Hi
It will be an expensive mistake if you get it wrong!… suggest you take other measurements for reach etc. then check with your supplier…
Am I correct in thinking that the Creo 2 is more adventure/gravel oriented? I don’t think it would look’ wrong for you, with your height, it’s just if you’re going to feel too stretched out. There are obviously adjustments that can be made to saddle fore/aft/height but I think pro’s usually go for the smallest frame they can get away with in order to save a bit of weight… finally I would compare your existing bike measurements specs with the new one on order… hope this helps but mainly, enjoy your new bike!
