Whoops I did it again...

It might be that this functionality has changed though - it's been some time.

It's been 12 years

Premium Shimano shifters (such as I have installed on my Vado, Vado SL and had it on my Giant Trance E+) also allow upshifting by pulling or pushing the lever -- these are double action ones!

It is funny to read SRAM explanations related to their own solutions:

• Shimano, Magura, Tektro/TRP hydraulic disk brakes all use mineral oil. SRAM uses hygroscopic & corrosive glycol. And their have a marketing explanation for that!
• Shimano uses multiple gear downshifting with a single click; and they have double-action upshifting. SRAM offers single gear shifting. And of course they have a marketing explanation for that!

Uhm, Stefan, virtually all Sram MTB shifters will downshift three at a time. They use brake fluid for their brakes--because it works well for the application (imagine that?). Many fatbikers won't use Shimano brakes for that reason--the performance can degrade significantly in severely cold weather.

I could be wrong Jon. How comes they call their shifters "Single-Click"?

Well glycol absorbs water and it makes the SRAM brakes less reliable. Low temps? To what lowest temperature would you ride an e-bike? (My lowest temperature ride on a Shimano-brake e-bike was -14 C).

Probably to differentiate those particular shifters from all their muli-click shifters. Their entire Eagle MTB line--I've got about a 1/2 dozen at various price points and they're all multi.

The only MTB shifter I can think of that's single is the EX1 (which I'm coincidentally about to give a try)--maybe that's the one you're thinking about? While specifically designed for eMTB's, it's kind of a moot point as virtually nobody uses it anymore. Despite having some good features on paper, it never really seemed to catch on. I guess the high-end EMTB crowd with 250W motors still felt the need for 12 gears. I'm actually a bit worried the single downshift limitation will bother me as I'm always mashing a bunch of gears down at a time on my 12 speeds. But with only 8 speeds and larger jumps between gears (as well as good downshifting under load) it might be OK. I'll need to put some miles on it and find out. But anyway, I'm trying the EX1 for other reasons.

That's all with respect to their MTB stuff. I know nothing about their road stuff.

Well, the brakes on cars seem to usually work OK. They sort of have to. If the correlation you suggest existed, it would be a big problem indeed. It becomes a big problem on racecars where extreme temps are the norm--if there's water in the system, it'll boil and give a spongy pedal. That's why regularly flushing/changing the fluid was a normal part of maintenance on my Camaro. But I've never "glowed the rotors" on a bike....

Low temps? To what lowest temperature would you ride an e-bike? (My lowest temperature ride on a Shimano-brake e-bike was -14 C).

Well, I just got mine a couple of months ago, but at some point in the next couple of years I'll find myself doing it much colder than that. Fat biking in the snow is fantastic fun, but it really sucks when it's above freezing. It's a cold weather activity. Don't get me wrong, some people do OK with Shimano brakes in extreme cold, but a lot of people don't. A comment just posted yesterday on a fatbike forum that I thought was timely--he was testing a new setup in -12 F:

Forgot how bad shimano brakes suck in the cold. Luckily I have my previous take-off orange Hopes to install, but I got all I could take on this ride from the Shimanos.

Ah, OK Jon! Thank you for your contribution: It has made many things clear for me.

@Jon A:

How sad the new Specialized e-bikes are equipped with the Single Click How lucky I am to own e-bikes equipped with triple or double click Shimano shifters As I told you, the SRAM marketing department is doing their best, same with the glycol based brake fluid

Don't get cross at me though

Crikey, probably my last ride of the year and I over cooked a tight corner that I have traversed hundreds of times. I wound up on my back on a nice soft patch of grass with the bike more or less on top of me. I traverse the street counter clockwise. The only damage was to my pride because my err was witnessed by several people who dashed over to check on me. I regained a tiny bit of face when I used the walk along button and the tilted kickstand to down shift to a lower gear, the mishap was at the botton of a hill. The onlookers thought that was a cool move.

Glad you weren’t hurt with your minor crash. And you were able to regain your “coolness” afterwards. Stay safe out there.
