[Closed] Reverb Stealth cooked, is this the right size for a 2016 Capra?

Hey,

just got back from Wales after a weekend riding. My screw cap has worked it's way loose and i noticed it was up underneath the saddle at the end of my ride. On closer inspection when I got home some crap has got in there and scored the shaft :/ Bad times.... Looks like I'm going to need another one so was just wondering if this is the correct size for a 2016 Capra?

I know it's 36.1 and 150mm, but not sure the length. This one is 440mm. Is that right? Not even sure where that measurement is on the post.

Thanks

Rob
