I've got some Nitto RB-021 bars paired with a Nitto Pearl stem.
It recently started squeaking, and I can't figure it out. I took it all apart and greased everything.
I think the squeaking is comming from the sleeve/bar interface. Is this normal for sleeved bars to creak a bit? It's not a bunch, and it's only when I'm really cranking on the bars to get up a hill fast or sprinting.
