When I worked in a shop during the summer of 1993, a Proflex rep once visited us and had this bike with him. He let each of us take it for a quick test-spin, and I remember really
liking the ride. Sure, this was "primitive" suspension technology, offering barely 2 inches of travel at each end, but it was one of the first (and still only!) full-sus rigs I've ever pedaled. I remember that there was very
little pedal bob or brake dive -- overall the bike felt really solid, and I wanted very much to ride it on some nice single-track.
Ever since, I've had a soft spot for this bike.
Proflex developed one of the earlier full-suspension MTB designs, and -- unlike most other brands who seemed to try something new each and every year -- kept the same basic design and simply refined it year after year. I think this basic frame still is one of the longest-running designs, in production for something like 5-6 years (that's a guess?) until K2 bought up Proflex early this decade.
You can sometimes find these bikes used for quite good prices, but unfortunately the yellow MCU elastomers have all either hardened or turned to mush, and working replacements are extremely hard to find. A few years after the bike pictured was produced, Proflex moved away from MCU springs (which I still think are a great, lightweight, no-maintenance design!) to steel coil springs with hydraulic oil dampers. They offered retrofit shock kits for the forks and rear swing-arms for the earlier MCU bikes.
When I tried to build my own full-sus frame
a few years later, I modeled the rear swing-arm after the Proflex design, even building the MCU shock unit using Proflex spare parts which were available back then. It worked, kinda, but the rear swing-arm wasn't cross-braced well enough, so it bent sideways at the first strong pedal-stroke. Project scrapped, lesson learned!
I still want one of those old Proflex bikes, though!
