Currently they have the black plastic clip-on platform that came in the packaging. If they are fine for dry conditions, without black plastic thing, then I might use them as that would be the only time I would. Right now I can sell them for the best price as they haven't been installed and are still sealed in the packet.
On a different track, how does the cleat and engaging system differ from SPD? I have used SPD before really didnt care for it much. The Crank Brothers system easier to disengage? Being a newbie to MTB's, I would like something that comes out easy enough in case I have to bail! I'll check out the acid and mallet too.
Thanks.
