  4. Wind-tunnel proven

    We've tested every major competitor in the wind tunnel, and Speed Concept is the fastest. Period.



What people are saying /

Trek’s Speed Concept is one darn fast ride. In fact, it’s the fastest aero bike we’ve ever ridden, and it shaved over a minute off our previous personal best at our local weekday time trial series.
