    Cross Gearing Question

    I'm planning on racing cross this season, and almost have my bike built up.

    I'm going to be running 46/38 rings.

    I have a 12-26 cassette and an 11-32 cassette.

    I was wondering if I'd lose anything by leaving the 11-32 cassette on there because I want to take the bike on mtb rides every now and then. Or should I just switch cassettes for an MTB ride. I have a feeling that I'll need to, right?

    Will the 11-32 make me lose out on anything in a cross race?

    I was thinking of putting the 12-26 on a different rear wheel for when I feel like riding the bike on the road in crummy weather. So then I'd put a wheel with a 12-26 in there and swap the 46 for a 50 ring.

    I wouldn't use the 11-32 for cross. I think the larger jumps between the cogs will make life hard on you during the race.

    12-26 would be my vote. If you think you need something more then that, you're better off running.

    A lot of people around here seem to disregard this, but I think it's a noticeable effect. I'm using a 13-25 cassette this year because I never hit the 12t cog and I like the idea of having an 19 between 18 and 20 -- two 5.5% jumps in place of one 11%.

    Maybe it's overkill, but cross is all about efficiency.

    Ah got it.

    The 11-32 will be a must for the mtb trails though right?

    I'd say so. I'm running a 11-34 on another wheelset for mountain bike / rail trails.

    that's up to you and your trails. i will occasionally ride my cross bike on trails with my 48/38:12-27. the 38:27 is somewhat easier than my ss 29er ratio of 32:21, so i don't mind too much.

    Up to you. I used my 30:34 a lot on mtb trails, yes. I now have 26:34 and will probably use that too
