  • "If the cost of adding machinery to go up isn't already too much, why not just have a descending system that takes no work? Get in at the top, release the stop, glide slowly to the bottom. Otherwise, valuable for space savings alone!"

  • "A couple fun technical points:A lot of the "assist" bikes just detect when you're trying to put out power, and then they assist. The button only turns on/off that functionality, so it could be left on for a whole race.Many bikes these days have "electrical cables" in the seat tube. Mine does. The battery for electronic shifting (now common on bikes above $4k) is often housed in the seat post, so that's not a surprise.Second hand, I've heard the method to check bikes is by looking for an internal heat signature. Solenoid driven shifting wouldn't be inside the frame or be a large heat source compared to a motor, so using a IR camera might do the trick.Also, for those not in the sport, 100 watts sustained assistance for a 135 lb world class (Tour de France) rider is basically a 25% power boost.This will be the first of many!"

  • "These are photos from my work. We have 4 of these tool chests, each in a primary color (red, yellow, green, this one is blue) so you can't mix and match from different chests. Every tool, including sockets, were milled/lathed to create reliefs and painted the color of the chest. The organizers are sheets of acrylic with colored surfaces to match. The layout for sockets lets you test bolt sizes, but groups them pretty clearly by drive type and length. It takes longer to open the drawer than find the right tool in these, but I think they are prohibitively expensive and time consuming to make for home."
