    32x18 or 34x18

    Hello all,
    I need opinions on gearing. Right now my bike is geared to a 32/18. I am considering a 34/18. Should I go increase my chainring to a 34t ?

    Thank you

    Yes, definitely! No, of course not! You need 32x17! Go 33x18!

    I kind of think that's your decision mate.

    If you can climb absolutely everything on your regular rides with the 32x18, and find yourself spinning out too much on the flats (if you have any), then try a higher gear. The worst that will happen is you'll go back to the lower gear. And then you sell a 34 tooth chainring on MTBR classifieds, Francis gets two clams, someone gets a chainring, bla bla bla.

    Agree

    I'm on the same boat, I usually find myself spinning on the flats but still haven't been able to handle the climbing aspect and that's why I'm sticking with 32x18 until I can handle 100% the climbing aspect.

    How about going 32x19?

    Imho

    I think if you want to go with a 34x18 then by all means, go ahead and change your 32 to a 34, otherwise you'd still be running a 32x18.

    Seriously though, it really is up to you. We could all tell you to run 34x18 but you may not like it. We don't know your terrain or your strength and riding ability. The only way is to try it. And like Mikey, you may like it!

    Yes change your ratio and try it.
    Live by your gear ratio chart

    32 33 34
    16 2.00 2.06 2.13
    17 1.88 1.94 2.00
    18 1.78 1.83 1.89
    19 1.68 1.74 1.79

    Be ready to change your ratio every ride.

    Be ready to add or remove chain links if needed.

    Dude, depends on terrain and your strength. How do we know what you should be riding?

    I did just that earlier this year. It took me about a week to put a 20 tooth freewheel on the back. I didn't have a 19 tooth laying around. So, while I started out at 32x18, I ended up at 34x20. I actually went backwards a slight amount, but I'm happy. Results may vary.

    Idea! Works for me..

    I've been running 34:18 ever since I to switched to a standard crank (ran a 32:16 before). Yeah I spin out a bit more (I think, no way to know for sure), but I seem to make most the hills (which I did before the switch also). Either I've gotten stronger or I can grind up steeper hills. Like the others say you need to find a gear that works for you most the time; 34:18 works for me.

    34/18 felt faster

    34/18 seems faster but in my case 32/18 is faster and less tiring in the long run.
    Depends if you're a masher or a spinner.

    I think it takes a while to really settle on a gear.
