Well I dont know if I am getting old or what but after a muddy 4 days at hatfield mcoy I needed new pads on both ends. I took the forks off and did the steering bearings and then put them back on. The tire is still off with the bike on the stand while I wait for the parts to come in. Anyhow I noticed that one tube is about 1" lower (or higher) than the other. There set the same up top and I know when I put the tire back on I can push them back even but should they be like this? No seal leaks either.
