Ultegra 2-speed vs. 3-speed front shifter. Different? -->(7 posts)

Ultegra 2-speed vs. 3-speed front shifter. Different? -->TheSandman
Aug 18, 2002 12:04 AM
While riding my bike (two chainrings), I noticed that my Ultegra front shifter seems to have three indexed positions. That is, when in the large chainring, one click will bring the derailleur cage to the inner ring. After that, another click will simply loosen tension on the shifting cable, making it very loose against my downtube. After trying to adjust it, I somehow screwed it up so that now it takes two downshifts to get to the inner ring. Did the online retailer send me a triple shifter, or is the double shifter supposed to have this extra indexed spot?

maybe take it to LBS to double check, but the "2 speed" ultegra has an extra little "click" to make tiny adjustment to the front derailleur to prevent chain rub while you are in your little ring (39) up front. if you are truly getting a whole extra shift, you may have the "3 speed" shifter.
Same part number works for double and triple (nm)Spoke Wrench

You or LBS needs to adjust it correctly.

it's the same shifter, with 3 positions for double and triple. On double set up you used first 2, 3rd is locked out by front derailleur "high" adjustment screw. In your case it is adjusted to use 2nd and 3rd.

To adjust properly shift to small ring (with that extra click/loose cable) then take the slack away by rotating adjustment barrel near the shifter. If it isn't enough you'd need to shorten cable at front derailleur good luck
OK, here's what to do.Spoke Wrench

1. Shift the rear derailleur onto the biggest cog.
2. Disconnect the front shift cable IMPORTANT.
3. Make sure the front derailleur is properly positioned on the seat tube.
4. Adjust the low gear limit screw. The front derailleur cage should just miss the chain by a millimeter or so.
5. Shift your front shifter into it's lowest gear position.
6. Pull the front derailleur cable so that it's medium tight and tighten the anchor bolt.
7. Check to see how it shifts.

Guess what? If you've done it right you have FOUR shift positions, two on each chainring. Now you can trim your front derailleur so that it doesn't rub as you shift across the block in back. As a triple it has one for the granny, two for the middle chainring and one for the big ring.
