  • Innovative design allows very small chainring use on 4x110BCD cranks but a SRAM 12sp or Dura Ace 11sp 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 dead spot and 34t at the power zone
  • – Works with 2x chainring systems and does not require any modification to the front derailleur for use
  • – Compatible with crank models: Shimano Dura-Ace 9100, R9120, R9150 & R9170 Di2, Ultegra 8000, R8020, R8050 & 8070 Di2., 105 R7000, R7020, R7070, Dura-Ace 9000 & Di2, Ultegra 6800 & Di2, Shimano 105 5800. Not compatible with Power2max
  • – Designed in UK, manufactured in Poland
