Shimano CS-6600 Wide 10-Speed Cassette
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. Note that in modern-day frames with carbon fiber tubing, using a cassette with the smallest cog size of 13 through 16 teeth may not be compatible with the chain stays and/or seat stays. Also, due to compromises in shifting performance, Shimano recommends that these cassettes only be utilized with a double chainring crankset, not a triple crankset.
  • 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
  • Do not use those cassettes with WH-6600/WH-R600/WH-R601 wheels
  • 14-25, 15-25, and 16-27T cassettes are not designed for triple front drive systems, as shifting performance will drop

13-25 is PERFECT

    Comments about Shimano CS-6600 Wide 10-Speed Cassette:

    The 13-25 10 speed Shimano cassette offers the perfect range and single tooth steps from 13 to 19, where you need it most. With a 50 to 53 tooth big ring up front you'll have 100+ gear inches. Those 11 and 12 tooth cassettes sacrifice the 16 and 18 tooth cogs out back that give the tight spacing this cassette has. Sadly this one is getting harder to find and expensive when I do find them. I'm glad I grabbed a couple here while they were still in stock.

            Comments about Shimano CS-6600 Wide 10-Speed Cassette:

            I bought the 14-25 for the flats and somewhat hilly roads when I lived in middle Georgia, but now that I live in Florida with only the occasional bridge to cross, my next one will be the 15-25. It's great for the flats for old guys like me who don't race but want something close to a 10-cog straight block. Do heed the warning though for use with a triple crank; it has a delicate adjustment in cooler weather, and with just a 5-degree change in temperature , you'll find that you'll be adjusting the rear shifter cable tension more than you'd like ( I do it on the fly), but all-in-all it's worth it if you don't need increased range for racing.

            Thing is big. Careful the 16 barely clears my seat stay. Love the smooth shifting and low gears for the hills where I live. It is big. If you spend your time in the mountains climbing and you aren't concerned about going super fast on the flats....
