I had a mid '00s xt derailleur on the old snake bike. Shifting has been suffering lately and I think it was related to the pivot where it screws into the hanger becoming gummed up over of many difficult years of service. Unfortunately, I can't figure out how to get in there to clean it.
So, I had the brilliant idea to replace it with a contemporary xt derailleur with a clutch and all that stuff. I had heard that old thumb shifters (like my deer head xt) don't pull enough cable for 12 speed. I assumed that meant 12 speeds, not 12 speed derailleurs overall.
Well, they don't work. The shifter only pulled enough cable to move about five gears out of seven. So much more for crispness and fewer dropped chains (a pretty rare occurrence). I guess I'll put a '90s stx on there.
That's this week's tech corner with Brendan!
