Wolf Tooth was first to market with cyclocross 1x specific chainrings because we saw cyclocross as the perfect use for our patent pendingDrop-Stoptechnology. These beautifully machined 110 BCD asymmetric 4-bolt chainrings are optimizedfor your 1x Shimano CX / road / gravel drivetrainwhether you runDura Ace 9000, Ultegra 6800, 105 5800, or Tiagra 4700.They are alsooffset for the ideal1x chainline.

• Fits 110 BCD Asymmetric 4-bolt Shimano cranks

• Drop-Stop technology. On Wolf Tooths patented wide/narrow chainring, the wide side of the tooth has maximum contact on the drive side which spreads the load and improves chainring life. The narrow side allows clearance for mud and debris which reduces friction.

• Alternating wide/narrow tooth pattern prevents chain derailment

Compatibility

• Fits 110 BCD asymmetric 4-bolt cranks
• All sizes compatible with Dura Ace 9000, Ultegra 6800, 105 5800, RS510, Tiagra 4700 or 4703,Sora R3000 or R3030, andClaris R2000 or R2030 cranks.

• Size 42t and larger will work with theDura Ace 9100 power meter
• 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 our6mm boltswhich are optimized forsingle ring mounting.
• If using a 9-speed drivetrain use a 10-speed chain. It fits tighter for better chain retention
• Chainline 47.5mm

Recommendations

• Recommend the use of a clutch style rear derailleur for the best chain security.
• 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.
