I have read many discussions of Q factor, but I remain confused. I ride about four bikes with some frequency, all with significantly different Q factor. I don't seem to have any problems with knee pain or anything else. Also, these cranks vary in length from 170mm to 181mm (Cook Bros).
Here's my question: I want to put a road double crank (currently on my Merlin road bike) on my Ritchey mountain bike (currently has Cook Bros triple), because I want to use the bike as a road commuter and don't need the triple. The road double is a Ritchey Cross with 34/50 rings. I am planning on putting the Ritchey crank right on the Phil BB currently on the Ritchey bike, so the inner ring will clear the chainstay.
Can I anticipate chainline problems, or does anyone see any obvious problem with my plan.

chain line is likely less of an issue than the cranks striking the rear stays. most mtb's, are much wider than road bikes in this area to accommodate larger tires, with those made of aluminum being the widest of all. if it fits, great, but don't be surprised if it doesn't.
