hello I have a 2019 rocky mountain instinct and im setting sag - I way 180 - 185 lbs with riding gear and to get sag at 25% I have to go up to 250psi
Is this normal? it seems really high pressure.

I dont have experience with that exact bike but the Evol shocks do require more pressure than the older shocks to achieve the same sag. That pressure does not seem out of line to me. Keep in mind that sag is just a starting point... you should adjust it from there based on feel and personal preference.

Also no experience with that frame, but setting a DPS Evol for a friend weighting around 70kg we had to pump it up to 215PSI.

Given your riding weight, 250psi does sound pretty high. This could be due to frame design, an issue with the shock or you are not setting the sag correctly.

Yeah. Necessary pressure depends on the shock and the frame leverage ratio. For a give shock, you'll need a different pressure depending on the frame leverage ratio. At 185lb I'm running 245psi on a DPS and Fuel EX.

Yes, pretty normal pressure for your weight ... this said, RMB suggest riding closer to 30% sag (shock). Should you wish to lower the pressure even more for a given sag, I would suggest you use position #7 (4 o'clock) of the RIDE-9 ... this is where the suspension produces the lowest leverage ratios (but also the least progression).

 

[jonod11]

thanks everybody, for the response. Its a new bike so im trying to get dialed in.

 

[jonod11]

I have tried position 5 and 3 but not yet tried 7 but I will give it a try for sure.

 

[Millennial29erGuy]

Also make sure you’re equalizing the positive and negative chambers as you inflate the shock.

 

[jonod11]

By this you mean cycling the shock 10-15 times at around 20%?

 

[Millennial29erGuy]

Yup exactly

 

[jonod11]

Ok then yes. I’m new to full suspension but I try to do my research. This is my first full suspension bike and have only had it about 3 weeks so I have a lot to learn.
