The profile of the teeth is designed with Ultra-Drive™ geometry which facilitates the passage of the chain on the sprockets and makes shifting precise, fast and silent.
- Heat treated cogs are carefully machined from nickel chrome steel
- All of these cogs have a hardened chrome, satin silver finish for longer wear
- Each cog has an indented ramp, called Ultra Drive (UD), to assist in up shifting
- Tooth profiles are also custom configured to help with down shifting.
