Road cranks on mtb
« on: May 15, 2009, 11:07:53 AM »
I am trying to put a compact road crankset (octalink) on a G.F.  Big Sur as part of a cross retro rebuild.
Has anyone successfully overcome the Q -factor with this type of application?
Anyone have a shimano octalink v.1, BB M952, 116 mm? 
I don't know if this would work but I would like to give it a try.
It seems that I could get a longer bb by going isis or square taper, but all my boneyard cranksets are octalink compatable.
Thanks.

Front derailleur height. You'll have to move the clamp so that the FD will line up with the crank properly.

Check the spec sheet for your front derailleur. They are limited to what they can shift as far as how big the big ring is and how much difference there is between ring teeth count. I'm dealing with this right now on my road bike. Had to order a new large ring so that it will work with my derailleur. Damn thing better work now  >:(
