New "aerodynamic" TT shifter from SRAM. Really?

Road Cycling “It is by riding a bicycle that you learn the contours of a country best, since you have to sweat up the hills and coast down them. Thus you remember them as they actually are, while in a motor car only a high hill impresses you, and you have no such accurate remembrance of country you have driven through as you gain by riding a bicycle.” -- Ernest Hemingway

New "aerodynamic" TT shifter from SRAM. Really?

Regular TT shifters have a set position for each gear, which means than they'll be pointing straight up in certain cog positions. Apparently that's not very aerodynamic, so SRAM decided to make one that shifts with a ratchet, meaning they return to the center position each time. Pretty cool if you ask me, but the thing only saves 36 seconds.... over an IRONMAN bike leg! Wow.

Yeah, it's really just a matter of bringing the bar-end shifter into this century. I had called SRAM last year to propose this idea, and they said they'd already prototyped them. Another BFer did as well, independently, so I think this was a pretty logical next step.

The Aero benefit is small, but the ergonomics will be much better.

Surprised it saves that much time. A regular shifter will be pointing up at the extreme end of the cassette gears and not all that long.

But it's not only the shifter, it's your hand position as well.

I think actually it's the Electronic Dura Ace TT shifters that will do that.

Well considering you tend to wrap your fingers around the shifter most of the time, i think that negates the aero benefit....but hey, looks like a cool system (that will probably cost a fortune).

I imagine grip shifters on the aero bars would be more aero.

Yeah, I guess it's more like bringing them into the 90s, when road and mountain bike RTC systems came in.

I like the looks of those, I don't have a TT bike but the functionality seems to make sense.

My first thought as well. Also...this is something that baffled me as soon as I started my TT setup. Once I rode int he setup I was shocked that there hadn't been anything done to improve bar ends in this respect.

Kudos.

I don't see myself "upgrading" from regular bar ends, but at least this will present a decent option for many just setting up a new TT rig.

Ah, now I know why SRAM came out with these! Dang, that is one smooth setup.
