what is it?

NEW in 2022! 

When every second counts.

In events where it's you against the clock, every aero advantage you can gain will help you place better. A disc wheel on the back of the bike is the most aerodynamic option you can have. With a solid lenticular shape, the flows over the wheel smoother than any spoked wheel, propelling you through the air faster, and shaving time of your next time trial or triathlon.

The rim brake version of the disc wheel featues a tubeless rime bed with a 19mm internal width, perfect for the 25mm to 28mm tires being used in these events. Developed using CFD analysis over dozens of possible wheel shapes, the lenticular shape is optimized for real world wind conditions.

We have all ben there, going as hard as you can in a time trial and missing out by a couple of seconds. You start to wonder where you could have made up those few seconds. Don't let your wheel choice be where that time was lost.

tubeless rim bed

Tubeless tires used to be overly heavy and rugged in order to increase flat protection. The newest tubeless tires are faster than the non-tubeless variants and offer superior flat protection. Increase your speed and decrease your chances of flatting out on course.

cfd testing

A new lenticular shape is featured on the disc wheel. CFD testing was done in conjunction with a bike frame with rotating wheels to optimize for higher speed riding (20mph+) in wind conditions between 0 and 10 degrees of wind angle (yaw angle). This represents 70%+ of riding conditions on a very windy course, and 90%+ of riding conditions under normal wind conditions.

Designed for speed

The lenticular angled disc wheel is truly optimized for going fast on real roads. 

TT/Tri Disc

We have seen it at every triathlon or time trial. Valve hole stickers! Whether it’s a piece of cut vinyl, or an OBX sticker leftover from your vacation, they never look right on a high end wheel. There are even companies dedicated to making nicer looking stickers to fit over the valve hole. However, with the new disc wheels we have a dedicated carbon fiber valve hole cover that tightens into place using an allen wrench. 

Why do I need it?

Pure speed events where every second matters. We have all been in that situation where you have raced your hardest only to have been beaten by somebody by a couple seconds. What could you have done differently?

Arm yourself with the most aero wheel option ever and never wonder “What could I have done?” again.

Time trials, triathlons, flat and fast road races. Places where you can put your head down, hammer on the pedals, and go for it! 

hear that whoosh

"Whoosh whoosh whoosh" is the only way to describe the sound of riding with a disc wheel. Hear that road and the wind flying past the wheel as you ride faster than you ever thought you could.
