Help setting up shocks PLEASE

set sag in normal riding position, so the attack (riding out of the seat).

weight has nothing to do with anything. just add air to give the sag required.

as to how to set up the fork depends on what it is.

( disregard most of the above if the fork is a coil fork with air assist).

It it's an air only fork, and your weight is at the upper spectrum of what is allowable for the fork, you may not be able to achieve full travel (I have this on my forks - coil conversion required).

does not make sense.

I think what they are trying to say is that if you weigh 18 stone and set sag for 25%, the forks will be so solid because the air inside is already under alot of compression to resist your weight, that it takes alot more force to make the forks compress and full travel will be very hard to achieve without the internal pressure being too high for the forks to take it. I think at the extreme you therefore have to set for more sag to start with.

Does that make sense?

The sag compensates for this though. If it is already moving 25% with your weight, it will behave similarly to a lighter rider with the same sag. It takes more force, but you have more force ie your weight.

This is why going on sag levels the playing feel. Forks and shocks can happily handle the max quoted pressures. Set your sag, note the pressure.

But look at the dasmpers too.

This. I had air forks when I was 18st. Set them up as per the guide on here and they were buttery smooth over everything. Wish I had the air version of the Pikes on my current bike.

Nicklouse, you've been very active in my post about the issues with my forks, so I'm sure it makes perfect sense to you!

You do adjust sag though to your preference. Add more if you need it.

Basically you can not equate pressures fork to fork ie 100psi in a Magura will behave totally different to 100psi in a Rockshox fork for the same travel.

25% is just an average starting point. DH riders with more travel may want to up it to 30% or oven 40%. XC riders may like just 15%.

In the end set it to what works best. Rider weight is rarely an issue unless you need more pressure than the maximum pressure.

The only other issue is that some shocks with small volume chambers ramp up more quickly. But this is factored into safe working limits.

Also worth adding that the negative spring can be used to tune ride height and feel too.
