My Canyon Endurace came with a NDS 4iiii PM. I really liked it, it seemed accurate and I enjoyed using it. Unfortunately the crankarm was damaged and there is no way to take the PM off the old crankarm and put it on another so I was pretty much out of luck unless I wanted to buy one outright. I've put about 700 miles on without a PM and I don't miss it. One day I'll probably buy one of their 2 sided units but for now I'll just ride without a PM.
