Great thread!
I have no major confributions (yet, it's only a matter of time
), but I do have a helluva lot of tales regarding brake and gear cables. Like fitting cables that go to the wrong brake, or taping the bars then realising it's impossible to thread the inner through an STI lever. Then realising it's impossible to bolt up an STI lver when you've already taped up the clamp. Then realising it's impossible to remove cork bar tape without destroying it (foam tape is ok though. Took me how long to realise that such stuff existed?). Or fitting a higher stem, and then not being able to work out why my front brake housing is too short to reach the brake.
