I ride a 80's Fuji road bike with an updated/modern wheelset.
When I lift the front wheel up and sort of bounce it off the ground it makes a rattling noise. I noticed however this doesn't happen when the brake is applied, which leads me to believe it is something in the rim rattling? My rear wheel does not rattle at all.
I've checked all the spokes and nipples and nothing seems loose. I've even checked the tube valve to no avail. Is this just the front fork vibrating and is completely normal?
I've had his wheelset for a year now and I only noticed this a week ago, although It could've been happening for longer without me really noticing until now.
