Eagle Technology creates the smoothest, quietest, longest-lasting, and most efficient drivetrains we've ever made. The radical new look and feel of our X-SYNC 2 Eagle chainring is a direct result of SRAM drivetrain engineers studying the performance and wear characteristics of thousands of X-SYNC chainrings. The longer, positive-rake tooth shape has been designed to work perfectly with the new Eagle chain to increase chain retention and overall pedaling efficiency, while decreasing friction, noise, and wear. - X-SYNC 2 chainring design increases chain retention, wear life, and reduces friction and noise. - Designed to be used with Eagle chain - Non-Boost 6mm offset

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 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, we recommend the 6mm bolts (or any short M8 chainring bolt). For the Stout crankset we 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). Use Drop-Stop A or B for all 9, 10, and 11spd chains or 12spd SRAM Eagle, KMC, Connex or Wippermann chains DROP-STOP A Wolf Tooth Drop-Stop A is the original patented wide/narrow chainring compatible with multiple drivetrain brands including 9, 10, 11, and 12spd SRAM Eagle, KMC, Wippermann, etc. Recommendations If you plan to ride in very muddy conditions, we recommend a chainguide or chainkeeper in addition to a clutch-type rear derailleur. Without these precautions, you may experience chaindrops and/or chainsuck Tech Specs: - Weight: 30t/45g | 32/51g - Material: 7075-T6 aluminum - Made in the USA

More power, better traction, less shifting. Wolf Tooth oval chainrings use our proprietary PowerTrac design that has all the benefits of oval, but without the funky, uneven pedal stroke. Ride one once and you'll wonder why you waited so long to try oval. Think of an oval chainring as two chainrings in one. A major benefit of oval is how the shape of the chainring alters your gearing in two important phases of your pedal stroke by harnessing your body's natural biomechanics. Here's how it works. The area of the chainring with the larger diameter engages with the chain at the optimal point on the downstroke, which is what's known as the Power Zone. If you were to look at a clock, the Power Zone would be between 1-5 and 7-11. Conversely, the Recovery Zone – back to the clock face, between 11-1 and 5-7 – is the weakest part of the pedal stroke, when the oval maximizes your efficiency. A 34T oval chainring behaves like a 36T chainring when you want power, while behaving like a 32T chainring when you're climbing. We've also engineered our oval chainrings to provide smoother, more efficient pedal rotation. This equates to better traction because of steadier torque on the rear wheel. With a Wolf Tooth oval chainring, you can harness more of your strength in the Power Zone, while having easier pedaling in the Recovery Zone. Compatibility: - These rings are for use with 110 BCD 5 arm cranksets. - Crank arm clocking arrow will be rotated 180 degrees from normal on cranksets that have 4 bolts visible and 1 hidden bolt behind the crank arm like for SRAM. - Wolf Tooth's patented Drop-Stop® wide/narrow tooth profile for the ultimate chain retention and mud shedding ability - 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) - Can be mounted in either the big or small ring position of a double crankset given chainstay clearance in the small ring position. - Stock 2x bolts will not work. You will need bolts like our 6mm bolts which are optimized for single ring mounting. - Use Drop-Stop B for all SRAM Eagle, SRAM Road and Transmission (T-Type) Flattop chains, 9, 10, and 11spd chains or 12spd KMC, Connex, Wippermann, Campagnolo. DROP-STOP B - Compatible 9, 10, 11, and 12s SRAM Eagle, 12s SRAM Transmission (T-type) Flattop, 12s Campy, 12s KMC - Not compatible with 12s Shimano HG+ chains Recommendations - - If you plan to ride in very muddy conditions, we recommend a chainguide or chainkeeper in addition to a clutch-type rear derailleur! Without these precautions, you may experience chaindrops and/or chainsuck. - Recommend the use of a clutch style rear derailleur for the best chain security.

This 94 BCD 5-bolt ring will serve all your Vintage crankset and Surly OD crankset needs. - Fits any 94 BCD 5-bolt crankset (modification may be needed) - 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: - Four of the holes are threaded and one is a normal through bolt hole (done for Surly compatibility). Use a stock 10mm chainring bolt for the fifth, hidden arm. - These rings fit any 94 BCD 5 bolt crankset (possible alterations needed to fit some crankarms) - For Plus size bike applications with the Surly OD crankset, e.g. Instigator and Krampus, you will need to use the stock spacers (Spacer Kit QBP Part number CR8609) that came with your 1x setup. You will also need some 16mm bolts which can be purchased from Problem Solvers. - 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). - Provides a great chainline on most boost bikes. - Chainline (approximate as BB centering and cranksets vary) DROP-STOP A Wolf Tooth Drop-Stop A is the original patented wide/narrow chainring compatible with multiple drivetrain brands including 9, 10, 11, and 12spd SRAM Eagle, KMC, Wippermann, etc. Recommendations If you plan to ride in very muddy conditions, we recommend a chainguide or chainkeeper in addition to a clutch-type rear derailleur.
