Fast aero shapes
This Speed Concept is the fastest bike we’ve ever tested—and it’s six minutes faster than the previous model at Kona. The ultralight 800 Series OCLV Carbon frame’s drag-reducing Kammtail Virtual Foil tube shapes cut through the air.
Smart storage
Integrated fuel and hydration storage makes it simple and stress-free to stay strong without leaving your aero position.

Smooth ride
Top Tube IsoSpeed takes the edge off rough roads, keeping you fresher and less fatigued not only on your ride, but on your run as well.
Shimano Ultegra Di2
Ultegra Di2 R8100 is Shimanos most inspired drivetrain, packed with innovative, game-changing features. HYPERGLIDE+ technology allows for crisp, seamless shifts both up and down the gear range, even during maximal efforts. The new Di2 shifting system introduces Shimanos exclusive wireless integrated circuit, and the move to a 12 speed cassette ensures you have all the gearing you need. Ergonomics and aerodynamics have been enhanced at every turn, and you can set up the drivetrain just the way you like it via Shimano’s user-friendly E-Tube app.
Don’t forget your pedals
This bike doesn’t come with pedals because you’ll have a better time on your new bike if you choose your own. See the pedal guide to find the best pedals for your riding style. We recommend clipless road pedals for control and efficiency.
