Super-9 Carbon Disc Wheel

What Our Gearhead® Experts Are Saying:

"I switched to the Super-9 Carbon Disc Wheel after years of running rock hard tire pressure on race day, and dropping pressure with this wheel actually felt faster, not slower. The hookless rim and 28mm tire pairing held cornering confidence I wasn't expecting from a disc wheel, and the ceramic bearings felt noticeably smooth spinning up out of transition."

Long course triathlon and time trial racing reward riders who understand that comfort and speed aren't opposites, and the Super-9 Carbon Disc Wheel is engineered around that exact insight. Built on Zipp's Total System Efficiency approach, the wheel targets all four barriers to speed at once: wind resistance, gravity, rolling resistance, and vibration loss, rather than optimizing for aerodynamics alone.

A hookless carbon rim with 23mm internal and 30.4mm external width is purpose built for 28mm tubeless tires run at lower pressure, a shift away from the traditional high pressure setup that riders have relied on for years. The ZR1 SL hub spins on ceramic cartridge bearings with 66 points of engagement, while an integrated TyreWiz 2.0 monitor keeps tire pressure precisely dialed without needing a separate gauge. A redesigned pump access port with an integrated cover simplifies final inflation checks trackside.

Compatibility is tubeless specific, with 28mm listed as both the minimum and optimal tire size and a max tire pressure of 73psi (5.0 bar). The wheel ships with SRAM XDR and SRAM/Shimano Road driver body options, with a Campagnolo driver sold separately, and pairs with disc, Centerlock brake systems on modern triathlon and time trial platforms.

This wheel is built specifically for triathlon and time trial racing, where sustained comfort over distance and consistent handling through corners translate directly into saved energy, energy triathletes need for the run still ahead.
