Ratchet This is a required option.

DT Swiss hubs use star ratchets and are available in 3 different models with varying points of engagement.

18T - Deepest teeth, slowest engagement, least amount of maintenance, suitable for powerful riders.

36T - Happy medium, doubles the engagement points.

54T - Super fast engagement, but shallow teeth require more careful re-greasing and the thru-axle should be checked every ride.

EXP 36 - With only a single spring, making the hubs faster and lighter, more complete engagement of the 36 ratchet teeth for more precise contact, and therefore a longer lifespan.

EXP 54 - Upgraded from EXP 36 to gain incredibly faster engagement.

Brake System This is a required option.

Finish This is a required option.

The "Finish" relates to how the rim is coated or painted such as matte or glossy for the most common applications. Our Recon Pro and Falcon Pro rims feature BlackTek and come out of molds as a completed product, with an inherent scratch resistant and near flawless finish, eliminating the need for coating or painting (weight saved as well). We name this kind of superior finish the paintless.

Full Custom: This option (if provided here to choose) offers custom finish such as Satin/Matte/Glossy etc at no extra charge with added 100g/wheel and 1-2 weeks LONGER on manufacture. If you select this option and LEAVE YOUR REQUIREMENT IN QUOTES IN THE NOTES AT CHECKOUT, we will reach out to you once the order is placed to finalize the details.

Paintless

Full Custom

Weave This is a required option.

The layup schedule is predetermined for each model, but you can choose the outer layer for cosmetic appearence.

The purely hand-braided "Sunflower" weave paired with "Paintless" finish delivers a distinctively futuristic appearence.

TECH

The UFO-C21 full disc wheel featuring a hollow core is made of equally sized T800 carbon pieces and ultra-light special foam cores. The hollow design, compared to the traditional solid-core wheels, makes a great weight saving and significantly reduces the risk of delamination. The high-density foams add the torsional and lateral stiffness required in quick acceleration.

The result? A lightweight aero wheel to roll fast for years.
