I'm trying to decide if a friend's right (rear derailleur) STI lever
is shot. It will upshift fine- pushing the outer lever toward the
center. Downshifting- clicking the inner lever- is only possible when
holding the outer lever still and pushing at a slightly different
angle. This makes it a two-handed operation, obviously not acceptable.
The bike had taken a fall- slow speed slip on wet railroad tracks- and
come down on the right side. I don't see any obvious signs of impact
or scraping on the levers. He says that it wouldn't shift afterwards
and he walked it home. I put this down the rear derailleur and chain
being grossly offset- 2 or 3 cog difference between derailleur
position and chain position, and I don't remember which way.
I've tried flushing the unit with solvent but that hasn't made a
difference. Comparing the left and right lever motions, it feels as if
the right inner lever is moving at a different angle than the left
inner lever, and this motion is more forward and hanging up on the
outer lever body.
Flush it all again? Try bending the inner lever? Time to get a
replacement? Any experiences appreciated as I have almost no
experience with brifters, and times like this remind me why.
