what does this complicated machinery do then?
It makes the shock bottom out about 12mm before it should effectively giving me 8.0" of travel instead of 9.1" as I don't need 9.1" of travel for anything near me.
And the CCDB just happens to be the perfect shock to do so on.

Yes. Effectively giving me 8.0" of travel instead of 9.1"

Same geometry, less travel. The geometry is freakin spot-on on the M6, I just wanted less travel and that's what you're seeing. In the future, may even end up running a -1 degree reducer headset so I can get the HA to 65.5 (I like a lil bit steeper angles)
lol very interesting... so your not using the full stroke of the shock so you dont get the proper ramp up values you should be getting. and since the stroke is smaller you probably have to play with compression settings so it actually ramps up properly yet the shock isn't performing to its fullest. pretty interesting indeed.
Who said it isn't performing to its fullest? Say he wants a more linear 8inches. Performance is all personal preference.
Nice thought but stupid at the same time because it's a CCDB and if you knew how CCDB'z work you would know how retarded your statement is.

Read up before you think you know what you're talking about.

exactly. you can adjust your ramp up values and bottom out resistance so you wouldn't need to shorten the stroke. since you would technically bee doing it anyway using the adjustments just like i said....
Dude, you did NOT read the link I posted. Shock is NOT position sensitive, get over it. You're not getting anywhere.
nothing wrong its just that bike was designed to run only 9.5in travel in the rear so it wont handle to its potential in the last inch or two of travel
First of all it's 9.1" of travel and secondly it will preform EXACTLY the same I'll just have less chain growth to worry about and my bashgaurd won't be knickin stuff on the daily.
whatever i just dont see the reason for having a bike like that and then limiting the travel but your choice =/
A slightly more elegant way would've been to re-valve it and firm the last inch of stroke up [a lot]. But really, who cares? I like your style--throw some spacers on it and go shred.
That would be completely pointless and stupid compared to rubber spacers... When I want 9.1" again I just pop them off, no re-valving of a shock you can't open up in the first place.
or you could just adjust your bottom out resistance a lot so u use less travel. and crank up your compression so the stroke ramps up faster.
no your bottom out resistance is the amount of force it takes for the final ramp up of the shock at the end of the stroke.. what bottom out resistance does is create a smaller value chamber so when you get to your end stroke the pressure ramps up faster making the shock harden up much faster... so yes in fact the ramp up would be changed using your bottom out resistance thus leaving you use less stroke... like yeah at times u may in fact use maybe a little more then 8 inches of travel. although it would ride more like as if the stroke was shorter compared to adding bumbers and not getting those final ramp up values intended.
High Speed Compression Damping (HSC): This adjustment controls the compression of the shock for large, sudden impacts. Ex.) G-outs or a large drop. If the shock feels like it’s too easy to bottom out, then you increase the high speed compression to stiffen up the ending stroke. On the contrary, if you’re riding a trail where you feel like you aren’t using all your shock’s travel, decrease this adjustment to receive more travel—very simple.
simply read the last part. if u set it up the opposite way, you can use less travel

this is exactly what i was saying...

Dude, honestly, why the f*ck are you still trying to argue with me?
The Double Barrel isn't position sensitive, it reacts to each hit independently and the 4 adjustable valves control the flow of oil through the shock... The oil is routed back to the bottom of the piston, not like a poopy shock you're thinking of. Now quiet down.
Cheers

im just stating the truth, why do you think your are the first and probably only person to do this? theirs a dam good reason lol and it has nothing to do with being intuitive
so since theirs someone out their as bright as you you feel that it makes sence?... i guess if that's what makes u feel good. enjoy. all i know is im a second year engineering student studying in mechanical engineering and ive been taking some fluid dynamic courses and im pretty sure i know what im talking about. theirs a clear reason why shocks are valved to their stroke and thats why few ppl choose to do what you have decided to do with your shock.
ill just agree to disagree.

Cool story bro. I'm doing mechanical engineering as well in a UC so don't think you're the shit for some courses that have VERY LITTLE to do with this. The concept CLEARLY went WAY THE HELL OVER YOUR HEAD, but that's fine.
Believe what you want, I'll run what I want.
Believe what you want, I'll run what I want.
i dont think im the shit what so ever. but i think i have a pretty good idea of what im talking about. also your profile says your 18 years old, so your not in second year, meaning u probably haven't taken fluid dynamics since in engineering first year is a very general year. so you have no clue what materials are taught within that class in other words what u just stated saying fluid dynamics has very little to do with this concept is wrong.. this is fluid dynamics at its best these concepts are covered more then briefly.
Dude, I know what fluid dynamics are about. I don't have to take a course to have a damn solid idea of the concepts... I use the internet for that crap.
You just don't understand how the CCDB itself functions.

Wow! Those comments from summit800 are getting annoying. This guy really don't know how the ccdb works. Good job on your mod.
I guess Specialized don't know what they are doing with the travel reducer on the demo 7

Summit, you need to chill out and read up. Your definition of high speed compression damping was about as backwards as, well, I don't know what.
Personally I think that reducing the travel on your frame like this was a pretty stupid thing to do, but hey, it's your bike not mine. IMO if you wanted an 8" travel bike, you should have gotten an 8" travel DH bike not a 9.1 and reduced the travel. I think it is safe to say most people think this has a much larger negative effect on the performance than it actually does though; you retain the same small bump compliance as you would with the full 9.1", it is just the bigger hits and compressions in the ground, or whoops if you will. Without changing the spring you haven't done anything to how the bike rides, and if you aren't hitting big enough stuff to go through the full 9.1" of travel, then all those little spacers are doing is adding weight and looking haggard.
That's my two cents.

Why don't you leave the shock set up as it is now, but take off the spacers? If you ever actually need the little extra stroke, it'll be there, but until then, it'll ride the same...
I guess it doesn't matter. It's a cool idea, anyhow.Post A New Comment
