Zeb Ultimate 170mm airshaft

[RustyMojo]

Before I buy a new one, does anyone have a Zeb Ultimate 170mm airshaft (29er in case that still matters). I’m running 160 with a mullet setup on my rail and want to give 170mm a go just to help raise the Bb slightly. Thought I’d chuck a wanted ad up before I button off buying a new one

Thanks
