Chainrings

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.

Wolf Tooth designed these bolts to be the best on the market. They have a 4mm hex socket and are 10mm long so you can use a bash ring with your chainring that has threaded standoffs like the Wolf Tooth 104 BCD 30t ring, Elliptical 104 BCD rings, 76 BCD rings and others. No nuts are included with these bolts as they are intended for use with threaded chainrings. These work great with Wolf Tooth or any other brand threaded M8 x 0.75 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.

Eagle Technology creates the smoothest, quietest, longest lasting and most efficient drivetrains SRAM has ever made. The radical new look and feel of the 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 Eagle chains to increase chain retention and overall pedaling efficiency, while decreasing friction, noise, and wear. The complete Eagle system—crankset, chainring, chain, shifter, derailleur and cassette—is designed, tested, and proven to deliver the ultimate mountain bike drivetrain. Put simply, Eagle is capable of revolutionizing the ride for all riders on every kind of terrain. - Designed to be used with Eagle chains - Material: Aluminum
