BRAKE CABLE Internal brake cable guides for optimal aerodynamics and enhanced visual aesthetics.
TAPERED HEAD TUBE & FORK The head tube is tapered to accept the shape of the tapered fork steerer which measures 1-1/8” at the top of headset and 1.5” at the fork crown. This reduces weight and together with the 1.5” headset boosts front end stiffness. The result is superior handling and steering precision.
DOWN TUBE Extra wide support at the BB shell for maximum BB stiffness.
BB86 The oversize BB shell offers additional torsional stiffness to the frame due to the large contact area between the down tube and the BB shell. Internal Press Fit Bearings also reduce assembled bottom bracket weight.
