situation on "two wheels".

Schwalbe's tech rep recommended 95 psi for the front Kojaks on my ride.
I have been saved several times in near rollover cornering situations
including one on very rough macadam at over 30 mph.

Schwalbe: "actual tire pressures should never be higher or lower than
the maximum and minimum inflation pressures marked on the tire sidewall."
