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.

Balance is the key to optimum performance in a stage race. Experience the perfect blend of grip and comfort that teams AG2R La Mondiale Pro Cycling Team, Lotto Soudal and Movistar Team use to win in the pro peloton.

64BCD chainring for MTB cranksets

Shorter—Narrower—Lighter—Faster. The 612-R offers more performance based ergonomics from 150 g. The raised rear gives more grip and better power transmission. A big advantage on straight roads and especially uphill. The stronger narrower mid-section and the narrow saddle nose gives more legroom. The proven SQlab ERGOWAVE form relieves the soft tissue area and prevents energy-consuming bad posture. The saddle shell is weight and flex optimized down to the last detail. More longitudinal stiffness and perfectly coordinated material flex to the side mean more comfort with less weight at the same time. The cover is extremely light but also abrasion-resistant and non-slip. The padding is closed-cell and strongly minimized. The comfort comes from the shape and the flex behavior between rail, shell and foam, which is coordinated as an overall system.
