As far as I know it is. I have it set fore and aft so that the front of my knee is directly over the spindle when the the pedals are at 3 and 9. The height is set so that my leg is fully extended when the heel of my foot is on the pedal leaving a slight bend in my leg on the down stroke when the ball of my foot is on the pedal. Angle is set at what I found to be most comfortable. This has helped with knee pain, but it still gets me on longer rides. I would really like to get the frame sizing resolved so I can get on with ordering a LHT to fit up.
