Why do some have their handle bars up in the charge position while others have them down, Personnel preference.
I now have YSS, Works Performance, KYB and Ohlins shocks to choose from and test on one bike.
This does not make me an expert, but at least it allows me to talk about such things with some experience.
I have also spoken to three Ex pro racers about springs and they agree with my findings.
For a progressive spring to work properly it needs to be the length of a fork spring. Short progressive springs are too soft, which is fine if you have the valving heavy. Sure you can get stiffer progressive springs that will work but I have found that if you take a progressive spring and a linear spring with the same start up rate the progressive spring will sag more.
That said I am talking about a shock with only 100mm of travel, so having a slight less tension can make a big difference.
On a modern bike with 300mm of wheel travel no biggy.
Before all rip into me this is my findings after using 4 different shocks on the same bike, so don't be to quick to throw the first stone.
