How freely should this link move?

On the Mongoose Freedrive system, how freely should this link bar move? When compressing the rear shock, should you see both sides moving easily? Would it be a very loose movement (insert joke here, Yeehaa! :wink: ) Or, is it only gradual?

When I compress the rear shock the the BB pivot does rotate slightly more than the other one, but both are slight, and it's not obvious the two points have articulation until you look closely.

I hope this makes sense.

    My guess is thats the sort of link that only has to move very little to achieve its desired effect upon the suspension.

    Thanks, I'm new to this FS game, and I'm trying to get used to what should happen, and what shouldn't.

    It's just that the last couple of rides the rear suspension has felt a little stiffer than usual, so I'm not sure if I have it set correctly. I've messed around with air pressures and I think I previously had it set perfect, but now I reckon I've messed it up.

    When setting the rear sag, should you actually sit on the bike, or should you stand in the 'attack' postion? Obviously, you get two diferent results by sitting and by being in the 'attack' position, but I've seen vidoes on the 'net showing both ways.

    Am I correct in thinking you should be in the 'attack' position, rather than having your full weight on the saddle when setting the sag?

    You need to be fully kitted as per usual riding gear and bag + contents. Stand on the bike in attack position but be careful not to bounce or upset how far the indicator will go. This is because you'll be doing most of your riding standing up so thats how you want it to feel set to.

    Also the shock will have bedded in and freed up making it feel softer, so you may have overcompensated for that when messing with the pressures after. Just keep at it till you get it right and make a note of what pressure you rode with and how it felt. It'll help decide on the best balance.

    As for that link, it's clearly one that doesn't move much, and is also in line of fire for mud and water, so i'd be taking that apart to clean and grease it every 6 month or so to keep it from seizing. The small movement makes it so much easier to jam up.

    I usually set 25% sag sat on the bike, then if it feels too soft when i'm out I add 5psi the next time or take 5 away if its too hard :)

    Cheers.

    I reckon when I initially set the rear shock it was more luck than judgement, so I'll continue to play and see if I can get back to that setting. I should never have messed around with it after I'd got it set right. It was originally at approx. 80psi, but since I've gone back to that setting it doesn't feel the same.

    Maybe I just need to play around with it a bit more.
