I had a really cheap saddle on my bike for security reasons but as its a sit up and beg roadster and my lower back has had issues in the past its not good. Im upgrading to something costing £25 with elastomer springs. Im a bit worried about it getting pinched. I can't use the ball bearing track as the seat post is nut and bolt, not hex bolt, due to being an old bike. How about painting my name on it? But will the paint rub off on my rear? Any other ideas?
