The bike is still in progress as far as the build is concerned. I have been distracted by randonnees
The strut length was crucial to getting both BB height and chainline. On the test rides, things seem to have worked out quite well from both points of view. The triple is quite important to me, simply because of the terrain where I live; it's hilly.
I still have a few things left to do such as brazing a trailer hitch point on to a chainstay, and fitting a decent front derailleur. After that, it will all be stripped down and painted... a winter-time project here.
