Speedplay X2 here. There are pros and cons.
pros.
easy to get in and out of.
excellent if you have dodgy joints. I have problems with left knee and ankle from an old injury. No problems since switching over.
They look the mutts nuts. 8)
cons.
How much ???
Replacement cleats, how much ???
Bit of a pain to set up (but, once you have you won’t need to fiddle)
PITA to walk in. You will need cleat covers, or spare shoes.
You will need to do regular maintenance to keep them running smoothly, which means buying a speedplay grease gun and grease, which again means, how much ???
