Princeton Mach 7580 TSV3 Disc Brake Rear Wheel

The Princeton Mach 7580 TSV3 Disc Brake Rear Wheel is the third generation of Princeton CarbonWorks' tri-spoke design, and the fastest, lightest version the brand has built in this line. Where most aero wheels chase speed with a deep-section rim and traditional spoke count, the Mach 7580 uses a tri-spoke blade design, three wide carbon blades in place of a conventional spoke pattern, built to cut drag at speed while keeping the wheel light enough to matter on longer rides.

Princeton tested this generation before it ever had a name. In prototype form, the TSV3 already had a grand tour stage win and an Ironman World Championship victory to its name before the wheel officially launched on the eve of the 2026 Tour de France, four years after the first-generation Mach 7580 debuted. That's a meaningful detail for a rear wheel: this isn't a wheel designed in isolation and hoped into competition, it's one that earned its release date by winning races first.

This rear wheel weighs 900 grams on its own, and Princeton says a complete TSV3 wheelset (front and rear together) comes in 125 grams lighter than the previous TSV2 generation, a real reduction rather than a rounding difference. The rim and spoke blade profiles were redesigned specifically around 28mm to 30mm tires, reflecting where road racing has actually moved rather than where it was a few generations ago. Internally, it runs on Princeton's Tactic TR01 v2 hub with ceramic bearings, a ratchet-and-freehub system built to hold up under repeated hard efforts without dragging on engagement.

The rim itself measures 23mm internal (hook to hook) and 33mm at its widest external point, wide enough to properly support a 28-30mm tubeless tire without the tire ballooning past the rim's edge, and it's compatible with both clincher and tubeless setups, tubeless without needing tape thanks to the rim's tubeless-ready bed. Braking is handled through a Centerlock disc interface, and the wheel is available with a Shimano/SRAM HG11, SRAM XDR, or Campagnolo freehub body depending on your drivetrain. Princeton offers the Mach 7580 TSV3 across ten finishes, from Matte Black and Matte White through Gloss Chrome, Gloss Chameleon, and Gloss Cobalt, so it's possible to match or contrast against a frame rather than settling for whatever finish happens to be in stock.

For a rider who's already running a deep-section aero setup and wants to upgrade to something with real race results behind it, or someone building a wheelset one wheel at a time, the Mach 7580 TSV3 rear wheel is a legitimate step up from a conventional multi-spoke aero wheel. It's not a wheel for someone chasing the lightest possible climbing setup; the tri-spoke design and rim depth are built for holding speed on flat and rolling terrain, in time trials, triathlons, and fast group efforts where sustained speed matters more than a few grams saved on a climb.
