RAKTT is the fastest UCI legal road bike, bar none. Designed to maximize the performance of the rider, in aerodynamics, handling, stiffness, and weight, all while maintaining practicality.

This one goes out to the nerds like us, who worry about the angle of our cycling computer for aero, who take the bottle cages off to save those extra few watts for our local Tuesday night crit. We aren't all fast, but we're all in on being as fast as we can be, whether for masters race glory or a National jersey. If that's you, this is your bike. It's the fastest the UCI will allow, by a mile. 

Aerodynamics

There are few road bikes that take advantage of the UCI's new 8:1 aero rule, and none that do so as well as RAKTT.  Our fork and headtube achieve the lowest possible drag, and our seat tube uses the flow angle induced by your legs to propel you forward like no other bike on the market. Don't take our word for it - look at our data, included below, and our whitepaper for more details. RAKTT beats the fastest competitor aero road bike by a landslide. The aerodynamic performance gap between RAKTT and less aero "aero" road bikes is roughly the same as between those bikes and a beach cruiser - would you show up to your next race with one of those?

Usability

The fastest bike is the one that's ready to ride. You can attach any standard 1-1/8" stem and handlebar to your RAKTT, or use ours for maximum speed. Our bottom bracket is threaded, because creaky press fit solutions made for the lowest cost have no place on a high-end race machine. The RAKTT fits 34mm measured tires because comfort is fast, and long rides make fast riders - better yet, we didn't give up a single watt to do so. Our seatstays bow for comfort and planted cornering, too. 

Handling

RAKTT isn't just ludicrously fast in a straight line - we've tuned the stiffness and handling to create the ultimate race-ready, descent-carving machine.  Our fork and head tube angles are size-dependent so that everybody gets excellent handling. There's no point having the most aerodynamic bike on the market if you can't use it to fly down descents with your friends. Try us and see.

Aerodynamic Data:

We're sick and tired of aerodynamic claims presented at carefully picked, unrepresentative speeds, so we provide our data where it's actually useful - at what we call "cruising speed" (a speed that's representative of normal human club rides and most time in races, when small savings add up to big energy), and "sprint speed" (a speed more representative of attacks and sprints, when you want every advantage). And we're sharing data across the yaw angle range, because we don't hide behind a proprietary averaging method or cherry-picked data points. Large yaw performance matters more than you might think, because your bike and your body are often moving as you ride, creating artificial wind angles as you move, so we've designed for it - and we're proud to show you the results. For more details, check out the RAKTT whitepaper.  Data below is shown for our most real-world-relevant testing, with rider lower body on.

Our comparison shows the relative 2D performance of an airfoil now allowed by the UCI vs. previous limits. Note that this is in some ways a best case scenario, since a poorly-designed 3:1 section would typically degrade in performance more easily with poor design than a thinner section.
