Finally, I have the Nuvinci N360 paired with the Patterson-Metropolis CVT on my 20" folder. It was no easy task doing this in Malaysia, requiring long waits on the postal service for niggling little parts. The biggest difficulty was in getting the chain length correct, which required the use of a "half link" and a chain tensioner. Ride reports to follow. alt="Nuvinci n360" alt="nuvinci n360"
