Description
SRAM Red XG-1290 E1 Rainbow 12 Speed Cassette SRAM's lightest, most durable cassette breaks new ground for gearing choices with four distinct cassette options, including their first 10-30T and 10-36T RED cassettes, each provide secure shift ramps specifically designed for electronic shifting, whether racing road on a 10-28T or creating an all-road setup with a 10-36T. Carefully chosen tooth jumps keep the rider in the right gear when out of the saddle on steep climbs and making fine changes to hold a wheel while approaching a sprint.
