Thanks for the tips. Yes, I do have a computer mounted on the left so I suppose it could be contributing. When I put the bike in the workstand I always tilt the bike nosedown a bit to prevent the front end swing.

I wondered about the headset but wasn't sure what to look or listen for. The website you provided helps a bunch. I will have to rely on the LBS though for repairs, if needed. I got a 5 second teach-in on headset maintenance when I got the bike, but do I remember?

I'll let you know if I learn any more!
