The 3-Spoke Trilight C21 Disc is Here

From Triathlon Leg to Time Trial PR

Designed from the ground up for triathlon and time trial athletes, the all-new Trilight C21 disc joins our 3-spoke wheel family with smarter engineering, cleaner design, and incredible performance value. It's the next chapter in our pursuit of every possible gain against the clock — because in our sport, there's no such thing as a wasted second.

Streamlined Valve Interface

Say goodbye to awkward valve stickers and high-maintenance window covers. No adapters. No covers. No compromises. Guided by a sleek, minimalist philosophy, we've designed the valve interface to work exactly like a standard rim — clean, simple, and secure. The Trilight C21 disc features a direct-drilled valve hole — pair it with a standard 75 mm valve stem for cleaner aesthetics, enhanced structural integrity, and easier inflation.

Sculpted for Speed

Featuring an aero-optimized airfoil shape, the Trilight C21 Disc combines a rounded leading edge to channel airflow smoothly with a tapered profile to streamline air around the wheel. This allows you to hold high speeds with less effort — making every watt you generate go further. Whether you're holding a steady pace on the triathlon leg or racing against the clock for a new personal best, the Trilight C21 disc works with you, not against you.

Hooked. Rated. Ready.

The Trilight C21 disc centers on a versatile hooked bead profile, so you can run 25C to 35C tires with complete confidence. We've optimized our hub configurations to shed overall system weight and boost performance — all at a dramatically competitive price point. Weighing just 775g and priced at $600, this 3-spoke front wheel goes head-to-head with setups costing hundreds more. And it's no fragile race-day ornament: with 70J impact strength and a 130kg / 287lbs rider limit, this is a true workhorse forged for real power on real roads.
