The Moulton designed, but Pashley built TSR is a beautiful machine, and a gigantic improvement over the Pashley Moulton APB that the TSR replaces.
But one thing that some Moultoneers are not happy about is the rear rack situation. The APB had a large platform rack, which was supported by a strut that extended from the back of the rack to the bottom of the seat tube, near the bottom bracket. In fact most Moulton models since 1970 have had this arrangement.
However, soon after the TSR launched, it became clear that the design of the rear triangle seemed to preclude this arrangement. It seemed to take quite a long time for the racks to become available, too. When it did arrive, the TSR rack was supported from above by 2 struts which attach to the top of the seat tube.
People I have spoken to don't seem to like this as much as the old APB arrangment, but the concept is growing on me. The APB rack wasn't the most stable, and was prone to shimmy at high speeds. Next time you see one, grab the sides of the rack and see how much you can move them up and down. Having 2 supporting struts must surely improve this situation.
