Zipp has revealed its 2011 range of bars, stems, seatposts and wheels.

Zipp’s most popular wheelsets, the 404 Tubular, 404 Carbon Clincher, 808 Tubular and the new 808 Carbon Clincher have been overhauled with an aerodynamic rim named ‘Project Firecrest’.

Firecrest shifts the widest point of the rim inward towards the hub and tapers only slightly towards the tyre.

At a 10-degree wind angle, Zipp claim the performance improvements from Firecrest are nine seconds over 40km for the 404 Tubular and 15 seconds for the 808 Tubular.

Despite their upgraded aerodynamics, weights for Firecrest-based wheels remain light: 1278g for the 404 Tubular, 1557g for the 404 Carbon Clincher, 1519g for the 808 Tubular, and 1759g for the 808 Carbon Clincher.

“We worked for two years until the 404 Carbon Clincher was ready and now all that technology is making its way through the rest of the Zipp line,” said wheels product manager Bryan Hite.

The new Service Course line of aluminum bars, stems and seatposts has been put through its paces by US cyclo-cross champion Tim Johnson and the Cannondale Cyclo-Cross Team.

“Zipp has traditionally focused on composites and carbon fibre technology,” said product manager Nathan Schickel.

“But aluminum bars, stems, and seatposts started making a lot of sense as we spent more time talking to elite athletes about their needs and to bike fitters about their clients’ needs.”

In addition to the new aluminum products, Zipp has upgraded and expanded its carbon range. 

The VukaBull carbon base bar offers a redesigned wing profile that improves aerodynamics and strength, while the VukaSprint features a version of the airfoil section from the VukaBull.

And, at 102g, the SLSpeed stem in constructed entirely from unidirectional carbon and with titanium hardware.
