Sorry for the late check-in people
If you take a look in our 240 section, our spring offerings are listed there under suspension.

But, it breaks down like this -
* king fronts: -30mm. 165lbs
* DVS fronts: -40mm. 250lbs
In most cases, both are well suited to the normal king springs rear.
Drop me an email if you like. Happy to talk about it with you.
