Could anyone guess a date for this pretty old Edison cyclo-cross machine?

I see there's not a tubing sticker. That would help a lot. Anyways, what size seatpost? What's the frame spaced at? If it was 126mm it would most likely be pre 88-89, 130 after those years. Unless it was respaced by a previous owner.

Very sweet looking cross survivor. Either a big refinish or its not seen much action. Looks like a fair bit of tyre clearance at the back between the stays. I would say thats more 90s than 80s by the space for what I'm guessing would be x35 or x38 rubber.

Cyclocross as a sport has restricted tyre widths. Back then i think it was 32mm and at some point more recently increased. Maybe to a whopping 33mm!

Yeah, 33mm (measured) currently. Local leagues weren't wedded to UCI regs, thankfully. The old rule was 35mm for seniors, big lads and chepskates (I ticked all 3 boxes). I was one of the few riding 32s in the London&SE league - because thats all I could squeeze in between my chainstays on my 80s steel cross bike.

And people seemed to be selling a lot of 38c CX tyres - almost everyone on alu cross bikes used them. I never saw any scrutioneering in my years of CX...maybe if I'd been a lot better than I was they would have checked my tyre width.

Thank you for that info . I didn't know that you could use fatter tyres outside of UCI events.

My knowledge is pre disc, pre US thirst and influence on UCI cross regs. I think nobody really cared up to national level champs - if you were good enough to get there then be prepared for a closer interest in these things. Carthorses like me racing for 90th place in a local league ...hard to believe cross was struggling a bit 20 years ago. They let 26" MTBs in to try and attract more entrants...no such trouble now.
