When Zipp introduced the 900 they changed expectations for disc wheels. Zipp demonstrated that a disc wheel can be almost as light as a climbing wheel while offering the stiffness necessary to perform under the world's greatest cyclists. At just 935 g with a cassette hub, the 900 is light enough for the hilliest triathlon or time trial courses.
The Zipp® 900 disc remains one of the lightest, stiffest disc wheels in the world Its 21mm width and uniform cross section mean it will work even on very tightly spaced TT bikes. This latest version is compatible with cassettes of up to 11-speed to work with all modern drivetrains.
This disc may also be adapted for track use with a track axle sold separately. This wheel has the new, more stealthy Black decal. Includes skewer, valve extender, disc pump adapter, and valve hole decal.
