wrote: Actually, I mentioned Rivnuts when I posted the very first reply to Emanuel's original post. That was about eight hours before the post you quoted. Sorry, I missed that. Also note that he indicates that "the chainguard is mounted on the stays...". Which of the stays, he doesn't mention, but it doesn't matter. Chain stays and seat stays are both rather small diameter. The reason I'd like photos is that Emanuel seems to imply that a hole in the stays is the original method of mounting the chainguard. I think that's unlikely. I wondered if there are brazed-on tabs or some other feature that we don't know about. Photos, from his web site: http://user.it.uu.se/~embe8573/work-photos/ This might be the bicycle. Notice the chain guard and welded mounting bracket in the middle of the right chain stay: http://user.it.uu.se/~embe8573/work-photos/hermes.jpg Mo http://user.it.uu.se/~embe8573/work-photos/stand.jpg ISTM that Emanuel isn't very clear on many bike-related terms in English, and he seems to be a novice mechanic in general. Some of his descriptions may be unintentionally misleading. Yep, probably because he thinks and writes like a programmer. In the middle of the main program, he services an interrupt and jumps to different topic. Since the there's no return pointer, he doesn't go back to the main program. He also tries to service all the interrupts and topic changes in parallel, when it would be better if they were handled serially. A general failure to define the parameters and variables used leave the user wondering what equipment he's working with. Without initial comments, it's also difficult to know what he's trying to accomplish. I think his postings would be less buggy if he masked all interrupts, executed only the main program, added enough comments to help debug the problem, and only then branch off into subroutines, which hopefully will eventually return control to the main program.
