Every now and then, there’s an ad in a magazine worth following up. I saw an ad for these Capricorn Cyclo Works custom wheels and right away I could see these were not your every day custom motorcycle wheel, there’s so many of those nothing seems to stand out anymore, but these are different.
The wheel in the photo is called Involution and it looks like you just opened the back of a wind up clock or some other neat mechanical gizmo. The best part is that all of those gears turn when the wheel moves making for a rather interesting visual effect. On a practical level, it isn’t. But if you like interesting mechanical design, this is cool. They make a few other designs like the Interference and the Iris and videos on their site show them in action.
Again, not practical, but kinda neat.
