How tall are you? I am curious how the 49cm fits.
Five ten and a 1/2; you can see from the last set of pics how the saddle is set up. The bike fits great. It's a 19.29 inch frame and I ride a 56-57 cm road frame (in a vintage bike). I could ride the next MB 1 size up as well which is a 52 but I don't think I'd like the top tube length as much. The top tube on the 49 cm is just about perfect for me at 23 inches or 585 mm.
The top tube, I think, is more important than the seat tube in setting up a bike properly.
