Pure genius. Building the wheels for a new bike? Do this.
Downside – if you only have a built bike, it’s more trouble to remove the fork and stem than not.
I’m really digging on the “these things I had laying around worked together in perfect concert to do what I needed” vibe. V-brakes, gear cable, and a jag-wire barrel adjuster, and the ‘feelers’ are probably better than the truing stand I’ve been using for the last couple years. Serendipitous.
