I got my p&t in June when I still had just dc1 and it was great then in Sep when dc2 came along the handlebar started to jam and the buttons wouldn't push in to adjust the height. The frame seems to look bent when its put up, one side seems higher than the other and there is a gap down one side with the doubles kit on. Neither me or DH can think of anything we may have done to it to cause the problem and a screw came out of the handlebar the other day! Has anybody got any experience is this/is it a known fault?
