Princeton Mach 7580 TSV2 Disc Brake Rear Wheel

The Princeton Mach 7580 TSV2 Disc Brake Rear Wheel is Princeton CarbonWorks' first tri-spoke rear wheel, and it didn't arrive quietly. Developed alongside INEOS Grenadiers and shaped in part by the demands of Filippo Ganna — one of the most decorated time trialists racing today — the TSV2 represents the kind of product that only emerges when elite athlete feedback and serious engineering share the same brief. This is a wheel built specifically for racing against the clock, where every watt saved and every gram justified matters more than anywhere else in cycling.

The TSV2 is the second generation of the original TS tri-spoke, and the refinements are measurable. Princeton CarbonWorks claims a 6 percent average improvement in aerodynamic efficiency across yaw angles ranging from -20 to 20 degrees — a sweep that reflects realistic race conditions rather than narrow wind tunnel optimism. That improvement comes from deliberate iteration: real-world testing, tunnel hours, and the sort of granular feedback that only competitive racing at the highest level produces. The 75mm front and 80mm rear profile is purpose-built for time trial and triathlon, where the aerodynamic argument is clear, but the engineering beneath the carbon surface ensures the wheel earns its place in the build rather than just on the spec sheet.

At 980 grams, the TSV2 asks you to make no trade-offs between speed and structure. A proprietary integrated one-piece aerodynamic axle manages airflow around the hub, contributing to both aerodynamic efficiency and stability at race speeds. The 21mm internal width accommodates modern tire sizing, and full tubeless compatibility means you can run lower pressures for better compliance without the weight or risk of inner tubes. Available in Chrome, Gloss Black, Gloss White, and Gold, and compatible with Campagnolo, HG11, and XDR driver bodies, the TSV2 is built to slot into a range of high-performance race builds without compromise.

Design Benefits

1. Refined Aerodynamic Efficiency: The TSV2's tri-spoke architecture is designed to deliver a claimed 6 percent average aerodynamic improvement over the original TS across a -20 to 20 degree yaw range. That breadth of coverage matters in real racing, where wind direction is rarely constant and the ability to perform across a spread of angles is more useful than a single optimistic data point.
2. Integrated Aerodynamic Axle: The proprietary one-piece axle design manages airflow through the hub area — one of the more aerodynamically disruptive zones on any wheel. By integrating the axle into the overall aerodynamic architecture rather than treating it as an afterthought, Princeton CarbonWorks reduces drag and improves stability at the speeds where this wheel is meant to operate.
3. Tubeless-Ready Construction: The 21mm internal width and tubeless compatibility allow you to run wider tires at lower pressures without adding the weight or puncture risk of inner tubes. For time trial and triathlon racing on varied road surfaces, that translates directly into reduced rolling resistance and better road feel — two factors that compound over the course of a long effort.
4. Race-Validated Development: The TSV2 wasn't designed speculatively. Its geometry and aerodynamic profile were refined through actual competition use with INEOS Grenadiers, with input from athletes whose margins are measured in fractions of a second. That process produces a wheel designed to perform under race conditions, not just to impress on paper.
5. Driver Versatility: Availability across Campagnolo, HG11, and XDR driver bodies means the TSV2 integrates cleanly into most high-end race builds without requiring a dedicated groupset. Whether you're running a Shimano Di2 setup, SRAM AXS, or a Campagnolo-equipped machine, this Princeton CarbonWorks tubeless wheel fits the build you already have.

Final Take

The Princeton Mach 7580 TSV2 is a rear wheel built for one type of rider: someone who races against the clock and refuses to leave aerodynamic efficiency on the table. It suits the time trialist or triathlete who wants a disc brake rear wheel developed in genuine racing conditions, backed by engineering that goes beyond surface-level design. If that description fits your racing, the TSV2 is ready to work.
