Wolf Tooth Chainrings 32t 76 BCD 9/10-Speed Alloy SRAM XX1 & Specialized Stout

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.Use standard M8 chainring bolts, not the M8.5 bolts included with XX1 spiders. On Wolf Tooth's patented Drop-Stop tooth design provides superior chain retention, wear life and mud-shedding capability.Compatibility:These rings fit any SRAM 76 BCD spider or Specialized Stout crankset. Here are instructions on how to measure your BCD. Threaded for standard M8 chainring bolts. For the XX1 spider, Wolf Tooth recommend the 6mm bolts (or any short M8 chainring bolt). For the Stout crankset Wolf Tooth recommend the 10mm bolts or the bolts that come with the crankset. 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). recommendationsIf you plan to ride in very muddy conditions, Wolf Tooth recommend a chainguide or chainkeeper in addition to a clutch-type rear derailleur. Without these precautions, you may experience chaindrops and/or chainsuckTech Specs:Weight: 32t 51gMaterial: 7075-T6 aluminumMade in the USA
