Wolf Tooth 110 BCD Chainring 4-bolt ASYM


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 for 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.

  • These rings are for use with 110 BCD Asymmetric 4-bolt cranks. Here is how to measure your BCD.  
  • Compatible with Dura Ace 9000, Ultegra 6800, 105 5800, Tiagra 4703, and Tiagra 4700
  • Sizes 38T and larger are compatible with Dura Ace 9100, Ultegra 8000 and 105 R7000 but a slight modification is required due to a change in the crank arm profile. The 36T chainring will not work for this modification.  Click here to review the process for the modification, which takes about 5 minutes to perform.
  • Mounts in the big ring position of the cranks but is offset inward for perfect chainline.
  • The stock 2x bolts will not work.  You will need our 6mm bolts which are optimized for single ring mounting.
  • For 1×9, 1×10, 1×11 and 1×12 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).

       Complementing products:

      Chainring bolts  – the stock 2x bolts will not work. You will need our 6mm bolts which are optimized for single ring mounting

      Tanpan – allows Shimano mountain bike rear derailleurs to be used with Shimano road shifters

         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! Without these precautions, you may experience chaindrops and/or chainsuck.

            38t = 66g
            40t = 74g
