Madison Street Waterloo, Wisconsin 53594 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 supplement 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). 2 Installation of parts Incorrect installation of parts may damage the wheelset. Lockring threads 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. Figure 2- Track-cog side of hub 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. 4. Tighten the freewheel. WARNING An improperly installed or tightened track cog can cause you to lose control and fall. Make sure the cog and lockring are positioned and tightened properly before riding the bike. Maintenance Once a month, apply a drop of oil between the axle nut and its captive washer (Figure 3). Once a month, apply a light coat of Wrench Force® synthetic grease or a similar lubricant over the axle threads. See your dealer for a recommended grease. Once a month, adjust the hub bearings. Special user information Carbon fiber rims require special care and maintenance. Oil here 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.
