I'm thinking I may have an issue with my new VIPR shock, when I first set it up I was running only 100psi to get 17/19mm of sag. Now when I set it up I'm looking at 150/160PSI. But, then again I maybe just forgetting the initial settings as I did it a month or so ago.
Im around 75kg, what weight / PSI is everyone else running ?
Cheers.
Hope this helps: www.bosmtb.com/pdfViprChart.pdf
I have a blur ltc and run it at about 15/20 less than the chart says.
THanks, I had the manual but not the "Chart".
My mistake with not enough little air. It runns really nicely now, its quite nice isnt it.
Cheers.
At 105kg and with a stroke of 57mm stroke on 155mm travel I have 275psi in mine versus the recommended 285psi. I have to say that I love mine to bits and that’s having come from a CCDB, but I can see it wouldn’t be to everyone’s taste. I think if you’re heavy and/or tend to hit things quite hard, it’s a great step forward in performance. It doesn’t blow through its travel like the 2011 RP23 I had did (although I hear the 2012 RP23 is more controlled in this respect) and when matched with the Devile fork it’s even better.
The Vipr has a lot of compression damping which helps it to use only the travel you need for the terrain and as such it may feel overly stiff for lighter riders. For that reason I think that the Vipr is probably more compelling when used with the Devile than not; you could use the Devile on its own I think and have a great performing set up, but I can see people trying to use the Vipr with a Fox or RS fork and finding it hard to get the bike balanced front to back. The Vipr would be holding on to its travel while the fork was working through its travel and consequently the bike would feel steep and sat up rather than into its travel.
But in combination the two are amazing; the bike feels so well balanced and this gives an added sense of confidence that there aren’t going to be any nasty surprises in the way it reacts at speed. I still think the coil CCDB is in absolute terms better, for instance you can tweak the dials to give more pop when you want to launch the bike without the tendency for the bike to buck you off, but this is a small sacrifice when the Vipr saves over a half a kilo in weight.
