This is my BMCs geo, 100mm stem with about 25mm of spacers underneath
This is my Giants geo, 54.5tt with a 100mm stem and 6mm spacer underneath (bigger headtube)
This is the geo im tossing up between for the frame im currently eyeing, as you can see its its a 54 or 56
Ive had an older cannondale in a 54 with a 110mm stem and then the last cannondale which was a 56 with a 90mm stem, was much more comfy with the latter
Im leaning towards the L as the headtube is a little taller and i think a 90mm stem is fine from previous experience.
Any issues you guys see with my logic? or anything else im not thinking about? The frame is a CX frame if that makes a difference, but it will mainly be used as a commuter.
Im still nutting out details so nothing confirmed, but would appreciate some feedback
damn B! didnt think the geo was that obvious! Cats out the bag now! Its actually a 2016 Zydeco, found a mob selling as frame/fork from the states and hes quoted me $100 US to post
haha Heavy, wasnt really looking to flip but one of my work colleagues mentioned hed be keen, then i stumbled across a pic of the zydeco, and here we are.
you can’t compare headtube between a road and cross bike. longer fork for tyre clearancezzz means less headtube. (add ~20mm to your headtube in this case which will make it very nearly your bmc.)
Conventional wisdom is go the smaller size and component up to suit. I have several times gone the other way, having generally felt more at ease on a larger frame (especially in the TT). Went the conventional route for last roadie built and am now a convert.
