A month or two back I managed to do a dumb 1mph crash in my back yard that ended up bending my front rim. I sourced replacement rims (Alex DM18), and rebuilt my front wheel. Everything went pretty well until I did a quick test ride the other day to see how things were settling in, and discovered that my bike now wants to pull fairly hard to the left.

I've spent several days now trying to see where the problem might be - my suspicion is that I tweaked the fork a bit in the crash, causing the wheel to be canted ever so slightly. However, I can't see anything obvious and when I try checking alignment with a straight edge I can't find any significant issues.

Question: how do I determine where the problem might lie? If it is the fork, is it possible to twist it back? If not the fork, what do I look for in my wheel building that might be causing this issue?

Bike is my Peugeot AO-8 - stock frame and fork....

Any advice is much appreciated....
