What's the difference between the models?
Google image them for pictures, but my understanding of the basic rundown is:
PRST1 - the original "PReSTon" - quad linkage front end with dual linkage rear end, "plus fours" forks made with flat folded welded sections. Innovative stuff like the "big gripper" QR's on the wheels etc.
PRST4 - same "plusfours" front forks but quad link "virtual pivot" rear end - same "big grippers"
JW2 - dual pivot rear, cheaper to manufacture tubular "T-fours" fork using the same quad link, conventional drop outs so no big grippers
JW4 - same "T-fours" quad link front, but with the quad link rear end from the PRST4 - same conventional dropouts.
I think the PRST1's or some models may have had magnesium main triangles at launch but were replaced with alloy due to longterm durability
I think the entire range were only manufactured from around 1999 to 2004 - early models had canti studs, later ones were disc only - all the main frames were basically the same with the "trim" being sorted through the equipment spec'ed on it.
