Tektro Draco hydraulic disc brakes with dual pistons assure precision braking under any conditions
Shimano Alivio 9-speed rear derailleur and Rapidfire trigger shifters for reliable, high-end performance
Shimano crankset with forged alloy arms and Octalink-splined BB interface means greater durability and better shifting performance
Fully butted M4 alloy frame with 29er trail geometry for better control, leverage, and bump performance, plus singlespeed-compatible dropouts and sliders
Custom-tuned 29" SR Suntour suspension fork with hydraulic damping, lockout with lightweight magnesium lowers, and alloy steer deliver the supple ride qualities of a high-end fork
