  • The front suspension features 32mm Cr-Mo stanchions and a smooth 80mm of coil-sprung travel, rebound and preload adjustments, and lockout.
  • The Specialized 3D-forged alloy stem is stiff and strong and features an oversized 31.8mm bar-clamp area for precise steering.
  • Tektro’s Auriga Comp dual-piston hydraulic disc brakes feature smooth lever action and easy-to-control stopping power.
  • Shimano’s Deore rear derailleur uses a wide-link parallelogram design for increased rigidity, which means accurate shifting and long life.
  • Shimano’s Deore Rapidfire trigger shifters feature Dual Control for extra-fast shifts from thumb and/or forefinger.
  • The triple-chainring crankset features Shimano’s splined Octalink bottom-bracket connection, which gives maximum power transfer smooth pedaling action.
  • The triple-chainring crankset features Shimano’s splined Octalink BB connection, which gives maximum power transfer and smooth pedaling action.
