Shimano Ultegra CS-6600 10 Speed Cassette

$95.00

689228077188

The Shimano CS-6600 Wide 10-speed cassette is specifically designed to meet the demands of junior category racing cyclists that must adhere to gear restrictions during competition. These cassette ratios, with their larger-than-normal smallest cogs, are designed to be paired with standard-sized road double chainrings (typically a 53/39T combination) to meet the gear restrictions.
  • Special cassette ratios meant to adhere to junior gear restrictions in sanctioned road races
  • Note: 13-16T smallest cogs might interfere with chain stays or seat stays of specific frames
  • When mounting, make sure there's proper clearance before riding
  • 14-25, 15-25, and 16-27T cassettes are not designed for triple front drive systems, as shifting performance will drop
