Gwin was running a 500 lbs spring on his Session, that shouldn't be a lot out of the norm for his weight. Weird if he suddenly changed to running a lot less sag.

On my '09 Session I was running a 500lbs spring too. With about 87kg (192 pounds) I got about 30% SAG. Although the new session has another leverage curve, I assume he was running about 20-25% SAG.


I don't know how transferable spring weights are to suspension designs.Im 200 and run a 400 on an M9.i dunno
It's all about the leverage ratio of the bike.



Yesterday I got my new bike. BOS goodies in front and rear. Stoked! I will start with 30% rear and 20% front. Let's see how it goes. Excited!

He was running 400lb on his Yeti. Assuming spring rates are interchangeable between frames is ludicrous. Member since 2003 you should know this!

Here is a link for inquiring minds... Gee, Gwin, and Leov's setups at MSA 2010. Obviously these settings will not translate directly to our consumer tune'd dampers, but sag and rebound can be clone'd for the most part I believe. Udi might be able to better clarify that. Most important thing to remember is they have custom valving front and rear so compression settings will not be able to translate at all.

Well, I pulled the trigger on a Yt Tues LTD, mainly for parts. The plan is to ride the frame and see how I like it. Next winter I will change the frame to either a Wilson or a new Gambler, unless the stock frame is not to my liking.
But the bike looks solid right now. The Idylle rare air and the Stoy rare look and feel amazing so far.
Look out for the 2013 ride thread.

That's awesome! That "limited" edition Tues had an amazing build(Bos, LG1 wheels, Renthal, Formula, etc) for such a cheap price. If I hadn't bought my DHR I would have done the same thing, buy it for parts and if I liked the frame it would just be a little added bonus. Definitely well bought, and according to the reviews its a very capable bike. Lacondeguy seems to be getting on with it just fine haha post a short review after you get some ride time in. would like to hear your initial impression

Thanks mate, I'll do that. The review will come soon, I hope. Well it snowed yesterday about 30cm, so I have to sit it out at the moment
A week ago I was riding our homespot with 15°C.
And now this :think:

Frame/Shock: Tues 2.0/ ccdb
Rear Sag %:24-25%
Shock stroke 3.5"
Frame travel: 208mm
Sag measured with riding gear?: Yes
Sag measured standing/sitting?: Standing
Fork: manitou dorado
Sag: 18-20%
Travel: 200mm
Thoughts: Pretty much spot on with a 250lb spring run about 20 out of 25 clicks low speed compression, 2 turns high speed compression. the bike feels quite responsive and running a firm setup seems to pay off when riding faster.

Lookin forward to hear what you think about it. I'm in the same situation as you but without the snow haha 75f and sunny here two days ago, to low 40's and raining today(which is quite cold for my area especially in march). weather can't decide what it wants to do and makes my allergies bad

Wow.i thought the 450 felt too skippy.I don't think the bike feels right unless its sitting in its sag a bit.
yeah, i didnt think the 450 was stiff enough, felt a little gushy in the corners, bogged down in the rough and didnt snap through or carry as much speed as the 500, better traction but only by a tiny tiny bit... it might have something to do with the rear shock and the settings your running on the frame itself making it act so much differently - i ran it in 9 inch mode, middle progression, middle chainstay and then slacked out the HA to 63, had a ccdb shock on there which was incredibly sensitive - did you run different settings?

What is your riding weight? 20 clicks seems to be far off of the cane-creek recommendation but they recommend more hsc than you are running.

I'm roughly 72kg with riding gear and was recommended to run the 225lb spring which was just too soft for my liking. I was running a 300lb spring for a while just because I had it from my last bike but it was too hard so settled for a 250lb spring, I then started at the stock settings and increased the low speed compression to suit, then after a while on some tracks I felt like the bike was harsh over chatter so decreased the high speed a bit to compensate since I'm running about 25% sag.

Yeah, I run a few turns preload to achieve my setup. So you should be spot on, I found with my 888s the green heavy spring was pretty good ( i had more sag with it than i have now) so that could be worth a shout.

More sag than with the medium-spring? That's weird. I'm okay with the stock spring (I get around 25% sag) maybe I'll try a hard steel spring since the ti-springs are very hard to get.

linear setting,short chain stay ,9",ccdb.I run my fork pretty stiff compared to the rear.I tightened up the spring last week to get about 25% sag and it livened it up a bit,but there was no forgiveness if you weren't on your game.We have a lot if rocks and I've had a lot of hospital bills,so I don't know if its worth it.
I think the m9 is designed to have more of a planted feel to it and I think that's how it rides the best.But,if its Workin for ya,that's all that matters.

but sag and rebound can be clone'd for the most part I believe. Udi might be able to better clarify that. Most important thing to remember is they have custom valving front and rear so compression settings will not be able to translate at all.
Rebound is no different in that it can be re-valved, and I wouldn't be surprised if some of those rebound setups aren't stock (even though they don't explicitly say that). Less sag = higher spring rates = more rebound damping, and the RC4 shocks don't have a *huge* rebound range in consumer-valved guise. I could be wrong on that count, but as a general rule I would suggest not basing suspension tuning decisions on pro-bike clicker settings.

This was interesting though / makes sense:
I was amazed to hear that the average pro runs the same tuning set up for wet or dry conditions - they may back off the High Speed compression a bit initially from race weekend to race weekend for new tracks and then slowly ramp it back up to where it was by race day as they get traveling faster and faster on the tracks. The pros all run stiffer set ups due to the higher speeds in which they are traveling and the need to keep their bikes moving forward as efficiently as possible. But they all said that they have "play" settings for when they are not racing or holding on for dear life.
Frame/Shock: Intense M9. CCDB coil. (Changing to a RC4 with AVY Advantage rebuild soon)
Running the bike at 9.5 travel in the middle progression hole. I'm going to try the RC4 since I've never been completely happy with the CCDB. The bike rides well enough for my taste, but no matter what I do the square edge performance isn't what I think it should be.
Be good to hear your thoughts with the new shock installed, whether it improves.

I tightened up the spring last week to get about 25% sag and it livened it up a bit,but there was no forgiveness if you weren't on your game.
I've found the same thing - if you're at your peak in performance then stiffer / lower sag setups are definitely faster, but they can punish you if you're not riding at ~95%.

If you're you're not racing but eating altitude the whole day for a few days on rough tracks I think everybody is grateful for every small bump compliance he can get out of his suspension. I usually have trouble to make a fist after 1 week pds.

Frame/Shock: Sunday/ Vector air
Rear Sag %: 27%
Shock stroke 3"
Frame travel: 200mm
Sag measured with riding gear?: Yes, mostly
Sag measured standing/sitting?: Standing
Fork: 888rc2x
Sag: 18%
Travel: 200mm
Thoughts: The rear feels too soft, using too much travel in hard cornering. When I turn up the LSC to compensate it just feels dead, loses small bump compliance and feels like its harder to pedal. I feel like I need to add more spring pressure in the rear, but my sag percentage is already pretty low compared to a lot of people in this thread, and Im worried that traction will suffer. Im not fast, I dont race. Is there something else Im missing? Do I need to go back to a coil shock?
