I want a shift kit like you got real bad for my Schwinn build and I will get one before too long, just went and bought a new MIG welder today so I will have to save my pennies back up for the shift kit now.
:Question: have you had a bike without the shift kit and if so would you say that the shift kit is the only way to go if a person can afford one?
I live were there are many hills so I feel that I could benefit from the lower gears and then cruise the flats at a good speed without the very high RPM's in the higher gears.
There is only one way to go - Get a Shift Kit and be done with it.
I live in an area with seriously steep hills and have ordered and installed the optional 30 tooth dished chainwheel sprocket and 9 tooth jackshaft sprocket and also made a custom 9 speed cassette by breaking apart a Shimano 11-34T and a Shimano 12-36T together with a 19tooth individual hyperglide sprocket to give the following sprocket sizes.
I spent a whole day stripping down the cassette and rebuilding it with various sized sprockets till i found a combination that gives a useful spread of speed increase through the large sized gears and a tight set of gears (11-12-13-14) when road speed starts to meet aerodynamic resistance towing my trailer.
