Surly Chainring

Stainless steel is significantly harder and more wear-resistant than aluminum. While it adds a bit of weight, it will last much longer, making it an excellent choice for high-mileage commuters or riders who prefer low-maintenance components.

No, this chainring is designed specifically for 1x9 drivetrains and narrower setups like singlespeed or fixed gear. The teeth are optimized for wider chains and will not properly engage with the narrower chains used on modern 10-speed and above systems.

Because this chainring lacks the specific shift ramps and pins found on multi-speed rings, it is symmetrical. Once the teeth begin to show signs of wear on one side, you can simply flip the ring over to utilize the fresh, unworn side, effectively doubling its lifespan.

This chainring uses a 94mm Bolt Circle Diameter (BCD) and a 5-bolt mounting pattern. You must verify that your crankset matches this specific BCD and bolt count before purchasing, as it will not fit standard 104mm or 110mm BCD cranks.

It is designed for 1x9 drivetrains, but keep in mind that it lacks the shift ramps and pins found on dedicated multi-speed rings. While it will work for a 1x9 setup, shifting performance may not be as crisp or immediate as it would be with a ring specifically engineered for shifting.
