Tubeless conversions? Rene Herse Ultralight tires? Ceramic bearings? Carbon steerer tubes? Hollow pin chains?
Why not 2 categories?
in that 4th photo, the guy is riding with a 1998 M739 chainset, so they can't be that hot on the homologation
It's always a fun event and pretty relaxed... Personally, I'd rather see old bikes being ridden than worrying too much about specific parts not being quite the correct era.OK, I got a response back, and they sound pretty laid back about the definition:
Hi James, the bike sounds suitably "Retro" to me. As long as the main frame is circa pre 98 then we're happy. We understand that tyre, grips and the like will fail so you have to update.
Thanks Matt
