I helped you install a tube in your flat (and formerly tubeless) rear tire, in the Fromme parking lot, on Thu Aug 11 around 5:30pm.
On the off chance that you (or someone you know) sees this… I was a little worried about losing the daylight so I slapped that tire back together in a hurry. About 20min after leaving the parking lot I realized:
1) I did not check the rotational direction of the tire before installing it. There is a 50% chance it is on backwards, you should check that.
