A reader sent me frame geometry for the FM-012 time trial frame. I’m not sure how TT frames are measured, but the seat tube is 49cm on this size.

A reader sent in the geometry for the FM-021 time trial bike frame. I don’t think I’ve seen one of these built up yet, but it looks like a great frame for time trials or triathlons

A reader sent in the drawing for a 57cm FM006 frame (thanks!). If you have any other sizes, please send them in ([email protected])

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
Discuss this at the new Bike Sizing Forum.
The FM027 (aka TP-R813) Â is one of the newer frames available. I haven’t seen any built up yet, but judging from the curves in the seatstays it should be a pretty comfortable bike to ride.

Here is the Hong Fu FM028 carbon bike frame geometry chart for 50cm, 52 cm, 54 cm and 56 cm frames. (Thanks to some readers for the 50cm, 52cm and 54 cm drawings. Does anyone have any other sizes? [email protected])

I also found a sizing chart from an ebay listing that appears to be for the FM028:

Here are the geometry charts for the HongFu FM015 bike frames, in the 53 cm, 55 cm & 58 cm sizes. (Update: A reader sent in the non-integrated seatpost drawing and a sizing chart. Thanks! Update 2: And now we have a 51cm drawing.)
