    road shifter question again

    I'm considering the Sora shifters because I already have an 8 speed drivetrain and don't want to go to 9 just yet if I can help it.

    Will a 3x8 front shifter work on an existing older 2x8 dura ace crankset?

    Thanks

    Probably, I think the 3x8 just has extra throw to handle the 3rd ring, that's why a 3x crank needs a wider bb than 2x.

    Does that mean that I'll be able to trim out the throw to the small chainring so that it doesn't have the extra click? I dont want to risk throwing the chain to the inside.

    thanks Bear

    You probably can trim out the lever throw, but you can set the inner stop-screw to prevent the d from moving too far, next to best.

    FWIW I'm using a triple sti on my ride with a double ring and it doesn't bother me. I mean really, having too much slack at one point? No big deal.

    Running 2x9 on one of the mountain bikes, i adjusted the limit screws on the derailluer to the point right before it allowed the shifter to click. No problems with it.

    I've heard there exists a better Shimano road shifter for 8 speed then Sora - it's in the Shimano catalog and assigned a number, not a groupo name....I'll try to get more info today
