Default Re: Hyperpro progressive springs - air gap & forkoil

I was asking them this, helpfully they won't tell you the cSt rating of their oil or the VI. Obviously they don't consider Joe public qualified to look at numbers more complicated than multiples of 5.

There ya go. Credit to Peter Verdone where it's due. As you can see the SAE viscosity has little bearing on the behaviour of the oil.
