My Shimano setup only hops one cog per click towards higher gears
(smaller cogs) which is ok. Only two per upshift and that's often not
enough. On my old road bike I can go from one extreme on the cassette to
the other in less than 2sec while simultaneously shifting the front.
Both with one hand.

And where you have to remove one hand from the handlebar in order to make ANY shift. Most people who ride with an regularity can shift across an entire 11 speed cassette whether road or mtb in less than two seconds.


And we've been through this with Joerg before. If DT friction shifting were superior, then every pro would use them -- regardless of sponsor driven component choices.


Hmm. By the same logic, if fenders were superior to no fenders, then
every pro racer would use them; therefore nobody should use fenders.

That logic works only if your riding style and motivation is similar to
a pro racer. Mine is way, way different, so my equipment choices are way
different.

The only time I wish I could shift faster to a lower gear/bigger cog on a road bike is when I start in my big ring and small cog because I just changed a flat. The obvious solution is to put the bike into a reasonable gear before getting on it. Moreover, I would be (and was) no better off with friction shifters -- which often performed poorly under load. Trying to shift the whole cassette or freewheel while applying a lot of torque was a recipe for putting the chain into the spokes.


I suspect that the poor performance of friction shifters under load has
very little to do with the shifters. I suspect it's an effect of the
(then) primitive cog tooth shapes, and less refined derailleur design.
IOW I think if you buckle a friction shifter onto an otherwise modern
drivetrain, shifting under load would be no problem.

My folding bike (well, one of them) has Shimano 9 speed and bar end
index shifters that can be set to friction mode. I sometimes have to do
that for a while because (I assume) the folding and unfolding unsettles
the cables. I find it shifts very well in friction mode.

I also dumped friction shifters when Shimano introduced 7 speed SIS. I still had DT shifters, but you didn't have to fiddle for a gear in a narrower spaced cassette. You just clicked into it like a Fisher-Price toy. You would have to have pretty well calibrated fingers to friction shift between narrow-spaced 11 speed cassette cogs...


I don't know about 11, but it's no problem at all with 9 cogs.
