Bought this new for a build I am doing and come to find out it was one too many teeth on the ring. Never installed chain just did a dry fit on the frame and it was too big. Need to sell to buy a smaller crankset. Unidirectional carbon fiber arms and aluminum chainring spider provide excellent strength-to-weight. X-Glide tooth profiles and shift assist pins enable quick and reliable front shifting. Product Details:
"Hidden" chainring bolt threads into crank arm to enhance chainring stiffness
