Chainrings

The 102BCD chainring was made specifically for the XTR M960 crankset - Only fits on the M960 crankset in the middle 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 derailment Compatibility: - These rings only fit on the M960 crankset in the middle ring position - 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) - 6mm chainring bolts needed - Chainline: 50mm - Use Drop-Stop A 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. - NOT compatible with 12spd SRAM Transmission (T-Type) Flattop, 12spd Shimano HG+, or 12spd Campy Recommendations - If you plan to ride in very muddy conditions, try using 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: 32t/47g - Material: 7075-T6 aluminum

The Wolf Tooth 107 BCD Chainring for SRAM Cranks is compatible with most new SRAM 1x road cranks that use the 107 BCD spider, including the SRAM AXS Power Meter Spider. This chainring uses the patented Wolf Tooth Drop-Stop B Wide/Narrow tooth profile that is optimized for drop bar bikes. - Fits 107 BCD for SRAM Cranks - Drop-Stop technology prevents dropped chains. 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 while reducing friction. - Cranks that use the 107 BCD spider also use the SRAM 8-bolt interface, which is compatible with Wolf Tooth Direct Mount Chainrings for SRAM 8-Bolt 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. - 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 (like our GnarWolf) 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. Tech Specs: - Material: 7075-T6 aluminum - Weight: 38t/75g | 40t/78g | 42t/86g - Made in the USA

These nickel-plated chainrings were designed to look great on the Cane Creek eeWing titanium cranksets. They also work great on SRAM direct-mount cranksets. The Shimano XTR, XT, and SLX 12spd Hyperglide+ chain works differently than other products on the market so Wolf Tooth engineers developed a completely new tooth profile to provide optimal chain retention and durability when using this new chain technology. - The new HG+ chain interacts with the chainring much differently than a traditional wide/narrow design. Wolf Tooth engineers spent the time to understand how the system works and design a new tooth profile that is optimized for this system. - Engineered proprietary tooth profile maintains the quiet and smooth performance of the HG+ drivetrain with legendary Wolf Tooth chain retention. - Prevents premature ring and chain wear that can come from non-optimized profiles. 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.

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 - Boost 3mm offset

Designed specifically for use e-mtb drive systems, SRAM’s XX T-Type direct-mount rings offer light weight with optimal retention performance needed for e-mtb. - Steel and Aluminum construction

Mud and moving parts are enemies in the sport of cyclocross. That's why SRAM decided they were going to simplify things. Remove the front derailleur, increase the range of the cassette, make dropped chains a thing of the past, and you've got a cross drivetrain worthy of hammering. SRAM's CX1 X-Sync Chain Ring is an integral part of that system. It mates to 110 BCD cranks and features a wide-narrow-wide tooth profile to securely hold the chain through the roughest terrain. It's also specially designed with mud clearing in mind to keep your rig light and fast. A variety of sizes ranging from the spin-to-win 38T to the flat-out 46T let you dial in your rig for your strengths or course.

Direct mount chainrings for SRAM cranks with 8-bolt mounting replace your existing spider and chainring with one clean-looking, lightweight, and stiff piece of machined billet. 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.

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 direct mount chainrings will replace your existing chainring and spider or replace the direct mount chainring for SRAM AXS cranksets and other cranks that use the 8-bolt mounting. Most SRAM cranksets have traditionally used a 3-bolt mounting, but the 8-bolt mounting has always been used on the Quarq power meter cranks. Now some non-power meter cranks like SRAM AXS use the 8-bolt mounting. - All SRAM Direct Mount DUB road cranksets use the 8-bolt mounting standard. These cranksets use either 107 BCD or 94 BCD; any of those cranksets with a removable spider use the 8-bolt mount. - Wolf Tooth's patented Drop-Stop® wide/narrow tooth profile for the ultimate chain retention and mud-shedding ability - 6mm offset - Chainline 45mm - 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.

Engingeered to interface with Bosch motor systems, SRAM drivetrain engineers optimized this ring to combat the high-torque, high-wear situations e-bike riders face. The aggressive T-Type tooth design provides better chain retention for a smoother, more efficient pedal feel with a focus on long wear-life. - Steel (36T,38T). - AeroGuard Compatible that fufills EN 15194:2017 standard - Backwards compatible with other Eagle Technology.

Surly's Stainless Steel Chainrings last longer than their aluminum brethern because the 304 grade metal they use is 35% stronger. The rings aren't pinned or ramped so when one side starts to wear you can flip it around and pedal some more! They work great with singlespeed, fixed, and 1x9 applications, and the teeth are 2.2 - 2.3mm thick so they work well with wider chains.

