Corima 3-Spoke WS TT Disc Brake Clincher Front Wheel - Ceramic

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.

Design Benefits

1. Three-Spoke Carbon Architecture: The three-spoke structure is central to what makes this a serious time trial wheel rather than a cosmetic one. It provides a high degree of torsional stiffness — lateral flex under load is minimised, keeping your power transfer clean through corners and out of the saddle efforts. The geometry also reduces the number of surfaces intersecting the airflow around the wheel, contributing to its aerodynamic profile in a way that a 20-spoke build simply cannot replicate.
2. Ceramic Bearing Hub: Ceramic bearings reduce rolling resistance compared to conventional steel bearings by generating less heat and friction at speed. The efficiency gain at any single moment is small, but across a full time trial distance it accumulates into a measurable advantage. For athletes who have already optimised position, nutrition, and pacing, this is one of the few remaining mechanical gains available.
3. Disc Brake Compatibility: Running a disc brake front wheel gives you consistent, controllable stopping power regardless of weather conditions — a meaningful consideration for long-course triathlon events where conditions can change between morning and afternoon. The disc interface also removes rim braking tracks from the carbon surface, allowing Corima's engineers to optimise the rim profile purely for aerodynamic performance without any structural compromise for a braking surface.
4. Clincher Tyre Format: The clincher format means you can run the tyre of your choice — whether that's a high-TPI racing clincher or a more durable training option — without the logistical commitment of tubular gluing or the setup complexity of tubeless. On race day, that simplicity matters. You can swap a flat, adjust tyre pressure to conditions, and get rolling without specialist tools or a waiting period.
5. Wind-Tunnel-Informed Rim Profile: The WS TT's rim shape has been developed with direct input from professional racing, where aerodynamic drag reduction at realistic time trial speeds is the primary objective. The profile is designed to maintain stable handling characteristics in crosswind conditions — a critical trait for a front wheel, where aerodynamic instability translates directly into rider effort spent correcting course rather than maintaining speed.

Final Take

This is a front wheel for athletes who race against the clock — time trialists, triathletes, and anyone who lines up where position and equipment are as important as fitness. The ceramic bearing hub, three-spoke carbon construction, and disc brake compatibility make the Corima 3-Spoke WS TT a technically coherent choice for that context. If you are building a dedicated fast-course setup and want a front wheel with genuine racing provenance behind its design, this is where that search ends.
