I noticed on a trip last weekend that if I let go of the handlebars at about 60mph, while the bike slowed down, the handlebars started wobbling quite a bit. It got stronger at about 50mph. I can't really feel the wobble while I'm holding on to the handlebars, but when I let go it is a fairly quick wobble moving the ends of the handlebars forward and back maybe 3/4 inch.
I understand from other threads that this is probably a front tire problem (?). Is it a bad tire or a bad balance job, or could it be either one? Is it something I should have looked at, or should I just ignore it?
Thanks. -bg
