I am 3 months in from a total knee replacement so still early doors but at this juncture I have been on the Shadow to test what I can cope with. I can reach the handle bar and operate all the controls but the knee flection is currently too restricted to remain comfortable on the seat so to reduce the flection I need to drop the foot rest. To this end I have loosened the fixing bolt expecting the foot rest arm to drop through gravity and it doesn't. The back plate is keyed so I cannot move that up or down - so the question is how do I move the foot rest down? I am thinking of tapping the foot rest arm with a soft mallet but if it is splined onto the shaft I will only cause damage so before I do anything I need advice from someone in the know. Thanks.
