The KM-40 Airfoil

Description
The Europeans still call it The Race of Truth: Just you, the bike, and the clock. To this merciless discipline Kestrel humbly dedicates the KM40 - every inch of it designed, tested and re-designed to yield just one result: the near perfect translation of muscle power into forward speed. The KM's geometry is specifically tuned to the flat-back time trial position, while the design's outstanding vertical compliance isolates the rider from bumps and road shock. The massive downtube is both exceptionally stiff and aerodynamically optimal; 650c wheels and our unique seat tubeless design make the KM one of the slipperiest bikes on the Queen K Highway...or anywhere else. No wonder Kestrels (and, increasingly, the KM) have proven themselves the most popular bike at the Ironman, year after year. KM40 Airfoil: 3.1 lbs, one-piece frame with EMS Pro/650 fork. Available as frameset or complete bike.
