thousands of shifts and 3 months of standby battery life for my non-destructive electronic shifter. If you love your vintage rig but want to add some precision (or just a bit of fun), keep on reading.

These 3d printed bar end shifters are a novel solution for changing the way you shift gears.

A cyclist can easily modify the CAD files to suit *any* derailleur that is 10 speeds and under…just by changing the values in a text file. Pretty cool if you ask me.

What started as a basic tune-up turned into a full-blown overhaul. Subsequently, after building three bikes I’m here to tell some stories about some parts I’ve designed along the way. This post is the background story and the color-commentary to the DIY design work. In other words, the engineering will follow and, for those eager to see the designs, you can skip this content without missing much.
