Bike fit / correct riding position

No; due to short hamstring and lack of flexibility, my right knee would push out sideways at the top of the stoke where thigh is closest to chest. Raising the bars meant shoulders higher so wider angle maintained between thigh and chest.

I was pedalling on a jig and the guy was shining a laser light down the centre of my knees so we could see when the motion was pure up and down rather than also going side to side.
