Out on my Bacchetta yesterday I suffered from severe cramping in both calves, even to the point of having to stop and stand to stretch them out. I found toes down or toes up both seemed to make it worse while clipped in, and it was worse on the flat or trying to hammer down hill. I tried sliding down and up the seat in case my leg length was wrong to see if that might help, all no no avail.
Any ideas why I might have suffered, I must be set up wrong somehow.
