Incorporating all that weve learned in 21 years of working with carbon fiber, the 101 is the first aluminum wheelset to utilize Zipps cutting-edge aero technologies. Featuring the worlds only fully toroidal (pdf) aluminum rim in a 7000-series high-strength alloy, the 101 actually has more in common with Zipps carbon wheels than it does with any other aluminum wheel thats ever been made.

Like our carbon wheels, the 101 is a product of Zipps rigorous wind tunnel development process. Like our carbon wheels, it outperforms even deeper-section models from the competition. Like our carbon wheels, the 101 is handbuilt at our facility in Speedway, Indiana.

Designed for racing and everyday training, the 101 balances weight, reliability and aerodynamics. Its 30mm profile is deep enough to take advantage of Zipps exclusive toroidal shaping while holding the 101s weight to just 1484 grams. The result is a wheelset that weighs the same as the industrys aluminum benchmark but saves up to 42 seconds over 40km.

A 24.5mm rim width maintains the 101s aerodynamics even with 25mm tires. But the 101 can also be used safely with tires as narrow as 21mm  unlike other clincher rims of similar widths  because the rounded toroidal shape is narrower at the hook bead than in the middle. The 101s wide stance also resists pinch flatting, improves lateral stiffness, and provides a stable platform for precise handling on rough surfaces.

The 101 features Zipps 88 front and 188 rear hubs with an 18/20 spoke count.
