sheesh that was long read...
I had a chrome Pro Racer in 85ish and would love a new version of it with a 21" TT but OS legal. That'd be interesting - a NS 1" Threaded Headset - Caliper brake 4130 Crmo F&F. Bet that'd cause quite a stir, but to me that's a proper replica bike. These "replica" modernised bikes are cool and "up-to-date" with their internal headsets and euro BB's but the OS touch needs to be more authentic I reckon. Most of these new releases are "retro" and not "replica" in my books.
Heck, after Kuwahara's return to BMX it would be awesome to see Hutch back too - perhaps that bloke needs to talk to Dibly from UKunknown for some tips...
