Zipp 303 XPLR Wheelset

I believe I picked it up on the TR podcast where Jonathan was talking about SBT gravel. If memory serves correctly he built up a gravel bike from Keegan’s garage and referred to grabbing a set of yet to be released wheels (assuming Reserve given Keegan’s sponsors) which I think he referred to as being wide. Could have been the 40/44 but I feel like those were released before Steamboat. As I said very much a rumour.
