Silver2 shifter apparently shift 12 speeds fine, even with SRAM rd

I'm only up to 10, and that with an 8-sp-era road rd and Barcons, but this is heartening news. 

I'm tempted to try my Barcons with a 12-sp road cassette, tho' I'd have to swap out the DA 7401 rd for an 8-sp XT rd, I guess to handle a big-enough granny cog to make it all worthwhile. Actually, I should proceed gently, and simply go to 11 first.

Forgot to mention that, as with mechanical disc brakes that many people complain about, there really is no problem, at least in my not inconsequential experience, shifting 9+ speeds in friction using just about any shifter and rd combination. The Barcons, the 7401 rd, and an 11-sp chain shift 10 close-ratio cogs very, very well, better than any friction 8-speed setup I've used. Interesting; back almost 20 years ago, I had the same experience shifting close ratio Am Classic 10 sp cogs with Simplex retrofriction dt shifters pulling the same rd or its 7400 or 7402 sibling; not just acceptable, but wonderfully. Hell, friction shifting 10 cogs is smoother than any 7-speed Shimano indexed system I used.

I'm using what I believe is a silver 1 shifter (is at least from 2014) with a sram road derailleur and a 1x11 drivetrain. Works like butter.

Hmmmm, gonna have to try this w/ my Shimano 11 speed (11-51).

I guess my reaction to this would be "why would it not work".  It's a friction shift lever.

So long as the limit screws on the rear derailleur are set correctly, and the lever has sufficient travel to sweep the entire distance between the high stop and the low stop when connected to the cable, there's no reason it wouldn't work.

I suppose you could also talk about cable pull ratios and maybe there's a situation under which a friction shift lever didn't have enough travel because of multiplication or division of travel, but it still goes back to the same question, is there enough travel when the thing is connected to a cable, so more or less a yes or no question.

RBW said it won't work; quoting BS quoting Riv: 

These are compatible with up to 9 speed rear derailers only. Not compatible with SRAM rear derailers.

But this recently appeared on the web page:

HOLY COW, FOLKS: These will shift up to 11 speeds when used with a 9/8 speed rear derailer. The latest 10/11/+ rear derailers require more cable to be pulled making them no good but a 9 speed rear derailer will still shift through an 11-speed cassette easily. Match your chain to your cassette, and the 9sp rear derailer works!

In fact, BSNYC is using them to shift 12.

The main complication is indeed lever travel; and this is why I find Suntour Barcons with more "pull per inch" better for 10 cogs than Silver1s, even though this means that shifting takes, theoretically, a bit more care. In practice, the Barcons work fine with 10.

When my Silver1 shifter broke and I replaced it with a Suntour Barcon. I was surprised by how easier it was to shift to the last cog on a 10 speed cassette compared to the Silver1 shifter. My initial set-up with the Silver1 shifter was with a Deore XT 10-speed derailleur. The last cog was almost impossible to shift and sometimes didn't. I replaced the Deore Xt with a Claris 9-speed derailleur and that fixed the problem. However, I had to swing the Silver1 shifter all the way up to get to the last cog. It is now easier with Suntour Barcon. I sometimes wonder why a bicycle company hasn't come out with a modern version of the Suntour Barcon....

Just adding more similar data here...

My Silver1 shifter set up on the Riv bar-end pod shifts a Sram Rival through 11 speeds (11 to 42) with a 33t chainring. It does so very nicely.

Before mounting this shifter (last week), I tried out a Suntour barcon, which could not get up to the last, largest cog.

Anyone trying to do a parts bin friction 1x system, you could try using an old left hand front shifter as the rear shifter. Mine was a front bar end  friction shifter, now on a Paul Thumbie. I run it on the right underside of grip and it shifts my 1x10 micro shift derailer through a 11-50 tooth cassette great. I use 10 speed chain. Probably could have used an old deore 9sp rear derailer and gotten away with not buying a new one.
