I have a brompoton with the telescopic pillar and a Brooks seat. When riding my body always gets to move slightly further back, but moving the seat as further back as possible was not enough. I also realised I probably could do without the telescopic pillar, and use an extended one (I am 1.88m). I have read about rotating the extended pillar to gain a bit of distance between seat and handlebars.
How much can I hope to get this way? Any other way of making my ride a bit more comfortable?
