Leg extension is where it should be, that one is pretty easy. The saddle and bar elevation and length are more difficult for me to check. I've adjusted my saddle so my leg is close to 90 degs when the petal is parallel to the ground. I don't know how to tell what's right with the bar adjustments. I suppose I could go have it fitted, but that's 50 bucks I could spend on more bike gear
It doesn't match up too well with the Roubaix, the geometry is different.
