I assume this isn't the Viper you're looking for- it's all I could find at a quick glance through my archives. I'll keep looking when I have more time.
Here's another strange one- Saracen with front/rear linked elastomer suspension and telelever type fork.
I can name several professional engineers that prefer pencil and paper- race car designers Adrian Newey and Trevor Harris immediately come to mind. A computer is just a tool- that's all. There is no such thing as computer designed. I believe the quote is "Computer design is quite often merely...
That has to be one of the best posts I have ever read. Having owned my own components manufacturing company and done some consulting work I couldn't agree more. There is nothing that is easy in the bike business and a good design engineer that understands manufacturing is worth their weight in...
I'm amazed they were able to keep it under wraps for so long. Must have been something like "The first rule of SB66 is that you do not talk about SB66..."
While I don't normally care for curvy tubed bikes it certainly does look nice- it's an elegant compact design that appears to be well...
Nah, it's not weird at all- a lot of those cars built in the 70's were super cool and very inventive, especially the CanAm cars. Some of my personal favorites were the Shadow CanAm cars designed by Trevor Harris (same guy that did the RockShox LTD bike, all conquering Nissan GTP cars and...
Which means I probably know just enough to be really dangerous... :) I figure why make things that already exist? I don't see the point in making copies of existing designs that are already pretty refined. It would certainly be an interesting project...I'll codename it Project Deathtrap. Now...
Found the quick sketch I did (it's far from exact) to show the Telelever/SaxTrak fork idea I figured out for a short travel (120mm) 29er. I really don't think it would work for longer travel than that.
The idea is to use a space frame construction with a wide control arm at the front to...
Found a couple more pics of the Ribi fork I had saved-
The RC250MT has kind of a hybrid of the earlier steel fork and the later version monoshock Aluminum fork
This is probably one of the best pics of the monoshock version
Yep- they were one in the same. I used to know Dan White pretty well- super nice guy. Got to tour their facility in SoCal. They were also the guys behind the Rotec bike- I remember sitting in Dan's office and he was telling me about the design and how it would pivot around the BB shell, etc. I...
I used to have a huge motorsport/engineering library and I've been collecting all kinds of suspension design info since 1990. Sadly I sold most all of my books when my son was hospitalized several years ago but I still have tons of pics and info on my computer (and in my brain- hopefully.):)...
That's one I haven't seen before. It does remind me of a Collier. I do remember reading a patent a long time ago that showed that jack shaft chain drive system- I think it was called Traklever or something like that...
