Bike Spoke protector / dork disc / bicycle spoke guard / bike spoke cover

thingiverse

My old spoke guard (aka dork disc or dork disk, though I dislike that name) cracked after years of use, so I decided to try to print my own. You don't absolutely need one, but I've gotten my chain caught between the cassette and spokes (once ever) enough to prefer one. The nice thing about this spoke protector is that it prints in 2 halves so that you don't need to remove your bike's cassette to install it. It's still a little tricky to fit the guard behind the cassette though. You will need to print 2 of the included STL. Two small 2.5mm wide zip ties hold the halves together. There are additional holes for attaching to spokes, but I don't recommend it, as that will warp the spoke guard and might cause rubbing when coasting. To install, I recommend loosely attaching 1 zip tie to connect the two halves. Slide the bike spoke guard behind the cassette and make sure the tabs engage with the flange of your bicycle's rear hub. When you've got it seated well, then feed another zip tie in to finish connecting the two halves of the spoke protector. This part is a little annoying, but I guess it's less annoying than taking the entire cassette off. Tighten the zip ties and cut off the excess. Not sure if this works well for mountain road or kids bikes - I just measured the old spoke guard and made this one to similar dimensions. Inner hole diameter is 61mm but it is designed for about a 54mm hub flange. The tabs extend to 51.5mm, so a hub flange somewhere in between 52.5-54mm would probably be ok. Outside diameter is 155mm. You will need to print with supports. I think I used 50% gyroid infill with 3 walls. ***This is a work in progress*** My chain rubs a bit when my bike is on the lowest gear, but this works better than what I had before.
