[MENTION=65684]cobba[/MENTION] - I'll add photos once the sun's up. I've only got the one light in the living room where the bike is.
[MENTION=135358]xenologer[/MENTION] - how would I go about bending it to fit? I'm in student housing so I don't have a garage or workshop. Seems like the most promising solution, if I could somehow get a setup and step-by-step on how to do it.
If it's not something I can do in my living room with only a household toolkit, should I head to my LBS and ask? (Might be worth it to have them realign the caliper after I've been messing with it).
