The general rule of thumb is that when the rider is riding on a flat and straight surface, the shock compresses one-third of the way through its total travel. That way, when the rider hits a bump, the shock can compress two-thirds of its travel; if the rider goes over a rise in the road, the shock can extend one-third of its travel and the wheel can stay in contact with the road.
Morning Chris, Mick and Larry.
Larry, the Dallas Cowboys want to thank your Lions for doing them a solid yesterday.

Truth ! Our roads suck in greater MN because the metro folks like to spend as much as they can for cool city toys (billions for light rail) and "other" programs. Our freeze-thaws raise hell with everything out here.
Thanks Bob-O
If sag were "under-set" to allow for a softer ride .........wouldn't the stroke just travel further before hopefully not bottoming out on a big hole, or it is a mistake to allow for more travel "momentum" and resulting bottom out "bang" by under-setting sag?

Oh, and Stan, sag also determines the chassis geometry angle. With less shock sag, the rear of the bike will ride higher causing a quicker steering response. The more shock sag, the rear of the bike will ride lower and improve high speed stability. These are General thoughts Stan and you set it up for you and your preferences.

Thanks Gents- good info and common sense when you think about it.
Plus, I like the idea of my piston being "centered", allowing me to stroke it in either direction for the best ride, for my partner too .....

An inch or so in each direction???

Biggest issue I have here is the frost heaves and expansion joints. They're like mini speedbumps on the highway. You hit those at 75 MPH and it plays hell on the suspension, either bottoming the shock, or bucking you off the seat because the spring is too stiff to absorb it. It's a very fine line of adjustment to reduce the severity of those hits, and then maintaining an acceptable ride on good roads. That's where more travel really helps. 3 inches isn't enough. Hell.....sometimes 5 inches isn't enough (That's what she said!). But on rough roads, more is better. I ran 13.5s which is the minimum I would do. 14s would be even better.
I appreciate all comments on this guys, and the help "thinking it through". Greg, Bob, Chuck, Russ ............. and yes, AL.
