in these instructions. SWR FULL CARBON rims are ready to go at
this point and require no further preparation. Traditional aluminum
rims may be lightly sanded then cleaned again with solvent.
• When installing a tire on a previously glued rim, you can usually
just apply a single thin uniform layer of new glue to the rim and tire.
After 15 minutes or when the glue becomes tacky, mount the tire
according to the method outlined in this article.
• Bad glue or a large build up of lumpy glue can be scraped off
using a solvent to soften the old glue. (Alcohol, acetone, or a latex
paint remover such as “Goof-off” is some suggestions. All are avai-
lable at hardware stores.) The SWR FULL CARBON rim can be
cleaned with any solvent that will not harm epoxy.
Glue the rim and tire
• First coat the rim by putting a thin uniform layer of glue on the tire
seating area of the rim. Thin coats of glue work better then thicker
ones. To apply the glue, lay a bead of the cement around the center
of the tire seat area of the rim, skipping over the spoke holes if pos
-
sible. Use the plastic bag over your finger or acid brush to spread
the glue evenly from edge to edge of the tire seating area all around
the rim. Avoid getting glue into the spoke holes as much as possi
-
ble. Set the rim aside for a couple of hours to let the glue dry.
• Most tires will turn inside when inflated off of a rim. Inflate the tire
until it turns inside out then place the tire on a flat surface to apply
a layer of glue.
• An alternate method is to find a way of hanging the tire so that it
can be rotated as glue is applied. A piece of wood clamped to the
edge of a table or workbench works fine. This is optional, but help
-
ful. Blowing the tire up a bit so it holds its shape is also helpful.
• Spread a bead of glue onto the center of the tire base tape. If
using the tire hanging method, hold the tire by one end out parallel
to the ground, coat the half with the base tape facing up, flip and
repeat.
• Use the plastic bag on your finger or acid brush to spread the
glue evenly across the base tape. Set the tire aside for a couple
of hours to dry.
• Clean up any glue drips around the area with solvent.
• After a couple of hours, re-coat both the rim and tire with a se
-
cond thin layer of glue using the same procedure as before.
• Let the second layer dry overnight or for several hours until it dry
to the touch and only slightly tacky.
• After the glue on the rim and tire is dried, apply another thin layer
to the rim only and let it dry about 15 minutes.
Mounting the tire
• Deflate the tire and mount it on the rim as described previously.
Make sure to push firmly down on the area around the valve before
beginning to stretch the tire over the rim. It will be easier to finish
rolling the last bit of the tire onto the rim if you begin with a quite
firm pressure from the very beginning of the mounting process.
Take care that the tire is centered and that an even amount of base
tape is sticking out on both sides around the rim. At this point you
can still move the tire around the rim a bit by tugging and pushing
it into place.
• Pump up the tire to around 80psi. Spin the wheel while looking
for wobbles or twists in the tire. An even amount of base tape
should be visible on either side of the wheel. You may find that the
tread moves back and forth as the wheel spins or that the tire is off
center. Deflate the tire and push or twist it over where required. Re-
inflate and check again repeating the process as needed.
• Carefully clean any excess of glue on the rim sidewall with sol
-
vent. Keep the solvent away from tire!
• Pump up the tire to 120 - 130psi and let set over night to bond
firmly.
• Check the tire pressure before each ride. Check the glue bond
occasionally. Remove and re-glue the tire as needed, or at least
once a season.
ATTENTION:
If at any point whilst fitting the tubular tyres to your Miche wheels
you have any doubt as to how the tubular tyre has been fitted ple

ase consult a qualified cycle mechanic. The fitment of tubular tyres
to Miche wheels is a specialist skill. Incorrect fitting of tubular tyres
to Miche wheels could lead to wheel failure and resulting serious
or fatal accident.
Changing a flat tubular
• Before riding, stretch and pre-glue a spare tire as outlined el
-
sewhere in this article. Install a valve extension if needed
• When the glue is full dry, fold the tire. There are a number of
methods for doing this, but essentially you want to fold the glued
surfaces in on themselves so that the tire is a convenient size. This
is the spare tire you will carry with you.
• The tire can be secured to the seat post or under the saddle by
a toe strap, velcro strap, electrical tape or in a bag made to carry
a tubular.
• When you will have a flat, remove the wheel from the bike as usual.
• Hold the wheel with the edge resting on your thighs or waist
with the valve hole closest to your body. Starting on the side of
the wheel furthest from your body, pinch, lift and roll the tire off the
rim. It sometimes helps to work loose a short section of tire from
the glue on one side, flip the wheel and work loose the other side
at the same location. This is where practice pays off. Technique
and having glued the tire correctly originally is more important than
hand strength. You can use a plastic tire lever to carefully help start
the process if needed.
• After you get a short section of the tire slightly off the rim, set the
edge of the wheel closest to the valve hole down on the ground.
• Using your body weight, continue to roll the flat tire off of the top
of the rim by pushing down towards the ground. After you get the
tire about half way off the rim, pick up the wheel and strip the tire
completely from the rim.
• Unfold your spare and insert the valve into the valve hole.
• Place the edge of the wheel back on the ground with the valve
hole at the top and the wheel resting flat against your legs.
• Bend over and using both hands begin stretching the tire onto
the rim with a very firm even pressure while working your way down
from the top of the wheel. The further you stretch the tire at this
point, the easier it will be to roll the last bit over onto the rim. As
you reach the last few inches, lift the rim up until it is horizontal with
the edge of the rim against your stomach. The area of the valve
hole will now be against your stomach with the as yet un-mounted
portion of tire furthest away from you. Maintaining the pressure, roll
the last bit of tire onto the rim using your thumbs. Do not use a tool
to pry the last portion over the edge of the rim.
• Check to see that the tire is evenly mounted, pushing and pulling
the tire into the center where needed.
• Blow up the tire using whatever method you prefer. Remount the
wheel in the bike.
• After you return home, re-glue the new tire following the methods
outlined in this article.
