I wasn't suggesting removing all technology, as I agree that wouldn't work even if I wanted it. I just liked idea of a parallel low technology track fighting the good fight against pointy helmet disc-wheeled ten rider weeknight TT. Something odd just for fun, like the 24 Hours of LeMons¹ on beaters from the shed.
I'm kind of aware of Keirin from watching track, but wasn't aware of the depth in the local market. That Chris Hoy video was great, thanks!
