Ruptured Patella tendons, currently 19 weeks after injury, 1 week after removal of circgage wires and I am ok off crutches for short walks. I was able to cycle on a turbo for ~ 1min x 3 per day prior to the wire removal, but too soon to give it another go. A lifetime of limited flexibility, neck and back injuries have plagued my cycling, but at 60yrs I am eager to keep and improve what fitness I have. Incidentally to keep me amused and to aid comfort, I have increased tyre width and fitted a shorter crankset. I know Vickster has a lot of experience in this area, so it will be interesting to hear his comments.
