divernick Posted May 25, 2012 Share Same applies as per the 3 ring crank where you might need the spacers or shortened boltsAlso depends on whether or not you want to get a new chainring at some point. Most (not all) MTB chainrings have a BCD (bolt centre diameter) of 104mm. I know that some 2x10 cranks differ from that. Link to comment Share on other sites More sharing options...
RossW Posted May 25, 2012 Share Same applies as per the 3 ring crank where you might need the spacers or shortened bolts So....I can use the outer ring, put on a suitable tooth ring and then just line it up with the rear cog?Sounds excellent then!

Hairy Posted May 25, 2012 Share So....I can use the outer ring, put on a suitable tooth ring and then just line it up with the rear cog?Sounds excellent then! In principle yes. In practice, tell us after the weekend! I am pretty sure though that it would work. Link to comment Share on other sites More sharing options...

I know that some 2x10 cranks differ from that.Yes, the 2x10 have a different BCD ..... I think it limits my options extensively. Research shows the BCD is 120mm on the outer (big) ring Edited May 25, 2012 by Ross Winckworth Link to comment Share on other sites More sharing options...

Don't forget the chain tensioner and spacers Edited May 25, 2012 by Hairy RossW 1 Link to comment Share on other sites More sharing options...
divernick Posted May 25, 2012 Share On a 2x crank, pick the inner or outer chainring position that will give the best chainline. Anything between 31 and 39 tooth chainrings will work, depending on your rear cog selection. Most guys on a 26'er run 32x16 and on a 29'er run a 32x20. I run a 38 x 20 on my 26'er Link to comment Share on other sites More sharing options...
RossW Posted May 25, 2012 Share I know it's a case of each to their own but do you think it's a feasible idea to stick with the 39t in front and use a higher toothed cog in the rear, like a 22 etc. Depending on the tooth options available? Don't really want to have to shell some Rand on a new chain ring when I could make do with what I have already. Link to comment Share on other sites More sharing options...
divernick Posted May 25, 2012 Share The higher the tooth count, the more chain-wrap you have and less chance of dropping the chain - even if it's at a slight weight penalty Use what u got and save for what you want..... RossW 1 Link to comment Share on other sites More sharing options...
