Is there a Velosteel order still open? I am a newbie lurker, but I have been rebuilding all brands of coaster brakes and building road (coastie?) wheels for a few years.
Alaskan winters can cause bad problems for brake and derailleur cables, so my builds have been a popular solution with my bike wierdo friends. Most of the frames I have used are old road bikes with horizontal dropouts, so I usually end up putting lots of washers on the axles.
The clutching mechanisms are the issue in most of the hubs I have rebuilt, and I have put new projects on hold until I can get something more durable.
