If your gonna use those CMT pulleys - Read this

[Ed Sparks]

I looked at those neat new CMT shaft to hub collars that CMT donated to the kit and started to play. I failed to read the instructions first (as most of us easily excitable engineers often do)

Big Mistake !

They work verrrrrry gooood at binding the pulley to the shaft. The thing they don't do is release that well or even at all. Don't torque 'em down 'til your sure!

PS

CMT released these prototypes to us. We are literary trying these things before we can buy them. All they are asking for is a little feedback at their forum:
