Wolf Tooth 110 BCD Gravel / CX / Road Chainrings
From $136.99
Drop-Stop A
120 BCD cranksets were introduced with SRAM 2x10 drivetrains and are excellent candidates for a 1x conversion with our patented Drop-Stopchainrings. These rings will allow you to convert your 120 BCD crankset, like the SRAM XX and others, to a 1x drivetrain.
Drop-Stop B
Wolf Tooth was first to market with Cyclocross 1x specific chainrings because theysaw Cyclocross as the perfect use for theirDrop-Stop technology. Since their release, the uses for these rings has expanded beyond Cyclocross to commuting, gravel riding, mountain bikes with 5-arm crank power meters, and even full on-road applications with the giant 50t rings.
Features
Drop-Stop A
Fits 120 BCD cranksets or 4-bolt spiders
Drop-Stop technology. On Wolf Tooth's 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
Drop-Stop B
Fits 110 BCD 5 arm cranksets
Drop-Stop technology. On Wolf Tooth's 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.

| Compatibility | These rings fit any 120 BCD crankset or 4-bolt spider. For SRAM cranksets you must use the stock M10x.75 bolts with a shoulder on them. These are not standard bolts and Wolf Tooth's bolts will not work with this chainring. Note that only about 3 threads will engage (same with the stock SRAM rings) SRAM is the only supplier of the M10 x .75 bolts 36t is the smallest number of teeth that fits on a 120 BCD 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). Chainline - 51mm for 36t and 52mm for 38t (38t is wider for more chainstay clearance) | These rings are for use with 110 BCD 5 arm cranksets. Stock 2x bolts will not work. You will need bolts like our 6mm bolts which are optimized for single ring mounting. Chainline - varies - these rings can be mounted in either the big or small ring position on a double cranksets. The most common mounting is in the big ring position because of chainstay clearance. The ring centerline is ~2mm from the ring's mounting face so they usually sit about 2mm closer to the frame than the stock big ring (depends on the stock ring) |
