I tried the Power on my mountain bike but it was too firm. It was absolutely fine on the cross bike though which I took to mean it works better for an aggressive bent over position. The Phenom on the road bike goes unnoticed which I think is perfect. And the Henge sits on both my mountain bikes but I find it needs a little up tilt to feel right. I don’t like to feel like I’m sliding forward. So more experimentation is needed.  I’d like to see you do an article on mountain bike fit though. The aggressive XC fit is one extreme whereas the super upright freeride fit is the opposite end. Which works best?  I think we have all read that steeper seat tube angles are more efficient but I’ve never read why it is so. Somewhere there is an optimal angle between torso and thigh when pedaling. Bolt upright is not it. Folded over isn’t either. I was fitted to my road bike with the Specialized kit and for me, a 74 seat tube angle but a 25mm rear set post head just gave me the “correct” fit. 75 degree is too steep. So a Pole frame will be ridiculous for me?
