Cannondaleriders

I'll check the sping in my garrage tonight from when I had the conversion done to mine.

This may be a long shot but we had a 400ex that we found a spring from Mcmaster carr that fit perfect in. It was 20 bucks and made it ride great for a 125 pound rider. Ill see if I can locate the spring if you want to try it. He eventually went with elka shocks soi I know its just laying around in the garage.

Canniboomer has the moto spring and im gonna try it. If i dont like it ill let you know. Thanks wistech.

my extra spring sitting here is 698-36/105 L122

OK...after some more thinking im back to the drawing board. Is a ZPS set-up the way to go on my rear spring or just a softer spring?

I am thinking about doing a few different things:

a. buying a zps spring set and putting them on and trying it.

b. buying a moto spring and trying it.

c. sending the shock to pro pilot and having it set-up with zps.

d. buying the springs and having cannondale27 revalve it.

e. OR finally having 27 revalve and use a moto spring.


Sorry if it seems like im going on and on but i really dont know jack about suspension. What i do know is that my rear shock is hurting my riding ability right now.

Im open to any and all oppinions.

What exactly is happening when you ride that is the problem? Is it too stiff when you hit a bump, is it rebounding too fast and kicking you, those two things can feel the same sometimes. Are you able to bottom it out off of a large jump? Do you hit large jumps? For a woods machine, I don't know if that is much of a concern. What ride height are you at?

It is way too stiff when i hit a bump. I know for a fact the shock im using right now has a problem. Steve (C27) looked at it at the group ride and it is bottoming out before it even hits the rubber bumper. So what i am going to do is change out that shock with a known good one that i have layin around but before i do i want it set-up for my weight and riding style. Havent checked ride height so i cant answer that now but ill take a measurement. Jumping is minimal, but if i do wanna grab some air i dont want to have a problem. Im just looking for a really nice plush set-up for my riding style. I dont know exactly what i need to do to achieve this so thats where im looking for help. I do know that the stock cannibal/speed spring is to heavy for my weight (160-165) so just wondering what direction to go.

If you ZPS the rear you need to do the front.For trail riding although nice its really not necessary.Another issue with ZPS converting the rear Ohlins is our Ohlins is a PDS shock.Position sensitive damping.So in the last two or so inches of shock travel it is designed to get extremely stiff.It does this with a second piston and chamber.Well if you ZPS it you are already into that last few inches before you even hit a bump.There is only one/sometimes two companies doing ZPS conversions who remove the second piston to allow for a plush ride in the end of travel but if doing that you are in effect neutering the shock.Might as well do a fox.That said buying a set of springs and putting them on is a good alternative since the vast majority of converted Ohlins shocks converted by the big companies do not have any internal changes done whatsoever.Valving is exactly the same as stock or 1 shim removed from compression side.Nothing wrong with that.It works.But it is not the same as buying a shock that was originally designed to be ZPS.Heck alot of the conversions by the time it is low enough to be effective its sitting on the Bump Stop.So really what I am saying is if you want ZPS buy a ZPS shock.I cant think of anyone with more experience doing no-link ZPS setups than PEP.Here is a pic of our shock so you know what I mean about the two pistons.[attachment=4761:TCS_Elka..._valving.jpg]

The best rear shock I have ridden on so far has been the dual rate conversion I got from Adam Warren. It is nice and plush, yet resists bottoming very well. The elka I am using right now is very good also, but not as good at resisting bottoming. I could probably up the compression damping some, but I don't want to give away any plushness on the small stuff, its a trade-off you know. I am running mx only though. I sure wouldn't bottom out either one in just woods riding.
C27, I sent you my mx tech converted rear with the fronts Pete should be dropping them off. mx tech forgot to fix that little o-ring we talked about earlier. Wait until you see his dual rate job. It is different from any other I have seen. It looks like he put my original spring back on and added a collar and small spring. Maybe Speed 1B could try it out if he wants. I don't really need it.

I ran my set up in the 6 hour race and it felt great in the woods. I'm sitting here trying to remember anything that I would have wanted different that day as far as suspension goes, and nothing somes to mind.. I always would like a plusher ride, always....When companies are making shocks for mx versus xc, what do they do differently?

They make them plusher for xc.Higher ride hieght also.
