Hey guys! Just thought I'd post up my version of how to fix the slop in the 17mm wheel hexs. It only took my about 10 min to fix all 4 tires. Really easy, cheap, and VERY effective.
What you need:
Roll of plumbers Teflon Tape
First, after you take the wheel off, take the teflon tape and start wraping it around the threads on the axle shaft. I'm not sure how much is enough, but I just do about 2-3 wraps.
Then, grap the axle shaft and press down hard while turning your fingers with the way it's wraped, so you don't un-wrap it. You need to do that to press in down into the threads and push the air bubbles out.
THen, when you put the wheel hex back on, push it on slowly while turning it, so it "squishes" the teflon tape even with the wheel hex. It will scrape off the exess teflon and push it to the start of the threads. When you done, it should look like this. Notice the "ring" of exess tape where the threads meet the axle shaft.
All that's left is to pull of the "ring" of exess tape off, then put the wheel hex back on! Tada! No more wheel hex sop! I hope this helps you guys as much as doing this helped me!
