I am relatively a (older) beginner to cycling and I have been trying to use clipless pedals for a coupleof days. However, I have not managed to clip in with my second foot once. No matter what I try it seems I cannot clip in. The tension on the LOOK Keo pedals is set at the lowest. I had a couple of falls in the park and my ego and fancy bike shifters are now all scuffed up. From what I read online this seems normal and it is something you get by trial and error. Any tips or help ?
