Ratchet This is a required option.

DT Swiss hubs use star ratchets and are available in 4 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.

24T - Made out of hardened steel as e-bike specific.

EXP 36 - With only a single spring, making the hubs faster and lighter. More precise contact makes a longer lifespan.

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

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.

Coach 2024/02/14

Hi, I have 2019 Trek Speed Concept gen 2, I'm not sure if my frame can handle a 28mm wide wheel, do you make a wheel the would work on my Bike? I am most interested Sunflower disc design. Which wheels come with the 5 year warranty and crash replacement and what are included? Thank you, JQ

LightBicycle 2024/02/15

Hi Sir, Thanks for your inquiry! Is it your bike the same as below link? It only shows that it is okay to fit 25mm tires. We are not sure whether it fits 28mm wide wheels or not. It is better to check with your bike supplier. https://www.trekbikes.com/us/en_US/bikes/road-bikes/triathlon-bikes/speed-concept/speed-concept/p/22054/ If 28mm wheels can not fit, we also have 25mm wide full disc wheel. If you are interested in, we can send you some pictures on Feb 18th. We are on Chinese New Year vacation from Feb 9th~17th. Thanks, Lightbicycle

Brandon 2023/01/11

I love the new wheels I ordered recently! They roll really fast. I'm working on a custom project, and I'm wondering if it's possible to order a disc wheel painted green, specifically #69BB01 ? Also, I would like to have the option to put this on a disc brake bike in the future, but right now, it will go on a rim brake. DT350 hub model. Thank you, Brandon

LightBicycle 2023/01/11

Hi Brandon, It is really appreciated to hear that you like our wheels!It is okay to customize disc wheel in green #69BB01 color painted. But it will add extra cost, we have to buy the painting material and extra painting cost. Also, this kind of color painting is heavy, it needs to make white painting first and add the green painting. It will make the wheel around 80g added at least. If you do not mind the extra cost and extra weight added, we can quote accordingly for you. Thanks, Lightbicycle

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
