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.

Road-Rim-High-TG-Surface-Grooved-Graphene-Surface

Non Disc - High TG Surface: Rim Brake 700C road rims use an advanced High TG resin system with a layer of graphene to help dissipate heat. The braking power and reliability is significantly improved over a basalt braking surface.

Non Disc - Grooved Graphene Surface: Our new resin system and construction method, combined with the 3k rim track, withstands over 280°C, dissipates heat, and lowers rim temperatures faster in between braking efforts. Gain confidence-inspiring brake performance on the steepest descents and wettest conditions with our matching brake pads. Also, graphene added to the rim brake track allows for greater resistance to overheating with improved heat dissipation and reduced temperature accumulation during heavy braking. The grooved track helps evacuate trapped moisture between pad and rim in wet conditions, and brings more resistance and force at the lever when conditions are dry.

Full Custom: This option (if provided here to choose) offers custom braking track in other various weaves (UD/12K/3K twill etc) with 1-2 weeks LONGER on manufacture and extra $10USD/rim only as a start (with High TG Surface by default). If you select this option and LEAVE YOUR TAILORED REQUIREMENT IN THE NOTES AT CHECKOUT, we will reach out to you once the order is placed.

Disc: The disc version does not have a rim brake track and features a unique disc specific layup process. Our new layup is about 10g ~30g lighter by reducing the unnecessary material and utilizing elements of our Flyweight construction method.

Non Disc - High TG Surface

Finish This is a required option.

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.

COMMENTS

Carl 2021/12/02

Hi I see from the above comments the UFO-C21 Disc Wheel Rear Clincher Sunflower 70% Glossy is available as a rim brake option. I know you do a tri spoke front wheel but can not find it on your website. Is it possible to get the tri spoke front wheel with the sun flower pattern on it to match the rear disc wheel.?

LightBicycle 2021/12/03

Hi Carl, Thanks for reaching out! What width and depth do you want for the Tri-spoke wheel 700C and the Full-disc rear wheel? What width tire are you plan to run with? Thanks, Lightbicycle

Any chance the WUFO-C21 can be made for rim brakes?

LightBicycle 2021/12/01

Hi Avery, Yes, we can add a brake track to the trackwheel UFO-C21. Do you want our standard high TG brake surface or the grooved Graphene brake surface ($30/rim). Thanks, Lightbicycle

How much is the disc wheel? Are different hubs possible? Regards, Felix

LightBicycle 2021/11/27

Hi Felix, Thanks for reaching out! We offer 2 hub options, DT SWISS 350, and Chosen hubs. We can do the road version, disc brake version, and track version for the same disc-wheel. The cost is USD850 if it's with DT 350 hub. It's USD755 if with a Chosen hub. For the weave, we can do normal UD. Or the hand-braided "Sunflower" layup as you can see from the banner photos. Thanks, Lightbicycle
