I don't know when you started riding, Suspension wasn't available when I started riding either but thats largely irrelevant. This guys talking about 1991, which for the purpose of this thread is therefore 'BITD' and in 1991, manufacturers were offering suspension forks as an option on their bikes. Want an example? Check out this link to a '91 Orange catalogue http://www.indiansummer.ch/orange_1991_brochure.pdf
you could have your bike with rigid forks or Rockshox, same frame, no geometry correction. In 1992, Kona http://www.konaretro.com/articles/catal ... 2Page4.jpg
offered the 'Future Shock' fork as an option on higher end frames, same frames as rigid designs, no geometry correction.I can't be bothered to go looking for more examples but I'm sure that there are a few.
Mid to late 80's. Come early 90's, I don't doubt there were companies offering suspension options as you've proven so. We didn't sell Orange here in the States...and by 92, thats several years worth of suspension production and innovation within the mtb industry.
So we should all ditch our cantilever brakes or thumbshifters aswell, because modern designs are more efficient should we?
I don't know about you, but the thumbshifters and (some) of the cantilever brakes I have work just about as good as any modern trigger shifters and v-brakes out there.
In 1992 I put a Mag20 on my non-suspension corrected 90/91 Stumpy. Blew out the seals in less than a season, went back to rigid.
Of all the 'vintage' or older suspension forks I've tried, I've not been impressed. I ran full rigid up until...1999-2000 or so.
I've gone through a lot of vintage mtbs and a lot of vintage mtb suspension forks...My negativity towards them is just my personal experience.
Nobody said he was going to slap a pair of dual crowns on his bike. Whats wrong with a '91 frame, with a set of '91/'92 forks up front?
Nothing wrong with it at all.
If it is/was going to be an actively used trail bike though...the added weight, poor performance, and lack of reliability of those old forks would not be something I'd want to deal with.
If he's doing it for novelty/cool factor, then have at it.
I make mention of the longer travel fork based on they types of builds I've seen on the bikes posted here (seems to be a general UK trend). Modern parts and forks hung on older frames.
Perhaps I'm spoiled by my modern suspension and a retro grouch when it comes to my vintage builds.
