Shimano Dura-ace barend shifter question?(7 posts)

Shimano Dura-ace barend shifter question?wilsonc
Aug 21, 2002 11:19 AM
Does anybody have experience with these? i just got a tri bike and want to cut the syntace aerobars down a tiny bit. of course, that involves removing the barend shifters... but i cant figure out how. i have removed the levers, and there seems to be a allen bolt in there, but it doesnt move.
ideas? help?

If I remember correctly, you are dealing with a left hand thread - it will come out. It is an expander bolt, so you could tap the body with a rubber mallet prior to loosening the unit.
Yup, turn the bolt clockwise to loosen (nm)BipedZed

And for cutting the bars I'd consider using a pipe cutter. It makes a straighter edge than a hacksaw. The cheap ($4.95) ones work fine for me, but the blade wears out quick.

... and you'll have to dress the cut a bit to get the barends to fit... an appropriate round or half round file should do.
Reverse threads? whose crazy idea was that and why? (nm)wilsonc

They're only reversed from the end you're looking at.cory

It's a conventional thread, but it goes in from the other end of the shifters, as though you were inside the handlebars. Since you're working from the threaded end rather than the head end (though there's a hole for an allen wrench in it), you have to turn it "backward."
