Retro spd's

[Rio]

I use 737, 525 and 540 at the moment. Would love to try an alternative for Shimano though. Anyone can tell me how the Ritcheys work compared to Shimano SPD? (any of the above)

 

[cornholio's RC200]

535s on all mine except the Vit which has 747s. As Paul said, right first time for Shimano.

 

[Rampage]

+1 for 747's.

Was using them until recently when I switched to a single sided Wellgo Magnesium pair. OK not really retro but a fairly light pair of pedals at 238g for the pair.

What are the like, do they have float? Shimano cleat compatible? I've found them for £40 on the Internet!
