On your Reign ½" shock movement equals 1½" suspension/wheel movement.

Eactly.if your bikes axle is allowed to move 6 inches aka six inches of travel. and you have a two inch stroke on your shock then the shock will move half an inch for every two inches your axle moves.

the amount your axle moves will always equal the amount the stroke moves in terms of percentage.

oh lol you probly thought the quotation marks meant inches by 1/2 i meant 50 percent.

No, it most certainly doesn't
It all depends on the leverage rate of the frame it's self.
most modern frames use a rising, or more progressive rate, with a more linear compression rate coming from the shock it's self. Meaning the frame does more of the work then the shock, so the shock's adjustments and damping will have more affect. But all companies have their ideologies, and different style bikes use different rates. FR tends to be more progressive, while DH more linear.
Eg. 33% sag on my M9 is .9" stroke on my 3 inch stroke RC4. The M9 has a very linear compression rate, and it still doesn't have an equal travel to stroke ratio.

Ahh, fack. Sorry. I believed he wanted the simple explanation to leverage ratios.

Here on a Legend mk2 you can see that 25,5 mm shock travel (33,5%) equals 36% wheel/linkage movement.

 Posted: Aug 30, 2012 at 17:11 Quote Will a shim from a Vivid fit on a Vivid Air? My buddy had the vivid with a High tune shim, and I have a Vivid Air with a medium tune shim. He has a Scott Voltage FR which can run a medium tune, unless he decides to change the rear travel from 180 to 160 (in which case he needs the low tune to be able to switch back and forth). I have a Commencal Furious VIP which can run either a medium tune or a high tune. We are hoping to trade shims so that his vivid will become more active, and so that my Vivid Air will have better high speed compression damping.

 Posted: Aug 31, 2012 at 3:15 Quote I think so, i think the compression units are the same so it should work, you'll have to change the whole shimstack to get the tunes swapped though

 Posted: Aug 31, 2012 at 7:39 Quote No way they're the same. That would blow my brainz out. Just highly unlikely as the ramp up is very different between the air spring coil spring. So it would need a different shim stack to get the correct amount of compression. Call SRAM? But why bother changing it at all? I would like having a firmer shimstack in 160 mm than 180 mm as I clearly would put it in the 160 setting for better pedaling, more support and an overall quicker feel to the bike. Some of the difference could probably be adjusted with the comp adjuster anyway.

I think he wants to change it becuase right now his bike feels more like a hard tail in the rough stuff than a gravity rig. I've tried calling sram, they don't want to talk to you unless you are a dealership.

 Posted: Aug 31, 2012 at 10:51 Quote So just say you're calling from a dealership? "hi i'm calling from bikeshop xxxxxxx, a customer is wondering about the shimstack on vivids, blah blah" Not hard to do?

 Posted: Aug 31, 2012 at 11:17 Quote Just got through to Sram, they shims are not interchangeable. Oh well, at least a new shim won't cost a whole lot.
