The Fastest Bike

Why no seat tube?  We are asked this question all the time.  We didn’t design this bike without a seat tube just because…  We studied hours of wind tunnel data to learn how to make our bikes faster.  By creating a radical, “open” triangle, wind drag created by the rider’s movements was drastically reduced. So what’s that mean? It means the Airfoil is at its best when being ridden. And isn’t that what is really important? Aero, 20% stiffer, and only 17 lbs  – the Airfoil Pro SL is simply the fastest Ironman-inspired bike available today. A true work of art.

Also available as a frameset:

  • Frame Weight: 2.27 lbs.   
  • Fork Weight: .95 lbs.
  • Sizes: 47cm, 50cm, 52cm, 54cm, 56cm, 59cm
