I am of similar mind- the worst feature of my B5 is the rear brake. There's very thin "zone of effectiveness": a little less and it doesn't work very well, and a little too much and it locks up on you.
Thanks again those with ideas about the braking. Sounds like it is fixable. I haven't quite been ready to take the plunge, because it would be the third new bike in less than 2 years, and at this point, I just want something Ic an ride - breaking them in all the time can get boring - but right on the edge. It's just a smidgeon tall still to take the plunge, I would like a bit better than the balls of my toes. Maybe the springs needed to be softened slighty. Or a solo seat that is slightly lower than the stock.
