Crank "Q-factor": is less always better?
Hello, all.
The old loose-ball bottom bracket on my Centurion has developed some pitting in one of the cups and seems to be on its last legs. I'm thinking about replacing it with a Shimano UN-73 cartrige style. Cranks are fairly old 105.
Anyway, looking at the BB, I'm struck by how much gap there is between the crank (and chainrings) and the frame, and how long the current BB spindle is. So I'm thinking I'll get a shorter BB and reduce my "Q-factor" a bit.
Is there any possible way this could be a mistake?
Thanks.
