Want to convert my current single M780 crank/narrow wide setup to a 2x10 so will be running 2 rings on a triple crank.
Will a 2x mech work or do I need a 3x front mech?
Thanks.
Either will work so far as I know...
If your using the middle and granny rings, I'm pretty sure the cage on a double mech wont be long enough.
I am doing that at the moment, triple XT front mech with an XT triple crankset but just twin rings, all fine. If you are using a triple shifter, still works fine but you need to make sure the outer limit screw is adjusted to suit .
Thanks!
Was hoping to use a double front mech as it's going on a 2014 spitfire, I've read they have clearance issues on the front mech.
In my head I would get more clearance with a double mech over a triple mech?
Will be using granny and middle ring.
currently running an xt double mech on an xt triple crank ( 26t granny and 38t middle ring, no big ring) - works well, much better than the triple mech on the same ring combo.
Im currently running.......
XT triple chainset as a double (22 x 34 x bash)
XT 2x front mech
Works perfect with no rubbing in any gear - but the cage is much shorter than a triple. I think if I were running 22 x 36 like I used to it might rub in certain gears. But this ratio is a bit pants IMO - too bigger jump to granny and occasionally loose the chain when shifting down.
Looks like it should be a goer then!
Will be running 24 x 36 so going off the above and providing frame clearance is good it should work (fingers crossed).
Cheers lads.
