Actually it means -2.

I ment my +1 as an agreement with Substructure, not as an argument.
I left it vague on purpose because I thought it was funny that it could be interpreted either way .

I also pretend it's SRAM when I shift, as I dream of "making the leap" from my ultegra stuff. My ultegra is reliable and very smooth, but from the small number of samples of SRAM that I have taken I prefer the ergonomics and the mechanics of the shifting.
