I've bought two French built rando/touring bikes and they both had internal wiring from a hole at the back of the bottom bracket to a small hole just beneath the bottom head lug.
The wire was then run through the underside of the fender to the taillight and the front rack mounted headlight, held by small dabs of epoxy. Although the dynamo was mounted on the chainstays (a Sanyo tire dynamo), this routing would work for a front hub dynamo also, although you'd also need a small entrance and exit hold on the fork as well. The hole required is no larger than a typical brazing vent hole so I wouldn't be concerned about strength, but I would have a pro or very experienced bike mechanic do it. - Taz Taz Taylor Atlanta, GA <https://lh3.googleusercontent.com/-rkmSwg6kTD8/WYOiPcJw9bI/AAAAAAAAAz4/rfGUDFduGLEI9N0k2fNTGj6iBWqt4NJAQCLcBGAs/s1600/IMG_1223.JPG> <https://lh3.googleusercontent.com/-nPEtHqhZNZY/WYOidkRCX_I/AAAAAAAAAz8/bDfblBQk7fEJ-3clWK9VpWd5O5MofZfwACLcBGAs/s1600/IMG_1245.JPG> <https://lh3.googleusercontent.com/-Oagc95TPNmw/WYOisV_fkPI/AAAAAAAAA0A/8dWJfFt7GAEIsQOdKwQ0IaFjlMk2QWL5ACLcBGAs/s1600/s-l1600-11.jpg> > > -- You received this message because you are subscribed to the Google Groups "RBW Owners Bunch" group.
