I have a custom steel cross bike that has one eyelet for a fender on the drive side, but no eyelets on the non-drive side. The bike has disc brakes so I have access to the two bolts that hold the rear disc brake. Can anyone think of any issues with putting the fender stay between the bolt and the disc brake tab, kind of acting like a washer. The disc brake bolts are cranked down tight so I don't think it would loosen up, but I'd like to hear what others say. Thanks.
