I was never fond of the shifter kits... I've built many of them over the years & they do what they're supposed to, but they're very tricky to install correctly & they always seem to need re-adjusting.

The newer style kits with the large U shaped main bracket are a lot easier to install, but they still need constant maintenance... (the kit shown is a old style).



In all my years of building these bikes, I've found that a standard 'single speed' bike is the easiest to build & maintain; & it can still go fast enough to keep up with traffic.

I actually had a shifter kit on my very first racing bike (for the So-Cal races), but I quickly figured out that I could race faster without it.

I'm sure the bearing in the shift kit would have to be replaced. Good find though. Issues I don't like with a single chainring shift kit are the cross chaining and the narrow reduction range.

The triple chainring shift kit I use solves both of those issues. My reduction range is 66.79:1 to 16.25:1. I also use a color-coded one-hand shifting system. The only time a chainring is changed is when in either rear sprockets (3) or (5).
