    13-25 cassette?

    I've found myself in the 11 and 12 so rarely in races that I'm considering going to a 13-25. No, I'm definitely not a junior.
    Has anyone used this setup in road races and how did you find it performed?

    I've never used it in a race - mostly on the principle that if I need something like a 25/26/27t, then I want an 11/12 for the descents.

    I'd say get one,
    give it a try,
    if it works for you, then great, problem solved.

    Sure. When I raced in the mid to late 80s I used a 13-24. That and 13-21 or 13-23 were the common cassettes. 52/42, 52/39 and 53/39 were the chainrings commonly in use. 12t cogs were for fast p/1/2s and poseurs who wanted to look like them.

    i use 13-26 always, probably switching to 13-29 for 2012 which is what I raced a few years back also.

    i just did this - 50x13 @ 120rpm is 36mph (seems low to me, i thought more like 38?).

    i have no worries about getting dropped on the downhill of any hilly races. the more difficult is a race with a long, not that steep hill but you just have to either tuck or get on someones wheel or maybe burst a little.

    Absolutely go to the 13-25
    If you never use a 12, or an 11, why waste them?
    Now you can have a tighter block.
    And that just makes more sense.

    can only think of one race where i really needed an 11/12, and that was the pepsi stage at killington.

    Strange how everyone seems to "need" the bigger gears, when only a generation ago, the pros were still using 52x13.

    And yes, I know of the Pepsi stage. But that is one-off stuff of course. What speeds did the winners hit? 80kph?
