I'm thinking on buying a mtb perhaps a Trek X-Caliber which is fitted with a 38x22 front chainring so would it be OK if I went to perhaps 42x28
I would need a longer chain but would that be OK to do?

Cheers

    Just make sure you buy chain rings that are compatible with 2 or 3x front gear setups so you have the shift ramps on them for the chain to move up/down.

    A lot of chain rings these days are made for 1x gear setups and wont work on double or triple gear setups.

    Thanks sword 1..
    Just got myself a Trek Superfly 5 in the end and not the X- Caliber as the Superfly was just silly money and too hard to say no at the price.. But it still has the 38/22 so I will still change them?

    Its got a lot to do with it...

    Over here most of the mountain bikers race..they do all rough terrain riding over gravel, rocks, and boulders with 30% plus steep bits on 5 to 7 klm climbs.
    When I get the bike back to the UK I will be very tame doing bridle ways and foot paths plus roads too rough for a road bike? a bit tame I know.

    If it's just for casual riding it's a costly change to a brand new bike and probably won't make a blind bit of difference..

    I dont even know what number of teeth are on my chain ring! I'll only care about it when it wares out and I need a new one :oops:

    I wouldnt bother changing the rings.

    I will just try it out first for sure but I wanted to know if I could change the front chain ring because once I've rode the bike I can't take it back to the shop and I would be well hacked off if I wanted to change it and I couldn't.. :)
