It's hard to tell from the pics I saw (dial up, duh); but do the annodized pieces bolt on the shifter shaft - and then the shift handle bolts on the threaded shaft of the annodized piece?
If so, it looks like there's only a set screw to keep the annodized piece from rotating on the shifter shaft. On the one hand, I'd think aggressive pounding of the gears could spin that right around. On the other hand, the design looks so robust that I can't believe they'd miss something like that. So I must be missing something. What keeps the annodized piece from rotating once it's bolted down?
