Made of 4140 carbon steel and hardened black , it has both strength and toughness to easily cope with the challenges of high-intensity racing and complex terrain.
Precise thickening and upgrading: the front diameter is thickened from 5mm to 6mm , while the rear size remains the original , and the transmission structure is precisely optimized.
Super strong torque, thickened design increases cross-sectional area, greatly improves torque capacity, reduces power loss, and the thickened dogbone transmission is more stable.
Center front dog bone 102mm, center rear dog bone 168mm.
