For those who like to try different clutch combinations like me I really recommend the RMV speed 2.5 clutch system..All 3 shoes and springs assembled on a backplate that is also the clutch/flywheel nut so I have several set up..3 carbon with 1.0mm springs, 3 alloy with 1.1mm springs,and also 2 alloy 1 carbon with 1.1x2 and 1.0 x1 etc..to swop clutch just remove the bell unscrew entire plate and screw on another..2 minute clutch changes..

I've been using this system for 2 years now and am very happy with them..
