kinda dumb question

[surfbum]

what is the difference between a ReTro valve and the RT pro valve?
i thougth the ReTro valves went to the RT original
and the RT pro valves were basically SS x-valves
is this right?

thanks

I'm pretty sure they are the exact same thing like a Xvalve and Emax valve are the same thing. Thought hte early serial numbers of one of them couldn't take ULT.

They ARE the exact same valve. with the exception that one sez thing an the other the other.
