What do you see as the big differences between frame sizes when you could ride either a size bigger or a size smaller?
I bought a large (still waiting to be built) with both the flat and drop base bars, 65mm stem, TSP & angled kits and the J and L bend extensions, but realise I could also ride the medium.
pad stack = 620mmpad reach = 509mm knees just behind elbows (but I’ve ridden the last few years at 530-535 or so).saddle height = 809mmsaddle set back (nose behind bb) = 15mm
