e*thirteen by The Hive M Profile Guide Ring Chainrings

  • Optimized dual width tooth profiles and chamfers provide greater chain retention than standard rings
  • Exhaustive testing has yielded a long-wearing shape and finish to make sure your chain stays put even after months of use
  • 104bcd rings feature a flip-flop design that allows for a 49mm or 50mm chainline (30t rings use a fixed 47.5mm chainline)
  • Guidering M to fit any 4x104mm BCD crank
  • Dual width "M" (narrow/wide) tooth profile engages the chain securely even at extreme angles
  • 7075-T6 aluminum construction optimized for all chainguide systems to prevent chain jamming
  • 1mm swappable chainline (30t is threaded to accept chainring bolts and does not have this feature)
