huh, this equation sound interesting. mostly because I have never heard of it I suppose you measure from fingertips to fingertips?Davico wrote: ↑Wed Dec 05, 2018 5:08 amWhat is your ape index (i.e. body height minus arm span)? If the resulting figure is positive, go with the smaller frame; if it’s negative, go with the larger frame. I ride an SLR01 in size 58 (recommended for 184 - 192cm body height) and it’s a tad small; my height is 189cm and my arm span 195cm. I use a 140mm stem and have the seatpost 23cm out to compensate (my legs are also rather long). It works but I would go with a larger frame with what I know now.
I still have to measure exactly...but I think in my case I am somewhat even (around 0). So bad indication.
I thought on jumping on the 51 since it seems really to be a good deal. Not even done it and already thinking of a wheel upgrade
