It's been a while since I posted anything. I am still looking for a biking solutions for Sylvia but I have narrowed it down to either a Hase Pino or a tad pole trike.

A couple years ago I read about a shifter that is part of the bottom bracket and is shifted by tapping the heel. I thought it was called a 'Scrumph' shifter but my google searches have not turned anything up on this. Is anyone familiar with this system?
