I've gone for one, I'm 182cm and when comparing to my other bikes, I need to run a 90mm stem for the same reach on a size 54 (I normally run 110mm).
I've gone for a pretty out there dark grey glitter paintjob (hey, it's gravel) with some wheels from 'Peter' and an ltwoo e-gr groupset. Magene PM crankset with an alugear 1X (orange) chainring. Will post the full build when everything arrives.
