Here is my project bike for the Sick Bike Parts shift kit install. I really like several options available and weighed the Nu Vinci kit against the SBP kit to get more out of a motor and not be so close to destroying it at high revs when I want some speed and just pedal when I want more torque for climbs and starts. I opted for the shift kit because I trust the dérailleurs system to be very highly developed and I understand it and can make it work with used and very available parts.
Just in case you were not sure which bike is a Moab from the final days of Schwinn being a bike shop exclusive company. Now anybody can sell a schwinn, I got one from Target recently.
