Hey guys, I was starting to dial in my 2009 Marzocchi 66 RCV last night.

I got on with my full face helmet and clothes and made sure that the fork doesn't have air in both legs. I sat on and got 1.5" of sag.

1.5" = 38.1mm.

The fork is 180mm of travel. So 38.1/180x100 = 21%of sag.

When I am reviewing the Marzocchi Pro Tune document, they state:

The amount of sag needed depends on your riding
style, basically the more travel your bike has,
the more sag you can run. As a starting point we
suggest-
• Cross country (4")- 15%
• Trail riding/All mountain (4-6")- 20-25%
• Downhill/Freeride(7-10")- 30-40%


How would I be able to get 30-40% of sag on my fork if I can only get 21%?

Any suggestions?

Thank you

Did you ride the bike? Personally sag on the front end means very little to my tuning process.I set my spring rate to give good bump compliance w/o dive and achieve @ least 85% travel. Trying to hit a target number could result in a very soft front suspension. Run what you have and adjust the spring rate on the trail.

OP, make certain you get ALL the air out, which means compress the valve and push down on the fork. If you are very light, then it may take some oil level and weight changes (which I think is what your link is mostly about).

I wouldn't be too concerned about sag as long as it rides like you want.
