Well Mr Wow, there you have me. I have never had this problem before. Hence my seeking advice.
In the past I have accidentally put my boxers on back to front and then had to stand at the urinal for some minutes trying to find my willy.
However, I have never had customer facing boxer issues before.
I suppose given my location I could pop round to SJS Cycles and see if they do Rohloff boxers but then I might suffer a cracked flange.
What to do eh?
