I have had a tough two days. Yesterday, my track hub went and cleaned all of the threads off of the part for the lockring. Today, after work, I noticed a certain flatness to my tire. Went to the shop, got a new tube, and not even an hour after intsalling it, BOOM, second flat of the day. Whats next?

Edit: And yes, I did clean any foreign object from the tire. Flak Jacket technology my ass.
