  • AB oval reduces stress on knees and helps your legs remain fresher for longer
  • You will be able to maintain better cadence while climbing
  • Reduces possibility of leg cramps

IMPORTANT

  • 30T can only work with 46T and special bolt set 46/30. (bolts included with small ring)
  • 32T can only work with 48T and special bolt set 48/32. (bolts included with small ring)
  • No other combination or mix of rings will work. Due to special mounting construction, aesthetic bolt covers are not offered for this design
  • We Only recommend Dura-ace 11spd chain or Sram Eagle 12spd chain for proper clearance of mounting tabs
