Five frame sizes with a sensible progression of stack and reach, standover, and head tube height make for an easy-to-select sizing system. The Speed Concept fits the smallest to the tallest athlete. Six stems and more than 14cm of height adjustment per size give the Speed Concept platform more adjustability than a standard road bike. Speed Concept pads and extensions offer a nearly infinite range of adjustability in any direction. Settle in for your best performance.
