Speaking of headset, my buddy has been having headset issues for awhile now. Comes loose all the time.
Started chatting with him about it and he says he needs a new star nut, as the one in the forks keeps pulling up.
Told him that doesn't really do anything to keep the stem tight over time, just a set bolt.
Started looking at it, pinched stem and tapered/crushed steerer tube.
Serious fucking injury avoided, dude shreds and I cringe thinking of the million times that could have gone really fucking wrong.
