question about your track wheel system that this manual does not cover, consult
your Bontrager dealer. If you have a question or problem that your Bontrager

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).
