Wolf Tooth 120 BCD Chainring – 36t, 120 BCD, 4-Bolt, Drop-Stop A, Black

120 BCD cranksets were introduced with SRAM 2x10 drivetrains and are excellent candidates for a 1x conversion with our patented Drop-Stop chainrings. These rings will allow you to convert your 120 BCD crankset, like the SRAM XX and others, to a 1x drivetrain. . 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. Compatibility These rings fit any 120 BCD crankset or 4-bolt spider. You must use M10x.75 bolts with a shoulder on them. These are not standard bolts and Wolf Tooth's.
