RAKTT

The Best Aerodynamics on the Road

This one goes out to the nerds like us who worry about how the angle of our cycling computer affects our aerodynamics. Who take the bottle cages off to save those extra few watts at the 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 updated 8:1 aero rules, 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), read our whitepaper for more details, and refer to independent testing by the highly respected engineers at Tour Magazin; RAKTT beats the fastest tested competitor aero road bike by a landslide.

Usability

The fastest bike is the one that's ready to ride.

  • Attach any standard 1-1/8" stem and handlebar or use ours for maximum speed
  • Threaded BSA bottom bracket—no more creaky press fit on your high-end race machine
  • Clearance for 34mm WAM tires—comfort is fast, and long rides make fast riders
  • Designed to be fast both with normal round bottles and aero bottles

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, and our seatstays bow for comfort and planted cornering.

Finally, our bike's aerodynamics put stability first—no need to worry about crosswinds pushing you off your line. 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 it 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:

  1. Cruising Speed: This is what we call a speed that's representative of normal human club rides and most time in races, when small savings add up to big energy.
  2. 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. Data is shown for our most real-world-relevant testing, with rider lower body on. 

For more details, check out the RAKTT whitepaper.

Team TWENTY28

Over the next three years, TWENTY28 and Stromm will bring the team’s top time trialists and pursuiters into the wind tunnel to refine rider positioning, cockpit integration, and equipment selection—turning validated data into faster results.
