nice find

bet if you sent them fork springs they would copy them but adjust the rates.

I gather they only need dimmensions and rate, can be made in linear and progressive ???
About to test them out.

they might have to make a mandrel for the fork ones so would more than likely need a spring to take measurements from.

don't bother with progressive get linear.

We have a spring maker i Norway, you can send them your spring(s) and say "I want this(them) 25% stiffer", for new bikes it's not really a problem, there a lots of on the shelf springs, but for classic racers it's gold to know a company like that. Oh and if your have a good ruler and vernier callipers they will ask for the right measurements over phone.

i have a faulkner on my shock too.
a thing to consider is that they're mighty fat and heavy compared to
the (pricey) bike-specific alternatives.

Further info/update following mails today. They no longer do fork springs as the range of tooling has become too expensive.
The outer diameter of a standard 2.25" damper spring is 3.25", as m'baubz suggest's a little on the fat size, very difficult if you have limited space.

Sadly for me though is I need a springwith a taper i.e different diameters top-bottom.
