Well the train heap has finally died so it's out with the folder again (also very useful after the massive influx of ex tube/bus passengers to the trains post 7/7). Only problem is the seat tube is too short, and makes pedalling just that little bit excrutiating. Being a long folding bike steel type with the usual tapered clamp on fixing it's not just a case of buying a longer one. Is it possible to get extension tubes? the diameter is 29.2mm.
