How can I tell if my left ultegra sti is double or triple?(7 posts)

How can I tell if my left ultegra sti is double or triple?BowWow

When downshifting (big ring to small ring) I get two "little" clicks and one "big" click that really loosens the cable a lot. I have adjusted the cable slack and the hi/lo adjustments on the derailleur to use only the two "little" clicks, but I don't have enough intermediate clicks to really trim out the derailleur rub. Because of the three jumps in downshifting I was wondering if I have a shifter designed for a triple crank?

Thanks for your ideas!

My understanding is that Ultegra levers are all double AND triple compatible, just like Campy levers. I've never liked STI front shifters and triples much for the reasons you state - trimming is somewhere between a PIA and outright impossible.

If it's 9 speed, it's double/ triple. There was no triple version in the 8 speed ultegra/600.
Easy. Hold it up so I can see it.Spoke Wrench

Yup, it's a triple - unless, of course, a double is what you wanted.
OK, It's a triple. So how do you set yours up?BowWow

Do you set it so the cable is slack in the small ring, or adjust it to use the middle click to go to the small ring, and the third click for the big ring? This is how mine is now (middle, third)...

Thanks again for the help here!

This is probably one of the more touchy adjustments to make on a bicycle.

I set mine up so the cable, when on the grannie, is just taut. If you get it right, it will give you two shifter positions for the middle ring and one shifter position each for the big ring and the grannie.
Thanks! This makes perfect sense - I'm right on it! nmBowWow
