DH / Freeride / All Mountain Chromag utilizes the 35mm clamp size to create a wider, stronger bar in the same weight class as its 31.8 counterpart - the Fubars OSX. The OSX 35 is made from 7000 series aluminum. It provides the best strength to weight ratio possible. This is a strong bar best suited to DH/Freeride or trail riding. At 800mm it is our widest aluminum bar. Same perfect fit as the original OSX, with 25mm rise, 5-degree upsweep and 8-degree back sweep.
