The Pursuit Special is All-City's addition to the pantheon of high end track chainrings. They were designed in house by track racers for track racers and are optimized for weight, stiffness, and engagement. These beauties are cnc’d in the USA and utilize a proprietary tooth profile for smooth and quiet operation. The 49-52’s utilize a solid body design with reliefs in the back for weight savings, while the 46-48’s have full cutouts. In sticking with the theme of their aluminum track bike, the Thunderdome, All-City named these rings after Mad Max’s car, the Pursuit Special. - Material: 7000 Series Aluminum - Ring Position/Type: Single

These CNC’d lovelies will work just fine in a multi-ring setup, but they’re not equipped with shift ramps or pins, which makes them perfect for single-ring drivetrains. - Longevity, performance, and quiet operation - Material: CNC-machined 7075-T6 Aluminum - Chain Compatibility: 8-, 9-, or 10-speed compatible

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 2.1mm thick so they work well with 9-speed chains.

Trust Surly to come up with a reasonable solution to a bizarre problem. The Surly MWOD chainring set moves a bike's chainline away from the spinning tire allowing for the use of super wide tires on extra wide rims. The genius part is that it doesn't increase the Q factor (a.k.a. width of the bottom bracket) and keeps the low gears necessary for pedaling bikes with monster tires. The chainring set bolts directly to Mr. Whirly cranks and is available in two sizes.

This aluminum bash guard is compatible with Surly's MWOD cranksets. Keep rocks and roots away from your chainring teeth and ride on.

Surly's MWOD Inner Chainrings are made from stainless steel for extreme durability. These rings are compatible with Surly's MWOD cranks.

Surly's MWOD chainrings convert your Mr. Whirly crankset into an offset mountain double crank. In simple terms, they allow your fat bike to run an extra wide rear tire and rim combo (for example, 4.7-inch tires on 100mm rims or 82mm rims on your Pugsley) while avoiding chain-on-tire rub. This outer chainring bolts directly to the inner ring with four chainring bolts.

- Fits asymmetrical 96mm BCD with built-in threaded standoffs - Used on Shimano XTR M9000 and M9020 crankset (both race and trail models) - Features Drop-Stop tooth design to prevent unwanted chain drop - Mount using the stock Shimano XTR M7 chainring bolts - 49mm chainline for 28-34 tooth and 50mm for 36 tooth - Recommended for use with 10 or 11sp chain (10sp chain works on 9sp drivetrain) - Made in the USA from 7075-T6 aluminum alloy - 41g (30t)

120 BCD cranksets were introduced with SRAM 2x10 drivetrains and are excellent candidates for a 1x conversion with our patented Drop-Stop chainrings. These rings will allow you to convert your 120 BCD crankset, like the SRAM XX and others, to a 1x application! - These rings fit any 120 BCD crankset or spider - For SRAM cranksets you must use the stock M8.5 bolts. These are not standard bolts and Wolf Tooth's bolts will not work with this chainring. Note that only about 3 threads will engage (same with the stock SRAM rings) - For the 36t chainring and non-SRAM cranksets you will need the M8.5 bolts from Wickwerks if your crankset doesn't already have them. These bolts actually have more threads engaged and will work better than the SRAM ones. - 36t is the smallest number of teeth that fits on a 120 BCD - For 1x9, 1x10, 1x11 and 1x12 drivetrains (including SRAM Eagle) - Compatible with all 10, 11, and 12 speed chains (Including SRAM Eagle) - 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).

This 94 BCD 5 bolt ring will serve all your Vintage crankset and Surly crankset needs! - 4 of the holes are threaded and 1 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 - 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 from problem solvers. - This ring will work with your vintage 94 BCD 5-bolt cranksets!! - For 1x9, 1x10, 1x11 and 1x12 drivetrains (including SRAM Eagle) - Compatible with all 10, 11, and 12 speed chains (Including SRAM Eagle) - 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). - Provide a great chainline on most boost bikes.

- Cyclocross ring with Drop-Stop tooth design to prevent unwanted chain drop - Recommended for use with 10 or 11sp chain (10sp chain works on 9sp drivetrain) - Designed and manufactured in the USA from 7075-T6 aluminum alloy

The XTR M960, now 4 generations old in the XTR lineage, is an oldie-but-goodie crankset and Wolf Tooth aims to meet your 1x needs with these rings. Compatibility: - These rings only fit on the M960 crankset in the middle ring position. They are a 102mm BCD. - For 1x9, 1x10, 1x11 and 1x12 drivetrains (including SRAM Eagle) - Compatible with all 10, 11, and 12 speed chains (Including SRAM Eagle) - 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)

Wolf Tooth's SDM chainrings replace your existing spider and chainring with one clean looking, light weight, and stiff piece of machined billet. These come in 3 different offsets: standard GXP, Boost and BB30. Compatibility: - These direct mount chainrings will replace your 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 Wolf Tooth SDM® chainring. There are 3 offsets: - Standard: 47mm chainline, 6mm offset for cyclocross and road cranks - Standard: 49mm chainline, 6mm offset for GXP and long spindle BB30 - Boost: 52mm chainline, 3mm offset - BB30: 49mm chainline, 0mm offset for BB30 short spindle cranks - Fat Bikes: If you are planning to use this on an X9 or XX1 fat bike crankset with a 190/197 rear hub spacing use the 0 offset ring. If your fat bike has a 170/177 rear hub spacing, use the Standard 6mm offset - If you have a BB30 crankset (30mm diameter Aluminum Spindle) this measurement will determine whether it is a long or short spindle:

An issue many people ran into when they began using 1x setups was chain retention with the front chainring. In the beginning of the 1x movement, many companies dealt with this by using aftermarket chain keepers that somehow bolted to the frame. Many people discovered that using a narrow-wide chainring in conjunction with some type of 'clutch' rear derailleur helped abate or eliminate these chain-jumping issues. Narrow-wide rings use alternating tooth profiles that more positively engage the chain and help control a deflecting chain in bumpy conditions. Your friends at Surly have partnered with SRAM to bring you stainless steel X-Sync chainrings. Stainless Steel is durable. This durability is pretty useful when you're talking about the one ring that is bearing the brunt of all your miles.

The new chainrings are stainless steel and have improved ramps, gates, and pins for better shifting performance.

This Surly OD Chainring is made of aluminum, has pins and ramps for smoother shifting, and comes in always-stylish black.
