I've been playing with my bike set-up of late, mostly trying to get the right saddle height. I now seem to have it all dialled in and it feels pretty much spot on - I rode the same 50km course I've done about 100 times previously and managed to up my average speed by about 0.8km/h (which to me was a massive improvement).
But, something is still nagging away at me:
When I look at the pros riding what seem to be ridiculously small frames with massive setbacks and 140mm stems...it seems to fly in the face of KOPS... I.e. with such massive saddle let-back surely their knees are way behind the pedal spindle?
So how valid is KOPS?
