I have a Stöckli MTB with Manitou shocks but they are losing pressure...is it advisable to re-pressurise them yourself (do you need special high pressure shock pumps?) or is it better to have them done by a professional.

(Reason I think maybe professional only is that no pressure guide is printed on the shock itself)

Thanks

This is exactly as simple as pumping up a tyre although you will need a high pressure shock pump. You will find pressure guides for your hardware on the internet but the best way is to adjust the pressure to achieve the recommended sag for your fork or shock (probably 25% of maximum travel) Search youtube for fork sag for instructional videos.

If your shock is losing pressure at a fast rate then you will need a service with seal exchange.

Cheers
