Hi everyone.

Recently got my hands on an NC30 track bike and currently cleaning and tinkering with it. I was told it had already had the suspension set up for a 75Kg rider although the front feels very soft, so I'm dubious about this. However, I have a question about the rear shock. (see picture) It looks like a standard NC30 shock as far as I can tell, but I'm not sure, and it seems to have some sort of modification on the remote reservoir.

Anyone seen this before or know what it's for?

Yeah looks to be a standard nc30 shock with a different spring (standard spring is red) and compression damping added.

I have a similar setup on my racebike and it works very well, obviously condition and servicing is important.

Thanks mate. That's what I wanted to hear.
