With a unique shape and ride-tune, the AM30 balances compliance and vibration damping for all-day comfort, while retaining quick cornering, acceleration, and gravity-rated strength. Offset spoke holes balance spoke tensions to help preserve the wheels' quickness and the spoke's integrity - despite the rim's additional compliance.Wide Hookless Bead dissipates impact energy preventing the rim from slicing the tireMolded Spoke Holes for more reliable wheel buildsMolded conical seats allow the nipples and spokes to articulate, preventing premature fatigue and failureAsymmetric spoke holes for more balanced spoke tensions30mm internal rim width supports 2.3 - 2.6" tires.
