Just dematerialised one during a service – can I find it…can I heck.
Foams were wasted so pumped up £16.80 for new seal kit. But tell me – what do those very weak springs do, I can not believe they add much to the wiping ability of the rubber.

You may have explained why people buy aftermarket polyurethane seals like Enduro.

I've found that when I've pulled a set of Marzocchis apart, you can get them back together pretty easily if you take the springs off, but it's the devil's own work if you leave the springs on. So I reckon they work.
