The only thing better than training with power is racing with power. Reviewing race files is an eye opening experience for everyone -- both about what you can do on race day, and about what you need to improve upon most. The beauty of building your Power Tap SL 2.4 on a Zipp rim is that you get an amazing depth of data, but you don't have to sacrifice a whit of the lightness or aerodynamics you gain by riding a set of Zipp wheels. It's the best of all worlds.

We build our Power Tap SL/Zipp wheels out of the 24 hole version of the SL 2.4 hub with Sapim CX-Ray spokes. CX-Ray spokes are made from high-tensile stainless steel. On the one hand they offer supreme corrosion-resistance and fatigue-proofness, but on the other hand they're as feathery light as Ti spokes. Best of all is their aerodynamics -- their bladed profile accentuates the wind-cheating advantages inherent to a Zipp rim.

We offer every Zipp rim option -- all the way from the climbing-minded 202 to the aerodynamic delight of the 808. We also offer your choice of tubular or clincher

The Power Tap SL 2.4 comes compatible either for Campagnolo and Shimano. Each system comes complete with Power Tuned Agent 7.0 Software which is Mac and PC compatible, computer head and harness and the USB interface so you can download the data from your handlebar-mounted cpu to your desktop.
