Hi guys and girls Hoping someone can point me in the right direction. I measured my rear suspension last night, and to me its sitting incorrectly and requires adjustment, but I will let you be the judge of that. Measured with suspension at full drop 543 mm, with rear wheel on ground at 525 mm and with load ( me and my gear ) at 490 mm. So that gives me about 18 mm of static sag and 53 mm of rider sag, so I figure the suspension is possibly too preloaded ( as I understand it about 5-10 mm of static sag and 30-40 mm of rider sag is about right ). I also note that the adjustment collar is on the tightest of its settings. And also that I am a heavier rider at about 125 kgs ( working on that too, but that's not the point ) Now it appears I need a special crescent shaped spanner to adjust the collar, but what I am curious about is whether I should have to compress the spring a little in order to get the adjustment collar to rotate past its inbuild detents on the ramp, or should I just be able to get the right tool and it should rotate. Also, any advice as to whether the specs I have posted above is correct would be listened to.
