We can’t prove it, but it’s likely that T4s have done more laps on the boards than any other production track bike in history. It’s built to excel in the fiery intensity of track racing, and turn watts into speed like nothing else in the world.  We applied everything we learned from our category-leading time trial bikes and optimized it for the demands of track racing—where every microsecond counts. It’s one of the most aerodynamic frames we make, and it’s stiff enough to stand up to the stacks of muscle elite track racers call quadriceps.