These 102 BCD rings fit Shimano XTR M960 -- they cannot be used on any other crankset! Only purchase this chainring if your crankset looks like the one in the photo on this page. Color: Black Rings have 50mm chainline. All chainrings feature our Drop-Stop tooth design and are made from 7075 Aluminum. Use a 10 or 11 speed chain. If using a 9 speed drivetrain, plan to use a 10 speed chain (it will shift fine), as the 9 speed chain fits too loosely on the ring. *** Be sure to order a colorful set of Wolf Tooth chainring bolts to go with you new ring! Order the 6mm (short) bolt+nut combo. ***

These fit all common cranksets using 104 BCD mounting. See this WTC Tech Document if you have a Shimano Double M785 XT or M665 SLX double crankset Note that the 30T chainring is threaded and has a 48 mm chainline. All other rings have 50mm chainline. All chainrings feature our Drop-Stop tooth design and are made from 7075 Aluminum. Use a 10 or 11 speed chain. If using a 9 speed drivetrain, plan to use a 10 speed chain (it will shift fine), as the 9 speed chain fits too loosely on the ring. Be sure to order a colorful set of Wolf Tooth chainring bolts to go with your new ring! For the 30T order our 10mm (long) bolts and all other sizes order the 6mm (short) bolt+nut combo. Color: Black Product Weights: 30t - 36g, 32t - 47g, 34t - 56g, 36t - 60g, 38t - 66g

Color: Black 110 mm BCD chainrings to fit standard cranks with 5 bolt, 110 mm spiders. Does NOT fit on the cranksets for Shimano DA 9000 / Ultegra 6800. They WILL work with 11 speed chains. Strongly recommend a 10 or 11 speed chain. If using a 9 speed drivetrain, plan to use a 10 speed chain (it will shift fine), as the 9 speed chain fits too loosely on the ring. *** Be sure to order a colorful set of Wolf Tooth chainring bolts to go with you new ring! Order 6mm (short) bolt+nut combo. *** Note on mud: wide/narrow chainrings do no work well in heavy mud (Wolf Tooth or any other brand) if you plan to ride in very muddy conditions, we recommend a chainguide or chainkeeper and clutch-type rear derailleur! Without these precautions, you may experience chaindrops and/or chainsuck. All chainrings feature our Drop-Stop tooth design and are made from 7075 Aluminum. Use a 10 or 11 speed chain. If using a 9 speed drivetrain, plan to use a 10 speed chain (it will shift fine), as the 9 speed chain fits too loosely on the ring. Product weights: 36t - 58g, 38t - 66g, 40t - 74g, 42t - 81g, 44t - 90g

Color: Black 130 mm BCD chainrings to fit standard cranks with 5 bolt, 130 mm spiders. Does NOT fit on the cranksets for Shimano DA 9000 / Ultegra 6800. They WILL work with 11 speed chains. Strongly recommend a 10 or 11 speed chain. If using a 9 speed drivetrain, plan to use a 10 speed chain (it will shift fine), as the 9 speed chain fits too loosely on the ring. *** Be sure to order a colorful set of Wolf Tooth chainring bolts to go with you new ring! Order the 6mm (short) bolt+nut combo. *** Note on mud: wide/narrow chainrings do no work well in heavy mud (Wolf Tooth or any other brand) if you plan to ride in very muddy conditions, we recommend a chainguide or chainkeeper and clutch-type rear derailleur! Without these precautions, you may experience chaindrops and/or chainsuck. 38T important note: The chain will contact the spider arm slightly when using the 38T chainring (see photo below). We recommend filing a small chamfer on the spider arm but you can also just install it and let the chain do the work. This is only an issue with the 38T as the 130 BCD was designed for 39T smallest ring. All chainrings feature our Drop-Stop tooth design and are made from 7075 Aluminum. Use a 10 or 11 speed chain. The only brand of chain we don't recommend is Wippermann. Product weights: 38t - 52g, 40t - 60g, 42t - 62g, 44t - 79g

You asked for it, we made it -- the Wolf Tooth GC is now available in a slightly smaller size! Most of the low gearing from its big brother with improved shifting in the smaller cassette cogs. Be sure to check out the GC tech page for more details This cassette sprocket is only for use with Shimano brand 10spd XT & XTR cassettes. It is NOT compatible with any other brand or model of cassette. The shift points are properly timed to the tooth locations on the 36T Shimano cogs for optimal shifting performance. Use of this cassette sprocket requires removal of the 17T or 15T cog & spacer from your cassette. Note on “B-screw”: We have found a longer screw is almost never needed with SRAM derailleurs and only needed for about 50% of Shimano derailleurs. We have added it as a separate item in our accessories category. If you think you might need the longer screw, order one separately or just go to your local hardware store and pick up an M4 x 25 socket head cap screw. You may need a longer chain than what is presently on your bike. Make sure that when shifted to the 40T cog, there is still some amount of forward travel possible with the rear derailleur cage. This is especially important on bikes with rear suspension. We have tested with Shimano, KMC & SRAM chains – all function well. Compatible only with the following Shimano 10spd cassettes XT 11-36t (CS-M771) XTR 11-36t (M980) Not compatible with SLX 11-36 cassettes because the 17t cog cannot be removed. Note: unlike the 42T, the GC 40T will usually work with 2011 or older SRAM rear derailleurs. We cannot guarantee it on all bikes however. Weight 79g

