Rear Shock Question

I am looking at upgrading my rear shock on my 2008 Giant Reign X2 but I don't know what exactly I have as far as configuration. It is the factory default but I don't know the measurements.

Question 1 - The rear shock is a Marzocchi Rocco R and I'd like to replace it with a RockShox Vivid 5.1. The vivid comes in 267 x 89mm (10.5 x 3.5), 240 x 76mm (9.5 x 3.0"), 229 x 70mm (9.0 x 2.75"), 222 x 70mm (8.75 x 2.75"), 216 x 63.5mm (8.5 x 2.5"), 216 x 60mm (8.5 x 2.36"), 200 x 57mm (7.875 x 2.25"), 200 x 51mm (7.875 x 2.0"). Which one fits?

Question 2 - Has anyone used a Vivid 5.1 and would they recommend it or something else?

Thanks in advance.

pull your shock out and measure the free eye to eye length, there is usually only one matching stroke for a given i-i, expect the 7.785" i-i shocks, they come in both 2.25" and 2" stroke.

Re which shock, depends on what you do with the bike... a good all rounder for that might be a roco TSTR air, save some weight too.

I have a brand new rockshox vivid 5.1 only has 1 week of riding on it. It dosent not fit my new bike i have all the hardware and two springs.Its 7.785 x 2.25. Shoot me a pm if your interested.

Vivid's are solid shocks, I ran one for a season on my old bike, it never gave me an trouble. I'm running a roco wc on my new bike, so far it's pretty solid either or would be a good pic.
