OG Classic shape is not that wide and not that heavy really.
The very squared off edge with a medium width and wide surface area is good if you want that sort of thing, with the cutaway side to reduce weight as well.
If you cut the sides off a conical full that would be almost the exact outside riding shape, or you could say a squared edge design that is almost a fat cut away tablet wheel or a cut away double sided lock in, if that makes any sense.
They also come in original formula and Formula Four, so you have the two options there.
If you compare 54mm wheels in all options, the OG Classics:
* have the widest surface contact 22mm, bar Conical Full same at 22 and Lock ins at 22.5mm
* are 32.5 wide, so really only the Radial Slim and Tablet being thinner, and Conical just scraping in at 32.2 wide, with all others being wider by a mm or two.
All round they could be the best overall size and shape for people who want that sort of thing, but you do have lots of options now, especially once production ramps up and they do make more sizes in everything again.
Currently the 55mm version of the F4 and the 52mm version of the classic urethane are widely available that I have seen, with some places hinting at the F4 52mm is coming soon.
I reposted the Spitfire card that someone else had put up a few pages back, that has all the current specs, including Classic, OG Classic, Lock Ins, Tablets, Radial Slim, Radial, Conical and Conical Full.
When opened it does show all the specs clearly for me, but might be too small to see on other screens.
