5th Element Air Shock. Service/repair

As usual, thanks in advance for any guidance.

An older SC Superlight has a shock issue. 5th Element air shock which is 7.875″ eye to eye and 2″ stroke = 200mm x 51mm.

So, anywhere still likely to be able to service/repair?

Alternatively, any good vale replacement shocks to consider?

Thanks.

7.875″ is 200mm, so there are options available for you for a replacement read shock:

Forumite I_Ache used to service these apparently, I don’t know much about where else you could try.
