PowerTap SL 2.4 - Manual (Page 8)

System Overview cont.
COMPATABILITY
The PowerTap SL 2.4 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 (Road) and 135mm (MTB) 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 SL2.4
wheel if not purchased as a complete wheel. Due to the design of the hub, the load pattern is
not the same as a conventional hub. Slotting the hub flanges to accommodate bladed spokes is
not recommended and will void the warranty. Complete wheel building hub dimensions are list-
ed 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.
