I currently have eggbeaters on my mountain bike. I started running a month or two after using the pedals now i have a pain in my knee. I took off the pedals (2 weeks ago) and have started running again and i have no pain in my knee. So i am guessing i need a pedal with more float. The eggbeaters have 6 degrees of float. I was looking at the ATAC pedal which has 10 degrees and the speedplay has like 20-26 degrees. I really like the ATAC pedal, but the speed play has more float, but speed play also has a lot of bad reveiws. Do you guys think the extra 4 degrees is enough or should i go with the speedplays?
