QuickShift Clutch Pictures
 

This the the Quick Shift Clutch installed on a pilot. The quickshift is part of a CVT system that allows adjustability in the drive system. The clutch is simple in design, and worked well for me. I didn't run it that much, but what I did notice is that it did shift well at lower speeds, but didn't allow for a lot of top-end speed. This was supposed to be "the clutch" to have when racing short course. Due to the design I can see where dirt could be a problem if ridden in extremely dusty or muddy areas.

This clutch was in pretty good shape. The faces appeared to be made of a higher quality aluminum than the power bloc clutches that are more popular on the pilots.
This is the top of the moveable clutch face. The "spider" assembly slips over the 3 ridges around the center of the clutch. The ridges have a fixed taper to assist with the shift rate of the clutch. There is also a spring housed in the center portion of the clutch to control shift rate.
Clutch is made in Canada by quickshift.
This is a closeup of one of the slippers on the spider assembly.
Here is the spider assembly.
Here is a picture of the inside of the spider assembly. The shift rate of the clutch is controlled by 3 things: The helix on the fixed face shaft, the spring weight in the fixed face shaft, and the cam arms in the spider housing. At the end of the cam arms are small washers that help control the engagement speed of the clutch. I didn't run this clutch very long, so really never played around with clutch calibration.
Here is a better picture of the cam arm weights.
 
I have only seen a few of the quick shift clutches. I have tried to find an operating/tuning manual for them but no luck so far. Overall, to me this clutch felt more solid than the power bloc.
