This has been my trainer bike for the last 6 years. I upgraded the front fork to the Easton aero carbon fiber fork and also had it custom painted 3 years ago. All the internal wiring is on the bike, so it should be turnkey to put on the components you desire. This frame requires 650c wheels.

Information from Kestrel's website:
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 down tube 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.
