Campagnolo had a prototype of it's electronic shifting system. The problem however is that they have chosen to use the solenoid as the primary driving mechanism. The same goes for Shimano as well. Mavic's Mektronic used the dérailleur pulley to drive a worm gear thus saving weight. Both Shimano and Campagnlo's shifting system requires a very large battery.
The really big issue is if these shifting systems will withstand a immersion test. This requirement seems a bit extreme, but there are occasions when I am riding and you have go through a very deep puddle with no other way to go around.

interesting.
The Mavic system was handicapped by the mechanism. All it takes is a strong jolt and the clutches lift and the bike shifts somewhere on it's own.
The other methods probably use stepping motors with leadscrews to give very precise and reliable position sensitive shifting. The problem is that they use quite a bit of power.
I'm still trying to figure out what the advantages are to electric shifting. Anyone got any suggestions? True that if you have electronic shifting you can shift even if you're a weak kneed shifty eyed moron - say like Kyle, Howard, Carmine or datakoll. But for anyone with the coordination of a skunk sprayed squirrel Ergo or STI has no drawbacks aside from those huge lever bases.

i see the advantage as having the potential to be self-adjusting. whether it actually does this or not is another matter. but if the theoretical advantages were achieved, and precision shifting achievable every time, i think it would be a great thing.

I can't wait to write a virus for the self-adjusting software.

The only problem I heard of was the radio frequency interference problem on rare occasions One complaint had was that the solenoid was not replaceable.

Like I asked a shimano clone at Interbike, pointing to a particularly goofy FD setup, "what's that for?", I ask.."For selling" he answers.
Like disc brakes on road bikes, tubeless, threadless, compact frames, oversized handlebars, etc....many will say what an improvement these things all are but mostly they are for 'selling'.

jeepers, who [censored] in your cornflakes this morning? get off your high horse peter. the bike you rode in on this morning, the steel merckx that you love so much, /that/ is the product of over 100 years of "selling". it's darwinian. what works sticks around. what doesn't, gets dropped. watch, learn and enjoy.

One potential advantage of tubeless tires is that they supposedly improve the handling. Some people have said that they handle as well as tubulars. You are correct that there is a lot of gimmick gee gah technology in the bike industry today. I used to work in a shop and I am amazed they are able to sell some of this stuff. Carbon fiber bars make very little sense when the older 3TTT Superlegerra bars weigh 10 grams more and are far stronger. I have a set and have gone down 5 or 6 hard. The bars did not even bend. I would hate to think how many times a set of composite bars would survive after just paying $300. It's also ridiculous that consumers are paying $3000 with only a 3 or 5 year warranty. Disc brakes do make a lot sense because they do improve the stopping power.
I'm still trying to figure out what the advantages are to electric shifting. Anyone got any suggestions?
In theory you could put your shift levers/buttons anywhere you want on the bike, or have multiple sets of shifters, since the shifters aren't tied to mechanical cables. A TT bike, for example, could have shifters on both the aero bars and the bullhorns. FWIW.

The true advance of cordless electronic shifting will be to relocate the shifters on a TT bike to their proper place: the directeur sportif's steering wheel. Venga, venga!

eh? maybe you should re-read?
You're not holding your breath waiting for that, are you? By the way, the original Mavic electronic rear deralleur had problems, but it wasn't the mechanism. The troubles were mostly centered around the electronics and the wiring in particular. They frequently stopped working due to miniscule amounts of moisture. They did stay in the gear they were in when it quit or you could stop and manually move it over to an appropriate gear. There are no 'clutches" in 'em, contrary to what TK stated.

i saw them on special on cambriabike.com once. but never seen one in the flesh and certainly no tech info.
but don't you think this odd? i mean, mavic's just a marketing company, right? pre-built wheels are meritless and sales are just a function of marketing, so mavic's electronic shifting should have responded to the same treatment...
