Note: Production of the Zipp 900 Clincher ended in June 2012. Zipp will continue to provide ongoing support for this product through our normal sales/service channels.
This product has been replaced with our Super-9 Carbon Clincher disc.
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. The 900 continues to be the disc of choice for riders who want the speed of a disc and the ease of use of a clincher rim.
Rather than post-bonding a rim around a flat or lenticular disc, we've incorporated our patented toroidal rim shape and used our proprietary M2CM™ technology to increase strength while reducing drag around the interface of aluminum and carbon. For long-course triathletes, the bulged cross-section offers a comfortable vertical compliance that can reduce fatigue during long stretches in the saddle.
With the ease of clinchers and optimal aerodynamics for tires up to 23 mm, the 900 Clincher is the perfect choice on less-than-perfect road surfaces. Due to the shallow valve hole opening we recommend valve stems of 32mm or less for easier valve adaptor access.
This disc may also be adapted for track use.

Advanced Boundary Layer Control (ABLC) refers to the patented and instantly recognizable dimpled pattern found on all of our carbon rims. ABLC smoothes airflow across the rim's surface and is tailored to every model from the 202 to the Super-9 Disc. The third-generation of ABLC has up to four times more dimples than before.
Visco-Elastic Constrained Layer Control (VCLC) uses a vibration-absorbing material sandwiched between layers of rigid carbon laminate in the rim. When the wheel receives an impact from the road, much of the shock is absorbed by the VCLC system, delivering a 10% reduction in vibration.
Every aspect of our 88 and 188 hubs sets a new benchmark. The standard steel bearings are the roundest in the industry. The 17mm axle is the stiffest of any road hub we've tested. The wire EDM-cut hub internals are the most precise. When it comes to precision and performance, there's really no comparison.
Multi-Material Co-Molding (M2CM)ensures that Zipp clincher rims are the world's strongest. The process permanently fuses a sub-200 gram aluminum hoop to a carbon structure with the same dimpling as our tubular rims and our patented toroidal bulge, which acts as a leaf spring to reinforce the aluminum during impacts. The spokes lace directly to the carbon body for a fully structural rim that blends the ride feel of carbon with the braking performance of aluminum.
