Zipp have boosted their range with the introduction of two clincher wheelsets with carbon rims and aluminium braking tracks.
The Zipp 30 Clincher and Zipp 60 Clincher, named after their respective rim depths, have been introduced as more affordable alternative to the firm’s more expensive wheels, borrowing some of the aero technology used further up the range.
Both use an toroidal aluminum rim braking track with a maximum width of 21.5mm on the Zipp 30 and 23.5mm on the Zipp 60, creating a bulbous profile which, while not as wide as the full carbon Firecrest 202 (unveiled last year), 303 and 404 hoops, smoothes air flow and reduces drag, thereby improving aerodynamics, according to Zipp.
The wide tyre bed is also said to enhance cornering grip and increases ride comfort, but only the Zipp 60 has the same dimpled appearance as the Firecrest wheels.
The wheels use a new 10 or 11-speed compatible hub, formed from 7075-T6 aluminum with stainless steel bearings, laced with Sapim CX-Ray spokes with external nipples. Both wheelsets have 18 spokes at the front and 20 at the rear.
Claimed weights are 765g front/890g rear for the Zipp 30 and 850g front and 970g rear for the Zipp 60. They’ll be available from March and UK prices have been set at £305 front/£370 rear for the Zipp 30 and £540 front/ £660 rear for the Zipp 60.
