The PowerTap SL hub is compatible with Shimano 8, 9, and 10 speed systems or
Campagnolo 8, 9, and 10 speed. Free hub bodies may be interchanged. See page 24 for
instructions.
Only insert the correctly spaced PowerTap hub into your frame.
For example, only use a 130mm-spaced hub in a 130mm road frame. Do not force the hub
into any frame. Doing so may cause failure of the frame, hub, or both, and will void the
warranty. Contact your dealer or PowerTap to address any special compatibility issues.
WWHHEEEELL BBUUIILLDDIINNGG
Contact your local wheel building professional or dealer for assistance in building the PowerTap
hub if not provided as a complete wheel. The flanges are drilled for 14 or 15 gauge spokes. Use
at least a two-cross pattern on both sides of the hub. Due to the design of the hub, the load path
is not the same as with a conventional hub. Slotting the hub flanges to accommodate bladed
spokes is not recommended and will void the warranty.
