Ultegra pedals? PD-6610? R600? Eh?

I see both of these numbers advertised for new Ultegra pedals. The pictures look the same. Are they the same pedal? Shimano’s website only shows PD-6610. What the heck is an R600?

I think R600 is the technical term for the Ultegra line. PD-6610 is the Shimano part number. The part number PD-6610 corresponds to the R600 SPD-SL pedal.

The PD-R600 is last year’s ultegra pedal - doesn’t say Ultegra on it, though, just Shimano. The PD-6610 is the newer version, says Ultegra.
