Wolf Tooth was first to market with Cyclocross 1x specific chainrings because we saw Cyclocross as the perfect use for our patent pending Drop-Stop technology. These beautifully machined 110 BCD Asymmetric 4-bolt chainrings are optimized to be compatible with your 1x Shimano CX/ Road/ Gravel drivetrain whether you run Dura Ace 9000, Ultegra 6800, 105 5800, or Tiagra 4700. They are also offset for the ideal 1x chainline. Compatibility: * These rings are for use with 110 BCD Assmetric 4-bolt cranks. * Compatible with Dura Ace 9000, Ultegra 6800, 105 5800, Tiagra 4703, and Tiagra 4700 * Mounts in the big ring position of the cranks but is offset inward for perfect chainline. * For 1x9, 1x10, 1x11 and 1x12 drivetrains including SRAM Eagle (TM) * * Compatible with all 10, 11, and 12 speed chains including SRAM Eagle (TM) * If using a 9 speed drivetrain use a 10 speed chain (shifts and works well on a 9 speed drivetrain and fits the ring tighter for better chain retention). * Tech Specs: * Design and manufactured in the Minneapolis, MN USA * Wolf Tooth’s patent pending Drop-Stop wide/narrow tooth profile for the ultimate chain retention and mud shedding ability * * Recommend the use of a clutch style rear derailleur for the best chain security. * Material 7075-T6 * Colors - black * Chainline - 47.5mm * If you plan to ride in very muddy conditions, we recommend a chainguide or chainkeeper in addition to a clutch-type rear derailleur!
