Chainrings

Replacement PowerGlide rings for 11 speed crankset. - Compatible with Asymmetrical Yaw front derailleurs - Bolt Circle Diameter (BCD): 110 BCD - Material: Aluminum

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.

SRAM's road chainrings are stamped from 7075 aluminum for low weight and excellent strength. The teeth are ramped for precision shifting, too.

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.

Shimano Ultegra 6800 11-Speed Inner Chainrings - Material: Aluminum - Ring Position/Type: Inner

The all new Turbine 11 Speed rings are ready to ride. Completely redesigned from the ground up, these rings shift like nothing else. The Turbine rings are machined from 7075 aluminum, so they are built to last. Rings are CNC'd from 7075 alloy, creating a ring with instantaneous smooth and quiet shifting, even under load. These 2x rings are super stiff at a minimal weight, resulting in a ring that demonstrates sharp and quick shifts while being highly resistant to impacts.

Wolf Tooth was first to market with Cyclocross 1x specific chainrings because we saw Cyclocross as the perfect use for our Drop-Stop® technology. Since their release, the uses for these rings has expanded beyond Cyclocross to commuting, gravel riding, mountain bikes with 5-arm crank power meters, and even full on-road applications with the giant 50t rings. Fits 110 BCD 5 arm cranksets 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 are for use with 110 BCD 5-arm cranksets. - Stock 2x bolts will not work. You will need bolts like our 6mm bolts which are optimized for single ring mounting. - 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) Recommendations - Recommend the use of a clutch-style rear derailleur for the best chain security. - 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: 34t/44g | 36t/58g | 38t/66g | 40t/74g | 42t/81g | 44t/90g | 46t/107g | 48t/115g | 50t/125g - 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. These chainrings are for Race Face Cinch cranks such as Turbine, Next SL, Sixc & Aeffect. The Wolf Tooth Cinch chainrings feature our patented Drop-Stop® tooth profiles for the best wear life, chain retention and mud clearance. We have optimized tooth profiles for SRAM T-Type Transmission, Shimano Hyperglide+, and all 12, 11, 10, and 9-speed chains. Compatibility - Any Race Face Cinch™ system crankset (including Next SL, Sixc, Turbine, Aeffect) - Riders running SRAM Transmission w/ Race Face Cinch cranksets with a Boost 136/137mm spindle use a Cinch direct mount 0mm offset chainring. - Riders using a Cinch crankset with a Super Boost 151mm spindle use a Cinch direct mount 3mm offset chainring. - Standard (142mm rear hub spacing) 6mm offset, Boost (148mm hub spacing) 3mm offset, and Boost for T-Type Transmission 55mm chainline 0mm offset are available. - Use a 3mm offset chainring for Super Boost applications running standard drivetrains or Transmission. - Wolf Tooth’s patented Drop-Stop® wide/narrow tooth profile for the ultimate chain retention and mud shedding ability. - For 1x9, 1x10, 1x11 and 1x12 drivetrains (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). - Maximum diameter is that of a chainring 2t bigger than the size you order (so be sure there is adequate chainstay clearance!) - Chainline 49mm (standard), 52mm (Boost), 55mm (T-Type Boost) - Available in multiple tooth profiles for optimal performance based on your chain type. Use Drop-Stop ST for use with Shimano 12-speed Hyperglide+ and 12spd KMC chains. Use Drop-Stop A for all 9, 10, and 11spd chains or 12spd SRAM Eagle, KMC, Connex or Wippermann chains. Drop-Stop B is optimized for SRAM 12 spd Transmission (T-type) and Road Flattop chains but is compatible with all chains that work with Drop-Stop A. 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."
