No other cycling event proves who’s faster than a time trial or triathlon. It’s nothing but you and the clock, and every second counts, so don’t leave anything to chance. PowerTap has long offered the ultimate in performance measurement and real-time pacing tools, but all this with the aerodynamics offered by a disc wheel has, until now, been impossible.

The Zipp Disc wheel with PowerTap Technology offers the best weapon in your speed arsenal by combining Zipp’s expertise in creating wind cheating wheels and PowerTap’s precision power measurement for the accurate application of every last drop of energy at exactly the right time out on the course.

The Zipp Disc with PowerTap SL 2.4 is the first disc wheel with PowerTap Technology, co-developed exclusively by CycleOps Power and Zipp. By working with Zipp, CycleOps Power added PowerTap’s accurate power measurement to a disc wheel with less than 100 grams of added weight, a small price to pay for the precision in which power can help you pace and monitor performance in cycling’s most important event.

Of course the wheel makes no compromises with Zipp’s legendary aero performance or stiffness so that every last watt puts you closer to the finish line. In fact, if you step up to the Sub9 that Slipstream Sports will be racing this year you’ll benefit from the wheels’ amazing negative drag for a whopping 12 watt savings! The shape of this amazing wheel actually creates lift, propelling you down the road faster than the competition.

All this combined with PowerTap’s wireless technology allows you to measure every watt with no added sensors or wires on your aero machine. Zipp’s precision bearings, axle and free hub with ceramic upgrade option tops off the package.
