First Fixed Gear Bike Build Finished

Just finished my first build and I’m excited to bike to work tomorrow using my fixed gear. I’ve been a bike commuter for over 2 years and have been waiting for the perfect moment to switch from a 10 speed to a fixed. Well, someone ditched beaten up bike behind my work with a flip flop hub and that was the day I knew I was going to fix it up for use.

Here are the parts I was able to reuse:
– Brake assembly & lever
– Handlebar stem
– Seat post
– Rims
– Cog
– Bottom bracket and chainset
– Back tire and tube

Obviously as I ride it, I’ll find parts I want to change/update. But I know y’all here have done numerous builds and tweaks, and I’m curious what y’all typically like to update first.
