I got the light action speedplays...and when we first put them on, I could not get them to easily clip in.....wasn't sure what we were doing wrong..... Then we added a couple of the shims that came w/the cleats...and then BINGO..they went right in!! (& I have carbon soled shoes...which they said would NOT need shims!!)

I'm still having issues clipping IN quickly on rides...but it could just be ME, they are supposed to be "light action"...and while they are a HUNDRED times easier for me than the spd's were.....I'm still having issues getting used to them!!
