>>1082506>what about the wear on the cogs?Again, negligible.
> there is a huge overlap in the 26-34> there is way less overlap in the 26-40You're exaggerating. There is more overlap because you have an extra cog in the rear. The thing is it doesn't matter because you're not suppose to crosschain (not saying that because it's bad for the drivetrain but because you should be shifting the front before reaching the end of the cassette).
