76 mm

The Wolf Tooth 76 BCD chainrings work great on any 76 BCD spider or crankset. These will replace the more expensive rings used on SRAM XX1 spiders or other manufacturer's spiders such as Cannondale. Also a great fit on the Specialized Stout crankset. Fits any 76 BCD crankset or spider. 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. Note: Use standard M8 chainring bolts, not the M8.5 bolts included with XX1 spiders. Our patented Drop-Stop tooth design provides superior chain retention, wear life and mud-shedding.
