I'm hoping to plunge into some commuting/touring this summer, and I thought this would be a good start. However, I'm having some trouble with the installation. The rack mounts using two aluminum mounting bracket arms. My bike also has threaded bosses for mounting. However, when mounting the bracket arms they are notably wider than the width of the two bosses on the seat stay. Also, more of a concern, is that the left arm aligns directly with rear break.
Outside of bending the heck out of the mounting arms, I'm not sure what to do. Is it possible I purchased an incompatible rack? I'm not sure how a different rack would mount any differently.
I know this is a shot in the dark, to even find you still active on this part of the internet, but...
did you ever figure out what to do about this problem? I just encountered it myself trying to mount a rack, and was wondering what you did about the interaction with the rear brake arm, as it is right in the way. I'd hate to have to replace the brakes just to put on a rack (i.e. wouldn't, probably)
