Thanks bubs, I guess my question is more based around how to set the sag, is it just a case of adjusting the air in them both?
Yep.
Your LBS should sell shock pumps, they’re not expensive and can handle up to 300psi or something ridiculous.
Measure how much stanchion you have showing, eg 130mm and if you want sag at 20% you’ll add or let out air until there is only 107mm of stanchion showing with you sat on the bike, the rubber rings that shocks and forks come with are invaluable for this but you can improvise with a ruler and string tied lightly around the stanchions….heard of people using cable ties but I would be worried about marking the stanchions.
….and that’s it really, do the same for the shock.
The travel in the shock is much shorter in relation to actual rear wheel travel but don’t let that confuse you, just work on what amount of the shock stanchion is exposed with the bike unweighted (would be 50mm on a 200×50 shock for example) so 20% sag leaves just 40mm showing with you on the bike….experiment with what feels best, some people prefer up to 35% sag at the back but I find that a bugger to pedal, sweet spot for me seems to be 25% front and rear for trail riding….don’t worry about actual pressure figures, if they’re in the fork leg or in SRAMs website then just use them as a guide, ultimately it’s the visible/measured sag you need to be concerned with, the pressures to get you there vary from person to person obviously.
