- Dripped a bit of lube between all the spoke intersections
- Removed/reinstalled axle nuts
- Removed/cleaned/lubed SPD pedals
- Pulled/lubed cranks
- Pulled/replaced chainring bolts
- Pulled/lubed bars, stem and steer tube
- Pulled/lubed seatpost
Only thing I haven't done so far is pulled and reinstalled the bottom bracket. But it doesn't seem like it's coming from there, and I cleaned/lubed it thoroughly before installing and tightened it down. I don't know what else to check!
I had a bike where the headset cups would squeak in the frame. Their press fit was just a billionth not tight enough. Drove me nuts because I thought it was the quill stem inside the fork or the quill wedge.
IF that turns out to be your problem you can just line the inside of the head tube with some nail polish. Or you can use the correct stuff ($) to tighten up interference fits.
