Electric shifting yes or steer clear

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

Yeah, that's what I said earlier. The wireless shifters will likely be non-rechargeable due to the low current demand while the derailleurs will be rechargeable from the same cable harness. Not such a big deal.

[In Thurston Howell III voice]Manual labor, how dreadful!

I REALLY can't fathom what must be going on with some people's bikes, when they say things like "I'd never go back to mechanical Ultegra"! I JUST don't get it! We're not talking about some draconian laborious chore being replaced by the pushing of a button; we're talking about a derailer being moved a fraction of an inch by a virtually fool-proof indexed mechanism which receives it's power from one's hand insted of a battery. What exactly is so bad? I had a Sora/2300 triple on my first bike- after having to make a few adjustments over the course of the first few hundred miles, I never had to touch it again, and it never missed a shift or threw a chain.

Tsk. Tsk. How little you know. The garage door opener will actuate the wings for human powered flight. It is the TV remote that will cause a problem.

Very informative thread. I never knew steel cables stretched, and always assumed it was the housing collapsing over time. Who knew?!?

Cables? Cables? We don't need no stinkin' cables.

Good observation. I wonder how consistently negative or positive the attitudes are on the two topics. I for one am split, pro electronic shifting and con disk brakes. Hmmm, sounds like a poll thread.

Cause you can't wait till you laugh at them as someone is hacking their shifting mid ride? Lol, that's the silliest thing I've ever heard.

Only issue with wireless shifting will probably be misshifts or losing signal altogether. Not sure if Shimano will ever go this way, but the cables are there for redundancy.

Huge discussion at slowtwitch on this. Velonews, specialized and November cycles did some aero test with disc brakes. I also think specialized did their own quick basic test with it. Really showing disc brakes are al it's negligible on aero.

The only one of the sources mentioned without a horse in the race is Velonews. They showed a loss of 1-3 watts in most conditions but 8 watts when the wind hitting the disc side of the wheel at 90 degrees. Not a significant amount but not neglible either.

Steel cables do indeed stretch, and housings collapse over time. When you replace an old cable, but reuse the same housing, you will still get cable stretch for the next few hundred miles.

No, the individual strands of metal are not actually getting longer, but the wind of the cable is setting, and the cable is getting longer.

misshifts from radio interference could be a huge problem though. I don't think hacking will become an issue for most, but I wouldn't put anything past the pro teams in the grand tours.

This is how I land on it now. I love the XT disk brakes on my mountain bike, but I don't do that kind of stopping when I am riding on the road so I don't see disk translating well to the type of road riding I do. I just never had a problem stopping a road bike....


but I still use aluminium rims.

I've never had an issue with tires blowing out because of heat either....

but I don't decend mountains quickly either.

Could be, but then that is what SRAM is working out of the system right now, don't you think? I would imagine the shifters and corresponding derailleurs on that same bike will be coded to work exclusively together, and I'm sure there will be other safeguards as well.

I'm sure that's what they are working on, but I don't think they'll get it right.

The delay getting SRAM's offering to the market has be concerned about just those issues too. But it is just a programming problem. Bright folks. How hard could it be? Any company who could develop the Power Dome cassette, can do anything as far as I am concerned.

You really think the Power Dome is that big of an accomplishment???

Okay, so it can be noisy. I don't have problem with that using KMC SL chains. But it is the most elegant solution to reducing cassette weight we have seen yet, eschewing aluminum and titanium and still matching their weight reduction potential. I think it is gorgeous. Plus it doesn't cut into Shimano-compatible aluminum freehub bodies. Pretty special if you ask me. I love outside-the-box solutions.
