AERODYNAMIC & CLIMBING EXCELLENCE

The Venn 500 C UL strikes the ultimate balance between gravity-defying weight and wind-cheating aerodynamics. The 50mm profile delivers superior speed on the flats, while the ultra-low 998g system weight makes them a formidable weapon on the steepest climbs. The expansive 30mm external and 25mm internal width creates a seamless aerodynamic transition with modern, wider road tires.

ADVANCED CONSTRUCTION & FINISH

Crafted with our most advanced carbon layup techniques to strip away every unnecessary gram. These rims feature a pure, raw matte finish without any clear coat, a testament to our flawless manufacturing process. For riders wanting a personalized touch, we offer optional UV printed decals directly on the rim surface.

PREMIUM COMPONENTS

Equipped with our highly reliable 36-tooth ratchet hub system and premium S&S ceramic bearings, the 500 C UL delivers instantaneous power engagement and frictionless rolling efficiency. Fully tubeless-compatible, the wheelset comes with tubeless tape for either traditional clincher or modern tubeless setups.

Raw Matte Finish & UV Decals

By perfecting our mold extraction and resin formulas, we are able to offer the 500 C UL with a pure matte finish that requires no heavy clear coat. This not only shaves critical rotational weight but also showcases the pristine quality of the underlying carbon structure. For added customization, riders can opt for high-durability UV printed decals.

Aerodynamic Profile

The 50mm depth is meticulously sculpted to maintain sail-effect propulsion in crosswinds while minimizing steering torque. The ultra-wide 30mm external and 25mm internal dimensions perfectly support 28mm to 32mm tires, dramatically reducing rolling resistance and significantly improving comfort and grip on rougher tarmac.

Carbon Blade Spoke Technology

Laced with a lower count of carbon aero blade spokes, this wheelset offers an exceptional stiffness-to-weight ratio. Carbon fiber's near-zero elongation under load ensures that every watt of your power translates directly to forward motion, while the bladed profile slices through the air with minimal drag.

Questions riders ask

How does the Venn 500 C UL achieve a sub-1000g weight with a 50mm depth?

Achieving a 998g wheelset weight required optimizing every single component. We utilized advanced carbon layup techniques, removed the traditional clear coat in favor of a raw matte finish, and integrated ultra-light carbon aero blade spokes with a state of the art ratchet hubs.

What tire sizes work best with the 25mm internal width?

The wide 25mm internal width is perfectly optimized for modern, high-volume road tires. We highly recommend tires between 28mm and 32mm. This setup maximizes aerodynamic airflow over the 30mm external rim, lowers rolling resistance, and allows for lower tire pressures to enhance comfort and grip.

What are the benefits of the raw matte finish and UV printed decals?

Skipping the traditional clear coat saves rotational weight at the perimeter of the wheel, making accelerations feel snappier. The optional UV printed decals are applied using advanced ultraviolet curing technology, ensuring high durability and a premium aesthetic without adding heavy layers of paint or thick stickers.

Are these wheels durable enough for daily riding?

Absolutely. Despite their ultra-light weight, the carbon spoke lacing, premium S&S ceramic bearings, and robust 36t ratchet hub are designed to withstand the rigors of high-mileage training and racing. The raw carbon finish is exceptionally resilient to standard road debris.

How much does the Venn 500 C UL weigh?

The 500 C UL wheelset weighs just 998g, a sub-1000g system weight that's exceptional for a 50mm-deep aero wheel, making it fast on the flats and featherlight on climbs.

Which freehub options are available for the 500 C UL?

Shimano HG, SRAM XDR, and Campagnolo N3W freehub bodies are available, covering all major 11- and 12-speed road drivetrains. Choose your freehub at checkout.

Are the 500 C UL wheels tubeless-ready?

Yes. The 500 C UL is tubeless-ready and ships with tubeless tape and valves included. The 25mm internal width pairs well with modern 28-32mm tubeless road tires for a smooth, aerodynamic tire-to-rim transition.

Is a 50mm-deep wheel hard to handle in crosswinds?

The 50mm profile is tuned as an all-round aero depth, it delivers clear watt savings at speed while staying controllable in gusts. Riders in consistently windy areas sometimes pair it with a shallower front, but most find the 500 C UL composed across conditions.
