Ultralight Steel Front Sprocket | Standard (520-15t) - 520 Conversion

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.
