Introduction
This manual covers the Bontrager Race XXX Lite Carbon tubular and clincher
wheelsets and the Bontrager Race X Lite Aero Carbon tubular wheelset.These
wheels are constructed with carbon composite rims. The carbon composite
material is very light weight and strong, but requires some special care and
maintenance. Before riding your new Bontrager carbon wheelset, read and
follow your Bontrager Wheelset Owner’s Manual, and also the following special
Bontrager carbon wheelset instructions.
Properly install your tires
The
Bontrager carbon clincher
wheelset uses clincher, or wired-on tires
(only). When installing or removing your clincher tires, do not use metal tire
levers. The maximum inflation on this wheelset is 120psi (8.3atm). Overinflation
may damage the rim.
The
Bontrager carbon tubular
wheelsets use tubular type tires (only).
Do not ride these wheels without properly attaching the tubular tires. Tubular
tires require regular maintenance and inspection for attachment to the rim.
Failure to properly fasten, inspect and maintain the tires may cause the tire to
separate from the rim causing a loss of control resulting in injury. For instruc-
tions on fastening tubular tires to these rims, or maintaining tubular tires,
consult the tire manufacturer, or your dealer.
Prior to the first application of rim cement on a new carbon fiber rim the
tire well or bed, where the tire contacts the rim, should be roughened. It is
recommended that this procedure be done by your dealer. To roughen the tire
well of the rim, lightly sand with a 400 grit sandpaper.
Use only carbon-specific brake pads
Carbon rims require special brake pads to prevent heat fade and to work
properly in wet conditions. Heat fade is a loss of braking performance after
long, hard brake application. Carbon fiber rims also can be extremely abrasive
in wet conditions, causing standard brake pads to wear prematurely. Only use
Bontrager Carbon Brake Pads or a similar product with carbon fiber rims.
If your bicycle has carbon fiber rims, also follow the carbon fiber composite
inspection procedures.
With carbon rims, avoid certain chemicals, abrasives, or
extreme heat
When cleaning composite parts, do not use solvents, abrasives, or harsh
chemicals. Remove road film with a soft rag and a mild detergent and water
solution. Use of industrial solvents for cleaning or glue removal may damage
not only the rim finish but also the adhesive which joins the rim parts. To clean
rims, wipe them with acetone and a clean soft cloth.
Excessive heat, such as that used in powder coating, or any open flame, may
damage the adhesive which joins the rim parts. Do not exceed 180º F. (82º C.)
exposure to your composite rims.
Removing paint from an OCLV rim requires special techniques and so should
