I'm afraid the levers got nabbed on PM a couple of hours before your post, sorry!
Yes, the Ritchey pedals are compatible with Shimano cleats - SM51 according to the instructions, but I'm pretty sure any of the SPD cleats work ok.
Pics of the wheels will come, I promise! Not really been in the house this weekend unfortunately.
To those who've bought stuff and paid, I had to work late on Friday and haven't been to the PO yet, my sincerest apologies. Stuff is all packed and will go out ASAP I promise.
Cheers!
