Built for speed.
We love the steady sound of dual discs rolling on the track. Apparently, Zipp loves it even more than us. After all, Zipp's first products were disc wheels. And when you look at the technology and palmares of the Zipp 900 Track Tubular Wheel, it's easy to see that Zipp still holds its passion for the speed of discs.
For sheer rigidity, the 900 features a pure carbon fiber construction with a 21mm maximum width. Couple that with the added strength at the rim's edge from Zipp's Kevlar-stitched, Carbon Bridge technology, and you have a rim that's 50% stronger and ridiculously stiff in the lateral direction. And don't fear, these attributes didn't come at the pain of added weight. In fact, the rear 900 weighs in at roughly 1,130 grams, not only making it one of the lightest disc wheel in the Zipp arsenal, but also one of the lightest discs that we know of.
A number of Zipp technologies went into making the 900 the fastest and most powerful wheels in the Zipp arsenal. First, the Multi-Material Co-Molding process permanently fuses a sub-200-gram aluminum hoop to a dimpled carbon structure that acts as a leaf spring for vibration and impact. Spokes laced directly to the carbon body give you the benefit of a carbon feel and aluminum braking. Next, visco-elastic material is inserted between carbon laminate in the rim to reduce vibration by ten percent. Lastly, the dimples of the Aerodynamic Boundary Layer Control (ABLC) on the curved rim section work to create a slight turbulence directly above the rim surface. This creates an artificial boundary layer that forces the laminar boundary layer towards the forward part of the rim to become turbulent. This process enables airflow to remain attached over more of the rim for a longer period of time, providing a lower level of integrated drag. The drag that ABLC creates is called skin friction drag; although it's greatly increased, pressure drag (which is ten times higher than skin friction) is decreased to make the 900 wheels faster than the competition on the wood, not just the wind tunnel.
The Zipp 900 Track Tubular Wheel is available as an individual wheel. The front is 100mm spaced with a 15mm axle, and the rear is 120mm spaced with a 15mm axle. Please note that these are track wheels and are not road convertible. The rear wheel accepts a standard cog and lockring (1.37x24tpi).

hello. i am looking for track racing front...
hello. i am looking for track racing front disc wheel for my daughter. to be used on indoor track. she is light weight and i am looking for a light weight one. do you have anything lighter than zipp? currently using campy dics rear and mavic io front/custom made 5 spoke carbon depending on the condition.
We do not carry a huge inventory of track components, but feel free to email me directly at email@example.com, and I'll see what w can do to special order some wheels up. We do have a pretty great selection of brands for wheels, and I'm sure we can come up with something thats going to work great for your daughter.
