I'm looking at saddles for a LHT I want to put together in the spring. I love my b17 on my road bike but would like to explore sprung options. The question I have is, does all the bouncing around from a sprung saddle effect pedal form much? Seems like each bounce would move you out of the fit zone a little. I'm really sensitive to fit, just a few mm the wrong way and I hurt my knees easily. I also tend to spin high cadence these days. Should someone like me stick to a rigid saddle? Unfortunately, There are no places near me where I can test one out, if I want one it's going to have to be ordered.
