I've decided to experiment with my position on the bike. When riding I get a few little niggles which I think is down to too much weight on my hands and they are spoiling my enjoyment. I've put up with them but have decided enough is enough. My saddle is a B17 which doesn't have much fore and aft adjustment (a common issue apparently) and was wondering which seatpost to try and how much layback do I need. Anyone any personal knowledge? I'd like a titanium one.
