Zipp 900 Tubular Rear Wheel 2013: When we introduced the 900 we changed expectations for disc wheels. We demonstrated that they didn't have to weigh as much as a small dog 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 and was still more than fast enough to help American cycling legend Kristin Armstrong to time trial victories galore.

Zipp was founded 20 years ago to produce carbon fiber discs that were lighter and faster than anything else available at the time. Today, the 900 still reflects that commitment to giving you the perfect tool for whatever situation you find yourself in.

This disc may also be adapted for track use. Available in the stealthy Beyond Black or distinctive Classic White decal options.

Zipp wheels for model year 2013, which begin shipping in October 2012, are compatible with cassettes of up to 11-speed to work with all modern drivetrains.
