I have knee osteoarthritis and have always been concerned about the front of my knee being over the spindle/axle of the pedal when the pedal is 90 degrees to the ground. This allows me to ride pain free. I don't stand too much so much of my pedaling is in the seated position when on level or climbing. Does anyone have the same problem and experience with the new geometry where the front end is stretched out and the seattube is more upright which brings one's knee farther forward? Lot's of new bikes out there which entice but fear of having more knee problems keeps me on my 2015 Pivot M429.
