Hi I let the air out if shock and measured rear wheel travel as I'd seen in 3 reviews that they measured 142-144-145 mm I got 145mm and if u use 20% sag on ya forks on 150 it's less than 160 do u only gain about 7mm ish tbh I'm looking forward to fitting the new damper as I find the compression on the fork to firm (harsh) and the rebound I'm running nearly open or it gets packed down when going fast on multiple hits? Tbh all the tech and measurement is great but the bike is still far better than me and most people unless u r pretty good I'm only doing it for a bit comfort and I'm a bike tart lol
What a longer stroke provide you with us the option to go for a higher percentage sag than on the shorter stroke and still have the same or more stroke available with a more plush ride. You really don't need more than 150mm travel even if you ride really hard.
Damping should be as open as possible without shooting your wheel up into the air so that your fork is ready for the next hit. With low and hi speed compression and damping things get a bit more complex and most riders will never use that and the shock will actually perform quite well.
