SRAM subsidiary Zipp Speed Weaponry will debut two all-new disc brake-compatible wheels this summer, timing the release with the upcoming formal unveiling of SRAM’s hydraulic disc brake-ready road groups. The company will pair its versatile 303 Firecrest tubular and carbon clincher rims with new 88/188 Disc hubs.
The wheels are designed for both cyclocross and road use, with added spokes and burlier hubs to account for the stresses caused by disc brakes.
The 45mm tall 303 has long been the versatile mainstay of Zipp’s line, utilizing a wide, carefully engineered shape to optimize aerodynamics and crosswind control. Its low weight has made it a popular cyclocross rim in addition to seeing plenty of road use. It is not surprising, then, that Zipp has chosen it for its first road disc experiments.
The available rims are identical to the current 303 Firecrest clincher and tubular options, which means they retain a normal brake track.
Zipp’s new 88/188 Disc hubset will feature a newly designed 11-speed compatible freehub that takes advantage of a larger bearing, still Swiss stainless steel, and a custom cartridge in the rear hub for added durability. The rear hub is spaced to the 135mm mountain bike standard for compatibility with the latest disc frames, and will be available with Shimano/SRAM or Campagnolo freehubs.
Availability is set for July of this year.
