Princeton Mach 7580 TSV2 Disc Brake Front Wheel

The Princeton Mach 7580 TSV2 Disc Brake Front Wheel was built for one thing: going faster in the conditions that actually decide races. Not a controlled wind tunnel at a single yaw angle, but the full, unpredictable range of wind directions you face on an open triathlon course or a time trial road closing off at speed. Princeton CarbonWorks developed the Mach 7580 TSV2 in direct partnership with INEOS Grenadiers — Filippo Ganna among them — and that collaboration is baked into every dimension of the rim profile. This isn't wheel development shaped by marketing calendars. It's shaped by athletes who make their living in tenths of seconds.

The TSV2 designation marks a real evolution from its predecessor. Princeton CarbonWorks claims a 6 percent average aerodynamic improvement across yaw angles from -20 to 20 degrees — meaning the full range of real-world crosswind exposure, not cherry-picked tunnel conditions. The 75mm deep, 80mm wide rim is an unusual combination: deep enough to generate aerodynamic efficiency at race pace, wide enough that the rim shoulder presents cleanly to the wind across a broad range of angles. The geometry is designed to manage crosswinds rather than simply resist them, which matters considerably when you're 40 kilometers into a TT effort and the wind shifts. What you get is a wheel that tracks with more predictability at the speeds where aero gains actually compound.

Princeton has also addressed rolling resistance with a thoroughness that goes well beyond the rim profile. The holeless tire bed eliminates the need for tubeless tape entirely, removing a variable that most tubeless setups still carry. The Tactic Racing ceramic bearings are treated with a dicronite dry-film lubricant coating — an ultra-low friction surface treatment that goes further than standard ceramic bearing preparation. At 925 grams for a front wheel at this depth and specification level, the weight sits in a reasonable range for a disc-compatible carbon tubeless build made to this standard. The construction reflects the priorities of riders who don't want to choose between aerodynamic performance and the confidence to ride hard in variable conditions.

Design Benefits

1. Aerodynamic Efficiency Across Real Yaw: The 75mm depth and 80mm external width were developed together to produce a rim shape that manages airflow across the full -20 to 20 degree yaw range you encounter on open courses. Princeton CarbonWorks claims a 6 percent average aerodynamic improvement over the previous version — a gain achieved by rethinking the entire wheel system, not just the rim outline. In practice, this translates to a wheel that feels planted and composed when crosswinds hit, rather than one that demands constant correction.
2. Holeless Tire Bed: Most tubeless setups rely on rim tape to seal the spoke beds — a layer that can shift, degrade, or introduce installation inconsistency. The Mach 7580 TSV2's molded holeless bed removes that variable entirely. Tubeless setup becomes more reliable and repeatable, with one fewer failure point to manage before a race or a long training block.
3. Tactic Racing Ceramic Bearings with Dicronite Coating: Ceramic bearings reduce friction relative to steel, but Princeton has taken that further by applying a dicronite dry-film lubricant to the bearing surfaces. Dicronite is an ultra-thin tungsten disulfide coating used in aerospace applications for its exceptionally low coefficient of friction. The result is a bearing package designed to minimize rotational resistance and maintain performance across a wide range of conditions and temperatures.
4. INEOS Grenadiers Co-Development: The TSV2's design was shaped in active collaboration with one of the world's leading professional cycling programs, including riders who specialize in time trial and pursuit disciplines. That means the aerodynamic priorities, handling characteristics, and crosswind behavior were validated by athletes with the sensitivity and feedback to distinguish meaningful gains from marginal ones — not just in the tunnel, but on the road.

Final Take

The Mach 7580 TSV2 is built for the rider who takes time trialing and triathlon seriously — someone who has already optimized their position, their power output, and their pacing strategy, and is now looking at every remaining watt. It suits riders who want a front wheel that earns its depth through predictable crosswind behavior, not just straight-line tunnel numbers. If that describes your racing, this wheel was developed with you in mind.
