has anyone seen F4 OG classics in any size other than 55?
With delays in production, they have only been doing runs of some wheels, so right now the 55mm size might be all that is out, with more on the way, but who knows when that might be.
It does seem that they are getting stocks up quite quickly, so it might be sooner than later, but exactly when, I don't think anyone really knows, hence no one able to answer your question earlier.
As per the Spitfire site and has been shown here as well, there should be 52, 55, 58 and 60mm in those, but from the product card that is included with Spitfire wheels from pre covid it shows OG Classic Formula Four in sizes 52, 53, 54, 55, 56, 58 and 60mm, so at some point in the future there might be all sizes.
What size were you hoping for?
