I took the rear suspension unit off my NC30 and noticed that it looks different from another unit I got from eBay.
The adjusters and the overflow pipe seem to be on the other way round, and the thing sticking out of the reservoir is weird. Has it been refilled? Is this some kind of extra adjustment?

Anyone?

looks like its been regassed , mine has a valve in the end the same , they have to add the valve as there is no other way to regass it otherwise i belive , mine was done by brook suspension

If the one with the reservoir valve hss been refilled it should be in better condition than the other one, so that's the one that'll go back on. Thanks.
