I had a ~92 Prestige, it was damn light at the time (XTR, Alu forks etc.)
Very nice bike, but my '91 RM Altitude replaced it and there was a world of difference.
I then in ~1994/5 got a '92 clockwork. It worked, it was nice to commute on and doss around on.. It had horrible forks (them PACE rigids), the frame was solid but dead and altogether was shite offroad, not a patch on the Prestige I had.
Of course I was quite light back then (10 stone give or take 1/2 stone), very fit as well.
I guess it just didn't work for me at the time.
The best thing they did was sell pretty cheap frames and let you fit what you liked on it.
I must say the Alu-O is also pretty shite in the scheme of things.
It's the Early 90's version of On-One in my opinion (the style of company and setup)
They are both companies doing very well as far as I can see, which is not bad going for a UK company.
On my old rigid "shite framed" Clockwork, I substantially out-smoked a modern Fat Scandal Inbred Rascal On-One (29er, front sus), on my long commute home last night. This was on a long badly maintained road through North London with speed humps, long gradients up and descents. Plus dodging maniac drivers. Not bad for an old clunker.
I agree on your opinion of On-Ones.
