Organic clutch vs 6 Puck Solid: In depth

The difference between 6 puck and an organic clutch is simple in text, but complicated in science.

A sprung hub is meant to absorb shock. The half inch of hub travel can turn into 4-inches of tire compliance, and that makes a huge difference. The lower the gear, the larger the compliance.

Shifting speed is all about disk weight. The lighter the disk, the faster the shift. The fastest shift will be achieved with a single un-sprung disk, PERIOD. The best of both worlds is an un-sprung non-marcel organic disk.

6-puck hubs grab faster because they lack what's called a "marcel spring". Organic hubs have a marcel spring. It allows you to push the pedal more, so you can have a certain level of feel when you're parking or taking off.

However, many clutches have a diaphragm spring that acts like the button on a food jar. It takes a certain amount of force to make it pop. That certain amount force will also deflect the diaphragm fingers. You multiply how much travel is required to deflect the marcel and diaphragm by your pedal and slave/master ratio to get your total pedal travel.

Un-sprung 6-pucks are unique because there's no marcel or sprung hub. If the diaphragm spring is really stiff, you end up driving more by feel and less by pedal travel. It's a very intuitive experience if you can feel when your knuckles turn white, rather than how far you've moved your fingers, or foot in this case.

Organic disks have a quirk in their engagement process. When you slip an organic disk, the surface of the disk is forced to go to a high temperature. Since most organic disks are made of a plastic similar to red Loctite, the disk material converts directly to smoke (thermally decomposes) at a low temperature without melting. The additives in the disk are there to keep the flywheel surface clean, as well as transfer heat into the clutch material to some degree, and then into the flywheel.

6-puck material is able to weld itself to the flywheel because it goes from a solid, to a liquid, to a gas, rather than directly from a solid to a gas. There are certain conditions that force this to happen, namely slipping the clutch at high RPM for extended periods of time. This will deposit clutch material to the flywheel and disable your clutch from successfully disengaging.

Which should you get? You're expected to be competent and mature enough to understand what I've told you and as an inexorable and inevitable result, decide what makes you happy in life.
