• Fewer gears mean larger teeth to index
  • Larger indexing teeth equal less wear and tear
  • Less shifting extends shifter life
 
  • Fewer gears mean less derailleur travel and better chainline
  • Less travel and better chainline equal less wear and tear
  • Less shifting extends derailleur life
  • Fewer gears mean wider spacing and easier set-up
  • Combined with better chainline equal less wear and tear
  • 9 cogs weight less than 12
 
  • Unique geometry allows for thicker side plates than 12-speed drivetrains
  • Internal dimensions that are compatible with modern Wide / Narrow chainrings
  • Resists stretching over time increasing shifting performance
