    Highline sag question

    Mmkay, so if the rear shock has 2.75 inches of stroke (~70mm), and I'm looking for about 30% sag, then I want about 21mm of static sag, right?

    Is 30% the ideal, or am I looking for more/less?

    30 is what the book says, i haven't measured mine exactly but i'd say i'm around the 25% mark. feels plenty good enough for a pie eater like me!

    You can try this calculator http://www.tftunedshox.com/springcalc.htm. That page also talks a little bit about what sag you should have for the type of riding you're doing.

    BTW, when you're checking sag you want to have 65% of your weight on the back tire and 35% on the front. That seems to be the most common standard

    Set at about the suggested sag and then go for a ride. Adjust either way accordingly. Bike rides are more informative than rulers.

    I'd say 30% is ideal. At least in my case it was. First I was running #500 spring/ sag around 25% and rear was bad, really bad. Swap for #400/ sag 30% and now it's fine. It brakes and rides much better.

    Hi Tap, woo.

    Thanks for the info folks. So, am I calculating correctly though? I mean, I'm determining a percentage of 2.75", correct?

    IT: How much do you weigh geared up? I'm running a 400# at Turner's suggestion, and I almost feel like I could go lighter.

    You are correct.

    I've found that with almost every design, especially my turner, I tend to like lower than reccomended spring rates. Your shock has a lot to do with it too. I'd back off the boost valve and propedal so you can start as close to a straight spring as possible. Back off the preload collar as much as you can and see if it works for you then go from there. There's kind of a balancing act between damping resistance and preload you need to play around with.

    Bag: I weight 172lb w/o gear. Full geared I guess 177lb. As I said #500 was too much for me. Now it's fine, bike handles and brakes great.

    Hey Bag,
    I weigh 210 with gear and was recommended a 500.. Felt rough and not very compliant.
    Now I've got a 450 on there and it feels fantastic. Try running a lower spring rate. I run about 30% sag, with a CCDB and its perfect for me. The Highline is truly a kick-a$$ rig once you get set up right.

    I'll echo what hambone said. I'm about 210 with gear too and just switched from a 500 to a 450 and like it better.

    New question here.

    i've got a highline with a fox DHX coil shock - is it possible to change the travel from the 8.5" to 7"? Do you need a different shock?

    Yes.

    You need an 8.5 x 2.5

    yep, that's my xc setup .

    lots of hiliners are running the 8.5, have a look here

    in fact I think DT mentioned going to the 8.5 stock and 8.75 will be an option for the next run of HL's.

    want to buy a 8.5x2.5 dhx air?
