Nothing beats the ride of Zipp wheels. So, why not use them for racing and training? The 101s utilize Zipp's knowledge of aerodynamics for speedy and durable aluminum wheels. A unique rim shape that's 30mm deep is the secret to the speed, and with a feathery weight, you'll have an advantage on every ride. Plus, just like on their full-bore race hoops, you get super-smooth Zipp hubs and the confidence of having the fastest aluminum wheels on the road.
