SRAM reengineered 48/35 tooth road gearing: reducing front chainring size and adding more range to the rear cassette. We also maintained a 13-tooth delta on all chainring pairs, ensuring precise shifting for any setup. This results in more useful gearing and better shifting across all configurations. Improved front shifting performance for crisp and accurate front shifts. Unique chainring shape results in a lighter weight, stiffer, more durable crankset. DUB bottom bracket adds durability, simplicity and broad compatibility.
