After my recent trip to Northstar my bike (pics here if needed) developed a vibration that's very noticeable even when just rolling it on smooth pavement. It seems to be mostly vibrating up and down towards the front of the bike. The vibration is low frequency.
I think it might be the headset. I've messed with it and found the spacers (this type) to be wobbly, but I don't know if that's the only problem. It has sealed bearings and a 1.5 to 1 1/8 (I think) adapter. How do I troubleshoot the problem?
