Hoping that the more mechanically-inclined riders could help me with a
question.
Was riding the other day when my I started getting a rather harsh
clicking / chatter when climbing in the lowest two or three gears. I
can both feel it in the crankarms and hear it coming from the cassette
and I thought that perhaps the chain was jumping and I needed to
adjust the barrel adjuster. Tried that and it's not working. I can
also feel it when the chain's in the middle of the cassette, but the
problem is at it's worst when I'm climbing and standing and really
pushing on the pedals.
Also, I get a rather intense rumbling / vibration when I'm in the
tallest 2-3 gears. It's not a clicking, but definitely some sort of
major vibration that I don't experience in any other gears and,
basically, I have no idea how to fix it.
I would imagine that both issues are related somehow to either the
chain, cassette, or derailleur, or some sort of combination of all
three.
Of course, any insight lended is always appreciated.
