This what happens when we have too much free time. It's a Grand Cru 50.4bcd crank set up with four chainrings. In this case it's a twin half-step. This may have possibilities, instead of running a 1x5 on your city bike, you could run a 4x1. Or how about a 4x11--so many gears? Boggles the mind.
In other news: We have the Maryland made Grand Cru handlebar bags in stock again. The first production run sold out fast.
We also have these cool stickers. You'll get one free with every order, and you can order extras.
