Innovative design allows very small chainring use on 4x110BCD cranks but a SRAM 12spd or Dura Ace 11spd chain is recommended
Chainrings are sold separately but must be used in 30 46 and 32 48 combinations
Special bolts are included for 30T and 32T inner rings so no additional parts are needed
Inner and outer oval chainrings are optimized with smooth shifting in mind, (6) up-shifting ramps (outer ring), and (12) down-shifting points (outer ring)
Oval rings help the rider spin smoother and generate more power
Example: 32t is equivalent to 30t at deadspot and 34t at the power zone
Works with 2x chainring systems and do not require any modification to the front derailleur for use
Compatibility: Any 4x110BCD Shimano cranks
