I switched from SPD to Speedplays this winter. On the trainer, I have no problems clicking in/out. However, on my first ride today, I was tooling along just fine and then about 1/4 in to my ride, the foot I always clip out of at stops would just NOT click back in! I tried with all my pressure, different angles, looking for debris... argh!!!! Could I have done something to the combo, at some point during the ride???? Any help would be great...
