cycling along I found that going at a certain speed the front brake disc vibrates loud enough to make a very annoying rattling sound. Below and above this particular speed there's no buzzing - is this a natural frequency thing? Unfortunately, it appears that it's also my current cruising speed I also found that the situation gets worse momentarily when I lean for a sharp turn. I have tried centering the brakes to no avail.
The rattling problem only appeared after I fitted a new and heavier tyre - Maxxis Swampthing 2.1. The previous was a Panaracer Tserv.
I do notice that when I turn the handlebars that there appears to be a slight delay of the rim/tyre to turn. Almost feels as if the hub to rim connection is slightly loose i.e. the spokes aren't tight enough. I have checked the wheel and tightened the spokes as much as possible but it still no good. So do I need to cut some more thread on the spokes of the disc side (left) so I can tighten even more? If so, who makes a thread cutter?
Incidentally the wheel is my first attempt at wheel building and so that may explain why everything isn't as it should. The rim is a Mavic 219 disc and hub is a XT disc. Incase it's a flexy fork, which I doubt, the wheel's attached to a Marz. MX Pro ETA. Thanks for any help.
