hate to say it, but my custom titanium bike with kinesis aluminum fork has always done that and after trying a bunch of stuff to fix it, and failed, i just learned to live with it. sometimes, i even manage to forget about it, but then something comes up to remind me again.

seriously, if it's no worse than mine, it's possible to learn to live with it. of course, you could always try another type of fork... good luck.

i just took the trouble to look at the bike at the giant website, and , IMO, at that price point a bike with a rigid front fork would be more likely to have fewer problems.
