The Zipp 30 is a durable, high-performance wheel designed with proven aerodynamic principles. Many riders are finding wheels with a 30mm depth provide a perfect balance of durability, aerodynamics, stiffness and weight for a variety of riding conditions - even wind. Plus you get a great looking Zipp wheel with a black matte rim, black hubs and spokes and classic white decals at a very budget friendly price.
A 21.5 wide tire bead is a little wider than most and gives a couple benefits. The wider rim better supports the tire so you get a more solid feel in hard cornering. This also improves overall tire performance and ride quality due to the rim and tire being more inline. The 30mm deep aluminum rim with Zipp's wind tunnel proven hybrid toroidal shape provides an aero advantage exceeding many deeper "V" section carbon rims.
Zipp rolls out a new hub for the 30 with a hubshell made from ultra-strong and lightweight 7075-T6 aluminum. Sapim CX-Ray spokes maintain stiffness required for efficient power transfer. External nipples better support each spoke as it exits the rim. Stainless steel bearings ensure years of smooth riding. This hub is precision set, so it requires no pre-load adjustment.
Ships with Zipp Tangente butyl road inner tube with removable core (700c x 19-23mm), quick-release skewers and rim strips.
The Zipp 30 clincher has a 250 pound rider weight limit and a 125psi tire pressure limit
