I had a 10 speed Centuar medium cage derailleur working perfectly for
one year until a stick got caught in it during a 4 day trail ride and
snapped it completely off at the bolt. The dropout was realigned by
an experienced wrench/framebuilder and a 10 speed 105 derailleur (I
was in the midst of a trip and away from big towns) worked
surprisingly well (adjusted so that the middle of the cassette worked
great and just OK at either end). After the trip I installed a new
Centaur RD but it will not hold onto the 2nd and 3rd largest cogs (it
autoshifts down to the next smallest cog). Cable tension is adjusted
perfectly elsewhere along the cassette and it is not a problem on the
biggest rear cog (it's a 13-29 cassette). Over the past 8 years,
anytime shifting hasn't been perfect in the absence of any obvious
reasons, a new spring and post in the shifter have always done the
trick. Didn't help in this case. Only thing left are cables and the
individual cogs but I can't see what could have changed. Any ideas?
