The EZ clutch pull is a quality made piece, I can see why it has a $400 price tag- don't expect to be pulling air, like in some other videos they act like 'OMG this is amazing', there is a big noticeable difference between stock and the R&Duro, I noticed way less muscle fatigue and pump in my forearm and finger(s), without the EZ pull after an hour of hard enduro I go from 1 finger pull to 2 and then 3, with the EZ pull I pretty much use 1 finger for the whole ride occasionally using 2 finger on the real steep hard rocky hill climbs. On the scale the pull on the stock clutch pull was pretty much a steady 13 to 13.5 lbs of pull and when releasing the clutch. The EZ pull fluctuated, the initial pull is approximately 10.5 lbs but drop down drastically to a low of 7 to 6lbs, also when releasing the clutch but keeping in the sweet spot when doing technical stuff is where the EZ pull shines, the pull on my finger is way less when releasing the clutch. Also, it is not waterproof, so its good to take that bottom cap off, clean and re-lube after every couple of washes. if you like the video- hit the like button, subscribe, and hit the notification button.
