manuals thoroughly before using your new track wheel system; they contain
important safety and maintenance information.

This wheelset, like all track wheels, is designed to be used in a bike frame
with 120mm OLD (Over Locknut Dimension) rear spacing as a 1-speed wheel.
Track wheels with tubular rims are designed to be used with properly attached
tubular-type tires.
The Bontrager Wheelset owner's manual explains how to inspect, adjust, and
lubricate Bontrager wheels. The Bontrager Race X Lite Carbon wheelset supple-
ment explains how to properly use and maintain carbon fiber rims. This section
explains information specific to track wheelsets to users familiar with track
wheels.
Track wheel specifications
The bicycle frame and parts must conform to these fit parameters:
• 120mm +/-1.5mm O.L.D. (Over Locknut Dimension). To use this wheelset
in a frame with wider dropout spacing, a longer axle and spacers must be
installed to provide proper dropout alignment and adequate axle-nut thread
engagement.
• 1.37" x 24tpi ISO cog or freewheel threading. Loose-fitting threads may
damage the hub.
• Left-hand 1.29" x 24tpi lockring threading
• Standard M10x1 axle threads
• Optional axle locknuts with 25.0mm diameter for use with aluminum
frame dropouts (PN 68258).

Installation of parts
Incorrect installation of parts may damage the wheelset.
To install a track cog
Only install a track cog on the side of the hub with lockring
threads (Figure 2). If necessary, remove the thread cover and
install the cover on the other side of the hub.
1. Make sure the threads are clean and free of debris.
2. Apply a light coat of Wrench Force® synthetic grease or a
similar lubricant over the threads.
See your dealer for a recommended grease.
3. Start threads by hand, and install the cog.
4. Tighten the cog.
5. Follow steps 1-4 to install the lockring.
To install a single-speed freewheel
Only install a freewheel on the side of the hub without lockring threads. If
necessary, remove the thread cover and install it on the other side of the hub.
1. Make sure the threads are clean and free of debris.
2. Apply a light coat of Wrench Force® synthetic grease or a similar lubricant
over the threads.
See your dealer for a recommended grease.
3. Start threads by hand, and install the freewheel.

Maintenance
Once a month, apply a drop of oil between the axle nut and its captive washer

Once a month, apply a light coat of Wrench Force® synthetic grease or a

grease.
Once a month, adjust the hub bearings.
Special user information
Carbon fiber rims require special care and maintenance.
Tubular tire installation
When preparing these rims for tubular tire installation, do
not sand the rims. Sanding may remove carbon fiber, which
may weaken the rim and cause it to fail. To clean rims, wipe
them with acetone and a clean soft cloth.
