I am trying to change from 1x9 to 2x9 by using a triple front mech. I don't seem to have space between the rear tyre and the mech. Can anyone help - it is an LX triple bottom pull.
Thanks
Is the lower limit screw set right ? Also, the outer cage should clear the outer ring only by a few mm IIRC.
I haven't managed to set the screw yet as I cannot get it to fit onto the seatpost. I have a dual pull mech and it is worse!
I'm hoping you mean seat tube, i ran my swift 3x9 with a deore mech didn't have clearance issues
A pic might help.
Set the limit screw right in before you install it then back it off. Clearance is tight on most 29ers but sometimes you can solve it with a different mech.
What size tyre do you have in the back? I found a 2.25 ardent about as big as I could run with a triple mech
I'm on 2x10 on my swift ans have done 2x9. both work fine but I did find that I had to set the ebb at its highest position to get the (double specific) front mech to clear the chainstay with a 32t chainring. no tyre clearance issues but I'm on 2.1s.
I am running a 2.4 Ardent and I wondered if that was the problem as it sits quite high on the rim. Rocketdog - I wondered why the chain wouldn't stretch!
CX-70 cyclocross mech is a bit lower profile but I don't know if it will be compatible with your choice of shifter.
2.4 ardent will definitely foul the front mech, too big if you're running gears on a swift ime
Hmm, no suggestions ... but if it helps I'm running a 2.4 Conti Mountain King (v1) with an XT M781 on my Swift (3 * 10 setup), and the clearance is good.
Actually, "bottom pull" ... but is it a top swing mech, or a bottom swing (a low-clamp or a high clamp?). It shouldn't really make much difference, but I've found that I've had less clearance with a top swing/low clamp than with a 'conventional' bottom-swing/high clamp mech. YMMV I guess?
If all else fails I've found the vanilla Deore f-mech (M5[i]nn[/i]) fits/works with [i]almost[/i] anything, equally happy pulling both ways, loads of adjustment range and just seems to keep going for ever...
