Something to Add
Add to clutch compunds
Organic material as it become hotter has less grip while carbon actually grips better under heat. a Night as at the drag strip will teach you this.
Add to stages of clutches
Rating of clutches, most manufacturers rate their clutches to the point of slip, instead of being able to sustain long term use at specified ratings. Torque ratings are based off of the average torque per crank roation, if you buy a clutch which is border line with the amount of torque you put out, chances are its going to start slipping sooner than later.
Notes for when considering the purchase of a carbon clutch. Make sure that what you are buying is a Full Carbon on Carbon assembly and not carbon on metal. carbon on metal tends to slip quickly and not last as long, especially under high temp. This causes more frequent replacement. carbon clutchs can NOT be fully rebuilt. There are replacment parts for carbon on metal clutches but a true carbon on carbon can only be "refreshed" to some extent
