As a confirmed friction-shifter, I am intrigued.

Modern friction shifting
Re: Modern friction shifting
Old idea doing the rounds again. Who recalls those dreadful Modolo Morphos shifters which could be set up for different shift numbers and systems.

Re: Modern friction shifting
They were my introduction to "brifters" back in 1999. I would have been using a six speed freewheel at the time, maybe seven. I recall the indexing worked fine, but the braking was a bit grim (I was using sidepull calipers) which I think was due to the brake cable routing over a circular guide (like the a Sturmey pivot) inside the lever. I think this was a bit too flexible.
About ten years ago a friend tried the more modern type, but I do not know how he got on with them.
Re: Modern friction shifting
I was using those modolo levers in the rain on one occasion when my thumb slipped off one of the gear levers which sprung back and trapped my thumb between the 2 levers. I couldnt free it until stopping and using my other hand to depress the gear lever.

Re: Modern friction shifting
Interesting. Of course, the article is wrong to say that friction shifting is different because it allows you to ride along not correctly in gear. Indexed gears do that too. It's got little to do with how the gear is shifted, and everything to do cables stretching and so on, which happens equally with any cable-dependent system. Probably with electronic ones too if they are wrongly adjusted, but I've never tried one.
What is true is that friction shifting allows you to move the gear infinitesmally, so you can make a right alignment wrong and a wrong one right, merely by moving the lever.

Re: Modern friction shifting
It also says in the article that it can be used for indexing with different ratios (that's how I read it anyway), which could be useful - but at that price how many will buy it? I used to use friction shifting, but with my (albeit budget altus derailleur and 7 speed) the index change is so fluid that I sometimes wonder if it's happened. The old friction shifting was ok to use when the feedback was chink! chink! chink! and it was clearly in need of adjustment, but I think I'd struggle without indexing now I'm used to it.
Re: Modern friction shifting
They look too complicated, over engineered. Same as the adjustable pedals.
Friction shifting from the bar ends or down tubes etc is perfectly fine...cheap simple friction shifters on the drops may have a market. But with the dropper post, multiple indexing. They become too upmarket and competing with high end groupset brifters. Which I don't see them competing with.

Re: Modern friction shifting
The shifters are for the American and Japanese markets,
Rivendell(coming soon), Rene Herse and lots on NOS Suntour friction rear mechs in the USA.
The Japanese make new Cyclo dual cable shifters.
Growtac will sell a few hundred.

Re: Modern friction shifting
can also be achieved if admittedly to a lesser degree with flat bar shifters with extra trimming stops (some triple front shifters have an extra 2 stops) - has helped a few of my bodge builds. also (tho that shifter only has a single extra click) helped my Hewitt - long puzzled by slight issues I had had with that, I learned from here (I think from CJ - trust I am not misquoting) that the commonly fitted front XT mech isn't strictly within spec with the frame/set-up.

Re: Modern friction shifting
Campagnolo Ergos were long loved by tourists because they had a lot of closely-spaced click-stops, rather than three specific ones. This helped with trimming, which was more of an issue on wide touring gears. That, however, was up to about 10 speed. Not sure it applies now.
