Surly’s Stainless Steel Chainring for 104mm BCD cranks is built to take abuse and keep spinning. Made from tough stainless steel, it’s far more wear-resistant than aluminum and ideal for riders who demand lasting drivetrain performance. Compatible with up to 9-speed drivetrains and standard-width chains, this ring is great for mountain biking, touring, or commuting. Offered in 32–36T sizes, it’s a versatile upgrade for strength and reliability.