The GC42 cassette cog is so big that when machining the first batch, the machinist thought he made a mistake! If being big is cool then the GC42 cassette cog is the coolest cog around. This cog is made with the precision and finish our customers have come to expect from WTC, and this enables quite possibly the best feeling shift in the cassette. Be sure to check out the GC tech page for more details This cassette sprocket is only for use with Shimano brand 10spd XT & XTR cassettes.

Weight 86g Note: the GC 42 is not compatible with 2011 or older SRAM rear derailleurs due to the location of the upper jockey wheel. It is difficult or impossible to get satisfactory shifting with the 2011 or older SRAM rear derailleurs so we do not recommend using the GC 42 if you have one of these. The GC 42 works great with the newer SRAM rear derailleurs however.

The best ways to tell the vintages of your rear derailleur is 1) If you have a type 2 (clutch type) rear derailleur it is 2012 or newer and 2) the upper jockey wheel on 2012 and newer rear derailleurs are offset from the derailleur cage's axis of rotation. It is difficult and sometimes impossible to get satisfactory shifting with the 2011 or older SRAM rear derailleurs so we do not recommend using the GC 42 if you have one of these. The GC 42 works great with the newer SRAM rear derailleurs however.

Color: Black These bash rings attach directly to our direct mount Drop Stop chain rings. These are designed for XC, trail and enduro riding. They are not meant for downhill use where heavy impacts are expected. You will need short (6mm long) chainring bolts/nuts to mount the 28T-36T bash rings (we recommend the Wolf Tooth ones sold here on our store). The 24/26T bash ring includes M5 mounting bolts. *** Note: These will not fit any other chainring or spider -- only Wolf Tooth SRAM direct mount! *** Made from 7075-T651 aluminum. Product weights: 24/26 - 44g, 28/30 - 47g, 32/34 - 50g

Color: Black These can also be used on a BB30 / PF30 long spindle crankset -- the 3rd product picture shows you how to determine if you need this ring or the Short Spindle BB30. This SDM ring is dished in ~6mm, whereas the BB30 short spindle ring is flat. These are Direct Mount chainrings for SRAM GXP crank. This will replace you existing chainring and spider, which is attached via 3 bolts on the back side of the spider near the spindle. You will use these same 3 bolts to attach the SDM ring. SDM chainrings fit on SRAM S2200, S2210, X9, X0, X01, XX1, Truvativ AKA Cranksets (GXP version) only. Newer S1400 (or X7) cranksets with removable spiders will work with SDM rings. Older versions of these cranksets may not have removable spiders. If the crankarm and the spider are all made from the same piece of aluminum it is not removable. Chainline is 50mm on all rings (on a GXP or BB30 long spindle crankset). All chainrings feature our Drop-Stop tooth design and are made from 7075 Aluminum. Use a 10 or 11 speed chain. If using a 9 speed drivetrain, plan to use a 10 speed chain (it will shift fine), as the 9 speed chain fits too loosely on the ring. Product weights: 26t - 53g, 28t - 60g, 30t - 68g, 32t - 74g, 34t - 83g, 36t - 90g

We think these bolts the best on the market. They have a 5 mm hex socket and are 10 mm long so you can use a bash ring with your 30T x 104 chainring. The bolt length is laser engraved on the head to avoid confusion with shorter bolts. Simply better. No nuts are included with these bolts because the 30t x 104 chainring has threaded standoffs. These work great with Wolf Tooth or any other brand threaded M8 x 0.75 chainrings. Designed and manufactured in the USA from 7075-T6 aluminum alloy. Torque: 6-7 N-m MAX with light grease on the threads only. Product weight - 4 bolts = 4g

We think these bolts and nuts are the best on the market. Other short bolts/nuts designed for single rings use a slotted nut that is likely to strip-out the first time you use it. Ours use a large hex socket on both the bolt (5 mm) and the nut (6 mm). Bolts are 6 mm long and have the length laser engraved on the head. Simply better. These work great with Wolf Tooth 5 bolt rings or any other brand 5 bolt single chainrings. Designed and manufactured in the USA from 7075-T6 aluminum alloy. Torque: 6-7 N-m with light grease on the threads only. Product weight: 5 bolts = 9g
