The Corima 3-Spoke WS TT Disc Brake Clincher Front Wheel - Ceramic is built for one purpose: getting you across a finish line faster than anything else you could put at the front of your bike. Three carbon spokes. A wind-tunnel-validated profile. A hub loaded with ceramic bearings. Every decision in this wheel's construction traces back to the demands of time trial and triathlon racing, where aerodynamic drag and mechanical efficiency are the two levers a rider can actually control.
Corima has been developing three-spoke carbon wheels since the early 1990s, and that depth of experience shows in the WS TT. The three-spoke architecture isn't a styling choice — it delivers a torsional rigidity that a conventionally spoked wheel can't match at comparable weight, while the reduced number of structures cutting through the air contributes to the wheel's aerodynamic profile. Corima developed the WS TT in close collaboration with professional teams, and the geometry reflects feedback from riders racing at the highest level of the sport, people for whom a poor-handling front wheel in a crosswind isn't an inconvenience — it's a race-ending problem.
The ceramic bearing variant takes the hub's rolling efficiency a step further. Ceramic bearings generate less friction than steel at racing speeds, meaning a smaller percentage of your power output disappears before it reaches the road. In a 40-kilometre time trial, that's not a one-time saving — it compounds across every pedal stroke. Pair this with a rear disc and you have a front-end setup that leaves very little aerodynamic or mechanical efficiency untouched. The clincher format keeps race-day logistics manageable: mount a quality clincher tyre, set your pressure, and focus on pacing rather than tyre preparation.

The Corima C+ WS TT Disc Brake Clincher Disc Wheel is built around a single premise: in time trial and triathlon racing, the rear wheel is not a supporting character. It is the aerodynamic anchor of the entire setup, and it demands to be treated that way. Corima has been engineering carbon wheels for professional competition for decades, and the C+ WS TT represents their answer to a specific question — what does a full disc rear wheel look like when it has to work with disc brakes and clincher tires without conceding an inch on aerodynamic performance?
A full disc rear wheel works because it eliminates the drag-generating turbulence that spoked wheels produce. There are no spokes to interrupt airflow, no gaps to create pressure differentials — just a continuous carbon surface that slips through the air with a consistency no conventional deep-section wheel can match. Corima's construction process is developed in the wind tunnel, producing a disc profile shaped to remain manageable in the crosswind conditions that are a constant fixture of real race courses, not just straight-line laboratory runs. The tradeoff with any disc wheel is always rotational inertia — mass at the rim matters more than mass at the hub — so Corima's carbon layup is engineered to keep weight in check without compromising the structural rigidity a disc wheel needs to transmit power cleanly under load.
The disc brake-compatible format places this wheel squarely in the modern era of time trial and triathlon equipment. Hydraulic disc brakes have become standard specification on high-end TT frames, and the C+ WS TT is built to integrate with those systems without requiring any aerodynamic compromise. The clincher tire format extends its practicality further — you get the race-day aerodynamic advantage of a full disc rear wheel alongside the logistical straightforwardness of clincher tires, which are easier to source, easier to change, and easier to manage across a race weekend. Three driver options — Campagnolo, Shimano/SRAM 11-speed HG11, and XDR — ensure compatibility with the drivetrains most commonly found on contemporary TT bikes.
