Lovely machine.
I have a 957, also owned a 954 (thanks Chris). Both wonderful, got me into biking. Ridden the 957 more than my "new" bike recently. Its amazing how many older riders point at you and say "Bloody hell, its a Proflex!"
I have normal forks on the front (Rockshok Psylo's - nearly as dated as the Proflex!) and the Noleen spring shock on the rear and its still a great ride. Light and responsive.
The front forks by Girvin were called Vector btw. Had them on the 954 but the elastomers (front and back) stiffened to a point where it effectively became a rigid bike.
Where did you get the Risse unit for the back?
