AbsoluteBlack Premium 2x SUB-Comp Oval Chainring - 4 x 110mm BCD, 48T, Outer (Black)

Features:

• Innovative design allows very small chainring use on 4x110BCD cranks but a SRAM 12spd or Dura Ace 11spd chain is recomended
• Chainrings are sold seperately 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
• Designed in UK, manufactured in Poland
• Speed: 2x9/10/11spd
• Arm x BCD: 4x110mm Asymmetrical
