But that stuff was still technically (bullshit) commercially available.
It's fucked anyway, since you have to be a pro to get on the bio passport and you can't have a crack at the Hour without being on the bio passport. So, all this bullshit about 'anyone can have a go' from the pros is just that.
Probably goes out of the window for hour events, as I doubt I'll be able to buy a track Bolide any time soon (not that I could ever afford to).
Plus they can just do the same as they did with old UKSI stuff, huge lead times and ridiculous quotes.
