Just wanted to share my experience of hitting a nasty pothole which ended up bending the rim of the back (drive) wheel. The tire lost air immediately due to the deformed rim so I was reduced to pushing the bike through the streets of Cambridge, MA in search of some help. Interestingly, none of the mechanics that I stopped at (including a tire place) were game to help me out. I guess they were worried about cracking the rim if they tried to bend it back. I ended up at a motorcycle place, where I thought I would finally get some relief from wheeling the thing around in the 90 degree heat. No joy. They couldn't/wouldn't help me either. So I asked for them to lend me a hammer so I could try fixing it myself. What else was I to do? Anyway, the good news is that through gentle and persistent hammering, I was able to bend the rim back into alignment enough for the tire to seal against it and hold air. See photo of the end result...
Not pretty but at least functional!
I was wondering if anyone else has had similar experiences and also if anyone has replaced the back wheel. I haven't asked John and company about it yet - maybe they might have a spare rim rolling around. Not sure how big a deal it is to swap it out.
