I’ve been using SPD’s for years but just recently I’ve been experiencing on and off discomfort in my knees. I don’t know whether it’s my age and years of abuse mixed with the hours that I spend clipped in every day but I’ve decided to try something new. I have heard alot of good things about TIME atac pedals, especially on the subject of knee friendliness so thought I’d give them a try. It will probably take a little while to get used to the extra float but am hoping that my tired, old knees will thank me for it?!
