The perfect solution when you need something smaller than a 30t on your 104/64 BCD cranks or your 11-speed Shimano XT and SLX 96/64 BCD cranks. Also, they look great when paired with our 104 BCD bash ring on a 104/64 BCD cranksetFits any 104/64 BCD crankset (104 BCD is the middle/big position 64 is the smallest ring position)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 derailmentCompatibilityFits any 104/64 BCD crankset (104 BCD is the middle/big position 64 is the smallest ring position)The Universal Model fits both 104/64 BCD cranksets and the Shimano 11 speed XT M8000 cranks and SLX M7000 cranks.If using a 9-speed drivetrain use a 10-speed chain.
