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. 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. The streamlined design of the Gossamer Pro is enhanced by the highly polished gloss anodised finish.
