3D Printed Road Bike Shifters - Usage Demo
Channel: Joybu
Date: 2019-01-11

After returning a faulty pair of brifters, I set out to design my own drop bar shifters for my road bike, very cheap drop bar shifters. It replaced a pair of A050 shifters that would annoyingly hit my knees any time I got out of the saddle. I've been using these successfully in the latest revision for hundreds of miles and counting. If you have M3 nuts and bolts, headset bearing balls from a junked bike, some ballpoint pen springs, zip ties, and a 3D printer, of course, it's only a few dollars worth of ABS plastic.
Shifting to bigger cogs/chainrings is still a bit awkward, a longer lever might alleviate this and I might upload a revision with one in the future...
