Well I don't know what's going on with/inside my rim, but it held up fine this morning when I made the sprint to Union. Queen/Ronces -> Union in 11 minutes 30. I may've been a sweaty pile of mess, but I made my train (just.. it was rolling in as I was coming down Simcoe to Front).
Thanks go out to Canadian Tire money for being the 'boot' material over the dodged tape area
