I have a 1973 Raleigh Sports and the rubber block pedals are starting to fall apart. They are not the type that can be rebuilt and was looking at MKS Sylvan Touring Pedals. I am not sure why I like them but I do. They seem to get great reviews. Does anyone know what the difference between the MKS Sylvan Prime Touring Pedals and the MKS Sylvan Touring Pedal Double Sided other than the name and about $8 on Amazon?

Thanks!

"high polished light alloy" vs "light alloy"

I saw that. It also says highly polished cup and cone leading one to perhaps believe they might be smoother

Probably worth the extra $8 for added longevity.

I have both and indeed, the Prime series are definitely smoother out of the box, whereas the standard model always benefit from a regreasing and adjustment, never quite as smooth initially, though after "overhauling" and some breaking in they are quite good, never had an issue with any of them. Also,the dust cap is nicer on the Prime version. And one last thought - because they are a wide pedal, which is great mind you, if using say 175 mm crank arms ( like me ) and a lower bottom bracket watch your pedaling through corners. On my 650b converted Fuji S12S absolutely no issues - on my Rawland Stag, specifically designed for 650b I can easily strike the pedal without trying too hard. Of course, it does not help when you ride different bikes and forget but having more ground clearance never hurts!

Thanks to all for the input. I pulled the trigger on the prime model. I even found a cap wrench on e bay for $7.

If you're talking about these: XLC Retro Pedals, 1 Pair 9/16" Silver I've used several pairs of these on my bikes & can find no real difference between them & the more expensive MKS.
