on derailleurs and cogsets
so here is the deal with rear derailleurs and cogsets
the top pully of the rear derailleur is supposed to be adjusted so
that it is riding close to the cogset
the best way to do this is to shift the rear into the smallest cog
and maybe the middle ring up front
there is a small adjustment screw on the rear derailleur at the rear
that is...the spot where the derailleur actually bolts to the frame
that little screw makes the adjustment.
so if the top pulley of the rear derailleur is too far away from the
there may be issues in shifting performance.
i'd be hard pressed to say that every bike out there is properly
and they all seem to shift just fine.
