"SRAM is introducing a wheel line for 2009...why? SRAM President Stan Day has always wanted SRAM to be a company that offers a full range of components and after the acquisition of Zipp, we realized we could offer a broader choice of products in the wheel category. Zipp is our high end, elite branded wheel product, while SRAM wheels will satisfy the demand for high-quality, well-engineered wheels for aftermarket and OEM." ..."SRAM will offer three different carbon wheel models with different rim depths; SRAM S40 / S60 / S80. Each SRAM wheelset will be built by Zipp and will offer a deep rim profile with unique hybrid torroidal shape, structural woven carbon rims with a aluminum braking surface and a special 6-pawl freehub for rapid engagement and cartridge bearings for low maintenence. The specs of SRAM's new wheel line are impressive and break down like this: Designed for fast, hilly rides, SRAM S40 has a 38mm X 20mm rim with 18 front & 20 rear spokes. Claimed weight is 725g. front & 890g rear in either Campagnolo or Shimano freehub and black or silver anodized spokes."
