Interesting thought... it is a junky piece so I would be intrigued to know the answer to this... Everyone I know bought an Ohlins ..but at some $350ish IIRC then it would be nice to have an option....
It isn't rebuildable. I mean it might be if you start taking it apart from the sides, but I am just not going to do that. If I find I need it harder, I will just get the Ohlins.
