Spare parts

What type of CLEAT can I use with power pedals?

I want to change bodies. I have a pair of X-TRACK POWER can I install a KEO BLADE POWER body? I have a pair of KEO BLADE POWER can I install an X-TRACK POWER body?

Can I install the blades of the KEO BLADE on my KEO BLADE POWER?

Is the body of a KEO BLADE compatible with an KEO BLADE POWER spindle? Is the body of a X-TRACK compatible with a X-TRACK POWER?
