The V11 Suspension Pressure Thread

[rexdelmolvo]

My V11 will be here sometime next week, and something I hadn't seen yet was some kind of logging for everyone's preferred PSI for the suspension chambers on the V11. While Inmotion has their recommended values, I know a lot of folks have had to tinker with different pressures to find what offers the best ride for them. If you ride a V11, what's your positive/negative chamber PSI, your weight (w/ full gear), tire pressure, and what conditions are you riding in? On or off-road?

I might make some kind of a spreadsheet to sort this info when I get the time, but I'd love to hear what you guys have found has made for the best experience on the V11.

I think tire pressure is important to a degree. 
 

I am still dialing in.

 

positive - 100 Psi

negative- 50 psi

tire -  35 psi

weight - 160 lb 

mostly on the road. I would need to increase it if I was going to hit some big drops.

Yes, it is. Totally forgot to list that, gonna add it to the OP

positive - 200 Psi

negative- 110 psi

tire -  variable due to my leak/seepage

weight - 255 lb

I have a text document filled with dates and the various shock pressures tested, with the best one in bold. The problem is that in the beginning the best was something like 120/0psi, which then slowly moved up to 165/90, and then again down to 155/30, and now as the weather got cold, to 160/50. (Add 5-10 psi per -20•C)

0 psi on the negative gives a lovely instant rebound and easy compression over roots, but smaller movement at road imperfections at speed is more harsh.

90 psi negative was good for gravel roads, but the suspension travel was shortened making it too stiff at roots.

30 psi negative is a very nice and smooth, relaxed behavior, and has a bit of that Cadillac feeling. When the bits wear and friction increases, this works the best.

If the friction is manageable and the sliders in good order, 50 psi negative really is the best. It’s the most sensitive on cobble stones, and still takes roots well.

 

 The lower main chamber pressure must ALWAYS be adjusted for a correct riding height! Not by a chart or recommendations, but standing on the wheel and measuring the sag. Too high and it can pogo stick you off. (Bottoming out is not a danger to the rider or the system.) Measuring is easy for example from the handle to the board cover. Go for 35mm (1.4”) sag for all use cases. Lower psi in the negative calls for lower psi in the main chamber as well.

_

Testing the shock pressures only on curbs or roots gives very different results than riding the actual conditions you will be riding. My riding weight is around 108kg, tire at 33psi, and I ride maybe 30% on paved roads, 50% on gravel/dirt, and 20% on gnarly MTB paths.

 In the very beginning I didn’t know how a good EUC shock would feel like, so I aimed for emphasizing a floaty behavior. It didn’t work very well off-road, so I then went to the other extreme.

 What I’ve learned though is that as the gap between the suspension sliders and the supporting bracket increases as the slider bits and the bracket coating wear out, the structural friction of the system increased quite a bit. This fundamentally changes how different shock pressures function.

 I’m hoping to get more detailed comments from Inmotion regarding the expected lifetime of the slider bits and the bracket wearing out.

I've been riding at 160/50 so far, but I think it's a little too soft. I'm still fiddling with it.

Im a 200lb rider geared up and i run 70 psi in the top chamber and 140 psi in the bottom.

I think different machines will have slightly different setting even for the same rider though.  As others have said their preferences have changed over time as the system gains friction and breaks in.  

Plus some people prefer more bouncy other like more floaty, personal preference will play in a little bit

I'm currently using 25 psi in the top (negative) and 70 in the bottom (positive).  I'm about 120 lbs.  This setup gives me exactly 3.5cm of sag.  In other words, when I stand on the EUC, the pedals drop 3.5cm.  I set this up this way based on mrelwood's advice.  It feels good but I haven't ridden it enough or tried enough other settings to say it's the best, but I think I like it more than the few higher PSI setups I've tried.

By the way, I know George from the post above this one has changed his settings to 30 top / 90 bottom from one of his more recent videos.

I'm interested in how other lightweight V11 riders have their suspension setup.

Been doing mtb trails for a couple of years now on my 2 v11:) fking nice.

finally got at good pump. (Must)

my bike dealer called it a shock bike pump. Good for accurate pressure.

82kg 

For mtb trails

tire 2bars

bottum chamber 130-140 psi

top 70-75 psi

 

the rest is skillz. No pads.

you lose the comfort og everchanging stance.

Since the ancient thread was necromanced, I think it's good to remind people not to overinflate the shocks because you think you lose some when detaching the pump:

 

 

Btw, been using 160/60 or 170/70 psi for a good while now. I weigh 105kg and ride a combination of street, gravel, and off-road.
