Thanks Bill. Maybe I'll let you ride it someday!
If you're interested in a bit of MTB history, I can talk for days...
You have probably heard of a company called K2. They are into bikes, snowboards, rollerblades, etc. Bought Pro-Flex in the late '90s.
In the early-days of MTB suspension (remember the first RockShox with Neon Pink decals?), telescopic forks were very prone to stiction if not serviced "regularly". A nice way of saying it. LOL
Pro-Flex looked at MX bikes with linkage forks and thought to scale it down. They teamed-up with motocross suspension guru Bob Girvin (that decal on the right leg used to say 'Girvin') to make this happen. The forks were surprisingly light compared to thier mass. Never any stiction. And STIFF. No flex under a lateral load (hard cornering). Its biggest shortcoming, though - travel was limited by its own nature.
In the rear, a Macphereson Strut design worked well with that fork. It too, was limited in travel by its nature.
Telescopic forks soon began to be more reliable, durable, tuneable, inexpensive, ... left this old idea in the dust. As rear travel grew, the last nail was driven. It's all about the history, brother! I do love the history. I hope I didn't bore you.
This one was born with GripShift and canti brakes but has been, over time, upgraded to full XT with V-brakes. Mostly 739 and 740 parts. I am thinking that the yellow cage needs to go. Too much yellow.
