Could anyone just confirm if I am measuring the preload from the correct points. If so it was previously set at 25mm so no wonder a bit harsh. Cheers Sent from my iPhone using Tapatalk
That is the preload adjuster, but I thought that you should measure the sag to determine where it should be.
Yep, Bob T is right, the preload is determined by the sag measurement which you get by measuring the suspension travel. There's plenty of videos on YouTube which are worth a watch that will help you out. I'm not actually sure what you're measuring in your photo, the amount of adjustment you have left on the preload adjusters? Sent from my iPhone using Tapatalk
Some people quote a sag measurement, others quote the amount that the spring has been compressed by the preload rings. You need to know the natural length of the spring, then you measure the length on the bike with the wheel off the ground and subtract one from the other.
Had mine set up at Mick Gardiner Racing in Barnsley. They're Ohlins specialists. The suspension was all over the place and they have sorted it really well. For what it is worth it looked much more complicated than just turning a few nuts and screws. It involved me sitting on the bike, a deal of pondering and many, many calculations. I was impressed and know for certain that nothing I have read here and elsewhere would really give me the foggiest idea on what I am supposed to be doing or trying to achieve. Oh and it cost £30.
I understand about setting sags etc and when I get a spare moment I'm taking the bike to MCT for them to wave their wand over it. The reason i ask is the manual states between 17-19mm of preload, it doesn't say where they get this measurement from. Is it from the spring or the adjusters? Obviously with a properly set up bike it's irrelevant and the manual has various errors in it (fork preload direction for example), was just curious where they got measurement from?
I wondered where it's measured from too... I can only assume it's from the uncompressed Spring length and then 17-19mm shorter. Sent from my iPhone using Tapatalk
17mm from the top of the first nut to the end of the thread which gives me 5mm of static sag Sent from my iPad using Tapatalk
The owners manual is a joke It's full of things like this. Says to wind rear compression 2.5 turns for comfort setting and it's only got 2 turns adjustment!
I would say from spring to the end of the thread (so 17mm in the first photo) seems to make sense with the numbers in the manual. Mine currently at 19mm, because 17mm felt too soggy even though for my weight (90kg in gear) it gave 20mm sag.
Turns or clicks? Whatever it is, mine has 2.5, because that is what it was set to when I checked it. (959, but I'm sure same shock/manual)
Turns for comp and clicks for rebound on the rear Mine only has 2 turns comp adjustment - I've read a few other forums which say the same too.
Mine definitely had 2.5 dialed in when new because I checked and noted it down. Set to 1.5 now anyway, which feels much better.
You have me wondering about my 959 and wanting to try changing the settings. The book doesn't make sense to me. The more I read the more confused I'm getting
Well worth just winding them back, counting and noting in the book. Minewerenotsetto anything specific from the book, and after playing a bit I'm halfway between Road and Track settings. Nice and firm, but not too bouncy.
