Bontrager TUBULAR - TIRE Installation And Care Manual

Before mounting a tire, make

sure that the tire is the correct

size for the wheel on which it

is to be mounted. Use only rim

cement that is specifically marked

for gluing tubular tires. If you

have further questions, or do not

understand these instructions,

consult your Bontrager dealer.

To prepare the tubular tire

and rim

If the rim is new, use a fine emery

cloth to roughen the well of the

rim to improve adhesion.

or acetone.

of rim cement only to the rim.

Holding the tubular at the valve,

insert the valve into the valve hole

of the rim (Figure 3).

2.

With both hands, and working in

opposite directions from the valve,

apply tension to the tubular as

you stretch the tubular into place

on the rim.

Keep the valve stem straight in the

valve hole.

3.

As you near the side of the rim

opposite the valve, lift the tire up

and into the rim well (Figure 4).

Avoid rolling the tire onto the rim.

If the tire slides across the rim

Inflate the tubular to between 110-

Prior to use, let the glued tire

and rim sit for a minimum of 24

hours. The rim cement requires

this time to cure for proper

adhesion.

tubular tires

Before each use, inflate the

tubular tire to the pressure

recommended on the tire label.

Also inspect the tire for any cuts

or abrasions to the tubular casing,

and for any cuts or fraying in the

base tape.

After use, inspect tubular tires

for any damage. Remove any

debris such as metal, glass, small

stones, or anything stuck in the

tread. Clean tires with a mild,

soapy solution. Do not use cleaning

products containing hydrocarbons,

dilutants, or corrosives.

Store tubular tires in a dry place

away from light, and maintain the

tire air pressure at 70-90 psi (5-6

bar).
