Front Chainwheel Standard for Offroad Bike 304-420
Case hardening process for maximum resistance
Core refined for ultimate strength and hardness
Most used front chainwheel in the world by factory motocross and supercross team
Renthal off-road front chainwheels are chosen by more factory motocross and supercross teams than any other chainwheel on the market today.
They are CNC machined from a cased hardened and core refined 655M13 nickel chromium steel.
The case hardening process ensures that the front chainwheel has the longest service life possible. Each chainwheel is introduced to great heat that hardens the surface.
Core refined 655M13 Nickel-Chrome-Molybdenum alloy steel gives the ultimate combination of strength and hardness.
To account for the extremely high tolerances required for engine components, Renthal makes use of their in-house CNC facilities to accurately machine each individual front chainwheel to the tightest tolerance possible.
