This shock came as a spare with my Cannondale scalpel si, I have never used it so it is surplus. And I no longer have the bike. it looks to be in great condition. I have checked the air, it is holding 210psi and all the adjusters move and click in place. I do not know when it was last serviced, I had the bike for 18months so it's at least that long ago but never used while I have owned it.
