Question: is the XTR front shifter supposed to have two detents in the big chainring position?
I was playing with a couple older rapidfire+ front shifters i have lying around, and old LX circa '92 and an XTR model of a similar vintage. While essentially identical in internal construction, materials, etc., there was one difference that confused me. The XTR model has a double detent for the big chainring position, while the LX does not. You have to pull the finger lever twice to shift from the big ring to the middle ring. Since i bought the XTR used, i assumed this was some worn out shifter phenomena, but it is pretty obvious from looking at it that the detent is intended to be there. Is this just for front der. trim, or something like that?
All that said, these are pretty wacky little mechanisms. I pulled apart the LX shifter and put it back together within 1/2 an hour. Fiddle, but certainly not any black magic. Pretty cool, actually - just amazing they don't break more often for as many bits are in there.
p.s. love the forum... great stuff in here!
