Given that it’s pretty hard to walk into most bike shops and try out a HongFu bike frame (ignoring the many bike shops selling them as their own brand for the moment) it seemed useful to try and help out with sizing the frames as much as possible.
One recent innovation in sizing frames has been using Stack and Reach measurements because these can easily be compared across frames and sizes.
Most geometry charts still don’t come with Stack and Reach measurements yet, so I’ve created a calculator, preloaded with the FM015 & FM028 geometry.
Try it out now and let me know what you think: Frame Size Calculator
