Yes, thats what Im worried about bro! The bike I have it on is 160mm with a 200eye to eye. I weigh 200lbs and with the roco a smooth 155psi was a little on the hard side. The vivid says 275psi max but for me to get a balanced ride that didn't bog into all the travel I had to keep going up to 350psi. I rode her hard all day Sunday at 350psi and it felt awesome but, yes Im very concerned with 350 as for it being way to high. I ordered the rear valve adaptor for the piggy back's pressure so, Im very curious to see if the piggy backs pressure is up to par. Some pictures of last sunday at 350psi and no explosions yet, ahhahha http://www.pinkbike.com/photo/8127001/ http://www.pinkbike.com/photo/8127225/ http://www.pinkbike.com/photo/8127056/ http://www.pinkbike.com/photo/8127099/ I dont know what to do really as I purchased the shock not knowing it would take so much? It riding good at 350psi but if it will really break it they need to advertise explaining much better. I have to try looking for a link to e-mail scam or rockshox to ask some questions.

I've just recently got a vivid and coming form a roco air its been tough to set up. Im still fiddling with its settings but I have it feeling 80% good at the moment. The biggest difficulty I had was with the overall air pressure and ending rebound. Alos the air pressure determines the sag which seems to be way too much at normal settings. My roco I was previously on for my weight and bike I used 155psi in the main chamber and 220 psi in the piggy back. This gave me perfect sag and an outstanding overall ride that was plush but never bottomed out. The vivid on the other had for same bike and of course same weight rider, I had to push it up to 350psi to finally find a sag point that was rideable. Even at 350 its a tad softer than what I like. Then with the ending rebound on the 3 setting the shock felt completely horrible. It would pack down when riding and not return to its full length feeling very odd. Finally I ended up opening the ending rebound completely and it now feels decent. The rebound setting is marked "M" so, I'm assuming I might have to lower the shim stack to take advantage of the ending rebound for my bikes leverage ratio. After only being on 2 ride though I have to say the shock is awesome. Once set up to how you like to ride it will feel like a coil or pretty close and ride very smooth! The roco was much easier to set up and it also rides superbly coil like! Im still testing the overall ride but I have high hopes for the vivid, especially since you can purchase any extra part needed to internally adjust your shock or service it, unlike the roco! RideOn!
