The Factor ONE Integrated Barstem’s stack and reach are affected by the combination of forward and upward sweep of the handlebar, which effectively puts the riders hands in the same location as a conventional bar setup, while reducing the lever length to the shifters.

The bars are designed to mimic the AB02 at the hand position of the rider. All other dimensions such as backsweep, drop depth, bar reach are identical. Simulating the combined stack of the handlebars, dust cover, compression ring, and -6 degree “stem”, the ONE Integrated Barstem puts the handlebar in the identical plane as the equivalent stack OSTRO VAM, simplifying fitting. This is an aggressive, racy fit that nicely serves both fast amateurs and professionals.

Sizes are designated 1, 2, 3, 4, 5, corresponding to stem equivalents of 110 through 150 mm with three high rise options offering an additional 20mm of stack. Up to 15 mm of spacers can be added per bike. When combined with the selection of the three options of high- and low-rise bars, this gives riders 35 mm of shifter stack height range.
