Should you be able to use every gear combo?
Say on a tiagra 9 speed with a triple up front. Should you be able to get in every gear without rubbing or the chain skipping a little? I dont mean if it is smart to use some of these combos but on a properly adjusted bike will the big/big and small/small combos cause any problem?
Just curious. Thanks

No chain rub on a triple? The Holy Grail of adjustments. They can't make it happen with a Dura-Ace double...

You might be able to use all of the gears with some trimming. There isn't much practical use, as the big-big and small-small rations are probably replicated by other gear combinations.
Apparently, Campy shifters allow more fine-grained adjustment of the FD, so this is possible.

To use all the gears silently, you need a Campagnolo group.

I can get big-big, small-small on my 105 using a triple shifter on a double crank.
