MW Industries Carbon Composite Bellows Shock Spring 18

MW Industries Carbon Composite Bellows Shock Spring

No, that's not a neoprene shock protector. It's actually a carbon spring system that reduces shock weight and provides additional tuning options. This creation was one of the biggest highlights from day one inside Interbike.

Known as the CCBS system for short, it's essentially several cone shaped carbon discs (or elements), paired in sets and joined to make a spring stack. The spring rate of the stack is determined by the number of elements, the base rate of each element, and their series or parallel orientation in the stack. Want a slightly stiffer spring? Or perhaps a progressive spring? Want it to ramp up sooner or later? The system can be quickly modified to achieve many spring curves and rates. A lip and flange on each element keeps them centered relative to one another.

MW says that the CCDS stack weighs significantly less than the steel coil alternative. For this short stroke shock the weight savings was just over 0.3-pounds. Hysteresis is also much less with the Bellows system than that of a coil spring, and it eliminates the slight bind/friction that coils are prone to.

The system shown here is made by MW Industries, the second largest spring manufacturer in the USA. It's still in the prototype phase, but the company believes they'll have good testing results based on their success with similar designs in other applications. Cool stuff!

Finally, after seeing the Hyperco carbon bellows springs I've been wondering when they'd be used in any high performance industry. Koenigsegg is just now using them on the first supercar. Air shock weight with coil shock performance. Of course it will be pricy, but everyone can decide what performance level they want to pay for.

I don't think these filling with mud is a big problem, but muddy water will get in between the carbon elements, either during a ride or when washing the bike. I wonder how quiet they will be with a grinding paste of dirt in there. I wouldn't want to remove my shock and remove/clean a stack of 40 or so 'elements' every time i wash my bike.

not sure either, but if i had to take a stab at his assertion, then i'd say that's the day we start adding all things electronic to what was meant to be a purely mechanical+hydraulic system. motors and electronic shifting? seriously? wtf.

Because that happens sooo often? In my experience, the CS/ST yokes and fork crown will fill with mud long before the shock receives enough to make it more than a little dirty. I see what you are saying, but don't see it as a real threat, and if it is, put a boot over it. Bam, non-real problem solved.

Good lord can you imagine all the forum posts on this??? "Which carbon discs should I use?" "I just added 3 more carbon discs to the upper middle on my shock and now it is soooo progressive OMG!" "Something on my shock is making a plastic rattling noise, should I tighten my shock collar?" "What grease should I use on my carbon stack?" "Made my own carbon spring and lacerated my thigh when I bottomed out, Pics!"
