Gossamer Pro BB386EVO gives high-level performance at a mid-range price. Cold-forged 6061 aluminium crankarms, with a monococque drive-side arm and spider make for durable construction. The BB386EVO spindle can be fitted to a wide range of bikes. For 2014 the Gossamer Pro has been redesigned with a new No Pinch Bolt design for the non-drive-side arm, for an improved connection to the bottom bracket. Ramped and pinned 53/39T chainrings deliver smooth shifts and race-ready gear ratios. The streamlined design of the Gossamer Pro is enhanced by the highly polished gloss anodised finish.
