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. 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 conventional hub. Slotting the hub flanges to accommodate bladed spokes is not recommend- ed and will void the warranty. Complete wheel building hub dimensions are listed in TABLE 2.
