Front Chainwheel Ultralight for Road Bike 475U-520
Case hardening process for maximum resistance
Core refined for ultimate strength and hardness
CNC machined for maximum precision
Description
Renthal® Road/ Street Front Chainwheels are CNC machined from 655M13 nickel chromium steel, cased hardened and core refined for durability.
Available in Standard or Ultralight pitches, and with a variety of tooth sizes.
CNC MACHINED
To account for the extremely high tolerances required for engine components, here at Renthal we make use of our in house CNC facilities to accurately machine each individual front chainwheel to the tightest tolerance possible.
CASE HARDENED
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
Core refined 655M13 Nickel-Chrome-Molybdenum alloy steel gives the ultimate combination of strength and hardness.
ULTRALIGHT
Ultralightweight models are available in factory ultralight design to further reduce weight and maximise performance.
