Princeton Mach 7580 TSV3 Disc Brake Front Wheel

The Princeton Mach 7580 TSV3 Disc Brake Front Wheel is a carbon aero front wheel built around Princeton CarbonWorks' variable-depth Mach platform, with a profile that runs between 75mm and 80mm as the model name indicates. It's sold here as a front wheel only, so it's a natural fit for a rider replacing a single wheel, building a mixed-depth front/rear setup, or pairing it with a matching rear wheel purchased separately to complete a full aero wheelset.

Princeton builds the rim in carbon with a 23mm internal width and 33mm external width, which puts it solidly in the wider-rim camp that's become standard on modern aero wheels. A wider internal bed gives tubeless tires a more supported, rounder profile at lower pressures, which improves both rolling efficiency and cornering grip compared to older, narrower rim designs. The wheel is set up for clincher or tubeless tires, giving a rider the choice to run tubes for simplicity or go tubeless for the ride quality and flat protection tubeless setups offer.

Princeton pairs the rim with its Tactic TR01 V2 hub, built with ceramic bearings. Ceramic bearings run with lower friction than standard steel bearings, which translates to less rolling resistance at the hub over the life of the wheel. The wheel uses a centerlock disc brake interface, which simplifies rotor mounting and keeps the brake interface consistent with the disc-brake standard most modern road and race bikes have settled on. At a claimed weight of 880 grams for the complete front wheel, it sits in a reasonable range for a deep-section aero wheel that still needs to hold up to regular training and racing.

The 75-80mm depth range places this wheel toward the deeper end of the aero spectrum without going as deep as a dedicated time trial disc wheel. That range is typically chosen by riders who want the aerodynamic benefit of a deep rim on flatter, faster courses while keeping handling manageable in crosswinds — a depth much beyond 80mm starts to catch more wind on the front end, where handling stability matters most. For a front wheel specifically, that tradeoff matters even more than on the rear, since the front wheel is what a rider actually steers.

This wheel suits a road racer or a rider doing regular fast group rides who wants a genuine aero upgrade on the front end without sacrificing predictable handling, particularly on rolling or flat terrain where aero depth pays off over the length of a ride. RA Cycles carries it in Matte Black. Riders building a full wheelset around this front wheel should plan to pair it with a compatible Princeton rear wheel or confirm hub and axle compatibility with their current bike before ordering.
