The rear shifting in my bike has always been very abrupt, to the point there is a twang that reverberates through the (titanium) frame every time I upshift to a smaller rear cog. From viewing/reading tutorials, I understand the jockey wheels in the rear derailleur should typically line up with whatever rear cog is selected.
On my bike, the rear derailleur seems a bit skewed. Not sure if this is causing the abrupt shifting or whether it is an issue at all. Would appreciate any input. For what it is worth, the rear derailleur shifts through all the gears up and down, its just not very smooth on the upshifts.
