    Air spring

    What is the rule of thumb for setting the main air spring presuure in a Manitou Swinger 3-way?

    Check manitou's website or the manuel I believe it needs to have a certain amout of sag to work properly. So depending on your weight it differs.

    As mentioned, the Manitou manuals are posted on the answerproducts.com website for reference.

    But don't expect Manitou's recommended pressure settings to be of any value for setting the main chamber. Their manuals can't possibly take into account the different variables of required sag, suspension compression ratio (and which of the two travel settings you're using).

    You'll want to set this bike up by sag, and sag along. You're looking for something in the 30 to 33% sag range, or approximately 1/2" of the avaliable 1-1/2" available shock travel.

    I agree with Speedüb Nate's sag recommendation.

    Before setting sag though, set the SPV pressure to 50 psi (which is the lowest permissible amount). Then set sag to use up roughly 1/3 the travel. Then go for a ride and see how it feels. If you do decide to increase the SPV pressure, do it slowly (say in 5 psi increments) to see how it affects the ride. Of course, you'll need to readust the sag via main air chamber pressure after each SPV adjustment.

    If you set the SPV pressure according to Answer's recommendations, you'll likely end up with a very harsh ride. Answer recommends setting the SPV pressure to between 50-70% of your body weight. That may work for some bikes, but it's not right for the Hollowpoint.

    Or better yet, "see how it looks."

    If you're over pressure (overextended/under-sagged), the suspension will tend to compress the shock while spinning up a climb at a healthy pace, resulting in a compressive bob.

    Alternately, if you're under pressure (over-sagged), the suspension will want to extend the shock under those same pedaling condidtions, resulting in an extension bob.

    Once you've found the sweet spot, the suspension will "hover" in that area under most pedaling conditions.

    Another good point. Answer's "average" bike they have in mind when suggesting SPV thresholds does not have the dw-link suspension in mind. The Hollowpoint needs little to no threshold.

    Thanks for clarifying the set-up. I think I have the initial settings dialed. I will need to see how it rides this Thursday after work when I take it to the trails for it's 1st. ride. According to the Manitou manual, there appears to be about a 20 hour break-in period for the fork and of course there is a break-in for the swinger. So it seems as though the adjustments will be happening before every ride. Coming from a hardtail, this is something to get used to.
