CycleOps PowerTap - Manual (Page 8)

System Overview cont.
COMPATABILITY
The PowerTap SL hub is compatible with Shimano 8, 9, and 10 speed systems or Campagnolo 8,
9, and 10 speed systems. Freehub bodies may be interchanged. Reference FREEHUB
REPLACEMENT for further instructions.
The PowerTap is available in 130mm and 135mm axle lengths. 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 Saris Cycling Group to address any special
compatibility concerns.
WHEEL BUILDING
Contact a wheel building professional or dealer for assistance in building the PowerTap SL wheel
if not purchased as a complete wheel. Both sides of the PowerTap should be built using only a 3x
spoke lacing pattern. Due to the design of the hub, the load pattern is not the same as a conven-
tional hub. Slotting the hub flanges to accommodate bladed spokes is not recommended and
will void the warranty. Complete wheel building hub dimensions are listed in TABLE 2.
Reference a spoke-length calculator to determine proper spoke length.

IMPORTANT:
For your safety, the non-drive side of
the PowerTap hub must be built with
at least a 2x lacing pattern. Because of
the patented PowerTap design, torque
is transferred through the hub to the
non-drive side. Failure to adhere to
this precaution will void the warranty.
