Chainrings

The EX1 drive train was designed specifically for the demands of electric-assist mountain bikes: a wide gear range with bigger jumps between gears and sturdy components to handle higher torque loads. Liberal use of features found on SRAM’s high end MTB parts provide high value, quiet operation and ease of service. - X-Sync (wide-narrow) tooth profiles for great chain management - Compatible with Bosch mid-drive E-bike systems - Material: Steel - Size/BCD: Direct mount - Recommended Group: EX1

It’s undeniable that some riders’ pedaling styles benefit from oval chainrings, so SRAM has engineered the new X-SYNC 2 Oval chainrings to give them the advantage they want. They are the only oval option available with SRAM's genuine X-SYNC 2 teeth profile, so they are the only oval chainrings on the market that are 100-percent optimized for Eagle. - Direct Mount Type: Direct Mount SRAM - Drivetrain Speeds: 10, 11, 12 - Material: Aluminum - Ring Position/Type: Chain Retaining Single Ring - Chainline/Hub Compatibility: 135/142 MTB Hubs, 150/157 DH Hubs, 170/177 Hubs

Tall teeth with alternating tooth profiles hold the chain amazingly well and still provide space for mud to clear. - Full CNC Aluminum rings - Ring Position/Type: Chain Retaining Single Ring - Drivetrain Speeds: 10, 11 - Chainring BCD: 110 SRAM Asymmetric

SRAM's X-Sync Boost Direct Mount Chainring features tall teeth with alternating tooth profiles that hold the chain amazingly well and still provide space for mud to clear. - Chainring BCD: SRAM BB30 Direct Mount, SRAM GXP Direct Mount - Color: Black - Drivetrain Speeds: 10, 11 - Material: Aluminum - Ring Position/Type: Chain Retaining Single Ring - Offset: 3mm

Original equipment on SRAM and Truvativ cranks, these chainrings also work well with other drivetrains.

SRAM's X-Sync 11-speed chainring features tall teeth with an alternating tooth profile to hold the chain amazingly well and still provide space for mud to clear. - Drivetrain Speeds: 10, 11 - Material: Aluminum - Ring Position/Type: Chain Retaining Single Ring

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.

Original equipment on SRAM and Truvativ cranks, these chainrings also work well with other drivetrains.

Tooth shapes and shift pins are designed specifically for use with SRAM Yaw front derailleurs. - Compatible with the SRAM Red Yaw front derailleur - 7000 series aluminum provides strength and durability - Non-Hidden Bolt rings fit other SRAM 10-speed crank arms - Ring Position/Type: Outer - Drivetrain Speeds: 10 - Chainring BCD: 130

A tight and consistent 13-tooth gap between chainrings delivers accurate and dependable shifting and is the core of our X-Range gearing. Our smaller chainrings paired with wide-range, 10t-start cassettes provide more efficiency and more time in the big ring. It's modern gearing for today's riders. - Crisp and accurate front shifts - Durable finish - X-Range gearing technology gives you more range and a smoother gear progression, so you're always in the right gear

Original equipment on SRAM and Truvativ cranks, they also work well with other drive trains. - 7000 series aluminum provides strength and durability

- X-Range gearing technology gives you more range and a smoother gear progression, so you're always in the right gear - New tooth profiles for improved wear - More durable finish - 94mm BCD

- X-Range gearing technology gives you more range and a smoother gear progression, so you're always in the right gear - Specially designed tooth profiles for improved wear - More durable finish - Bolt Circle Diameter (BCD): 107 BCD - Speeds: 12 - Material: Aluminum

Intense study of chain and chainring wear patterns led to the radical tooth profile that lasts longer, runs quieter and further improves chain retention. Oval ring shape for riders that want to adjust the power profile of their pedal stroke. - The only oval rings with X-Sync 2 tooth design - Direct Mount Type: Direct Mount SRAM - Drivetrain Speeds: 10, 11, 12 - Material: Aluminum - Ring Position/Type: Chain Retaining Single Ring - Round or Oval: Oval - Chainline/Hub Compatibility: 141/148 Boost Hubs

- X-SYNC 2 chainring design increases chain retention, wear life, and reduces friction and noise. - Designed to be used with Eagle chain
