Front derailleur rub & STI(3 posts)

Front derailleur rub & STIMatno
Aug 9, 2002 12:32 PM
I'm just pondering making a switch to STI shifters. I currently have a friction front shifter (DuraAce)and can trim it easily, and I'm wondering whether there is a problem with "indexed" shifting of STI levers that would limit my potential gear combinations. Can anybody help me out with this one? (The reason I want to switch is that I currently have downtube shifters mounted on my aerobars, but I want to be able to remove the aerobars for some rides without having to move the shifters. I don't like having them on the downtube though because it's too far to reach).

The sti fronts have trim positions.Bar end shifters are another possibility.

If you have a double crank set and if your chain line is correct there should be no need for trimming. I have two road bikes with double crank-sets and never have any need to trim the derailleurs, and there is nothing special about either bike. One has STI D-A 9-speed, the other is S 600 6-speed friction down-tube. There's really no indexing on the D-A double front shifter. It does have a some friction type trimming in that you can use the levers to slide the derailleur in as much as 5 mm from either end. I've never used this feature and didn't even know I had it until recently. Trimming should not be an issue with deciding on STI.
