Hi there, I have just fitted my New set of speedplay zero's , I have changed from shimano spd L s, I followed the fitting instructions carefully but I am a little concerned at the ease at clipping out. With the shimano it was a "clunk" clipping in and a "clunck " at clipping out so you knew you were clipped in securly. However the speedplays are not so "cluncky" so I am a little dubious as to the securite of my feet in the pedal, I felt that if I sprinted I would pull out. As said I made sure that I did not overtighten the four cleat screws so that cannot be the prob, if there is one at all. Has anyone else experianced this? Is it just how speedplays are? nathan
