  • I've ordered an 11-32 cassette.

    What size front ring should I go for?

    I'm thinking a 46, which should give 40mph at a 120rpm downhill spin and 6mph for a 50rpm uphill grind.

    Thoughts pls.

  • I'm in the process of giving 1x a crack too, and have settled on 48 x 11-32.
    It give more or less the same total GI spread as 53/39 with 12-25 cassette which I've currently got on one of my road bikes.
    But, YMMV and of course will be subject to your local terrain.
