Zipp 303 Tubeless Disc Brake 177D 650B Carbon Clincher Rear Wheel

A smaller diameter 650B rear wheel from Zipp, the disc brake specific 303 Tubeless Carbon Clincher is a versatile option that boasts a number of key uses.

Smaller riders are beginning to benefit from the production of framesets designed for 650B wheels, providing them with handling quality to match the larger 700C versions. This smaller diameter wheel also reduces the likelihood of toe overlap, providing additional safety to the rider. Another advantage this smaller diameter 650B rear wheel has over a standard-sized 700C wheel is that it can be paired with wider tyres to bring the overall wheel diameter closer to the standard road bike size. That means riders of standard-sized framesets can benefit from having more air between the rims and the road surface for a more comfortable ride. Or, fit off-road tyres and get out exploring trails with maximum comfort. This is all made possible by the advent of disc brakes on road bike framesets.

With no requirement for a braking surface on the rim, Zipp's Aerodynamic Boundary Layer Control (ABLC) dimples can extend all the way to the outer edge. This provides excellent aerodynamic performance, especially in a crosswind.

The rims are designed to be ridden with tubeless tyres, which offer advantages in lower rolling resistance and overall weight. However, tubes and clincher tyres can also be fitted if you prefer.

The Zipp 177D hub is a best-in-class offering and is noted for requiring less maintenance than other hubs, leaving you with more time for riding your bike. This highly versatile rear wheel comes with both a quick release and 15mm thru-axle end caps.
