Electronic Shifting and questions
Was not sure what forum to post this in. Notice that many good bikes have the electronic shifting?
How reliable is this system now?
With electronic would this guarantee 100% accurate shifting all the time. no more readjusting due to stretch cables?
Now do the shifters and derailleurs have batteries in them for this.?
how long do the batteries last? as i am thinking with the Mt bike if u have electronic shifting, the batteries would die quite fast if one is trail riding all the time.

There is a battery, but I would think shifting the front would take more power than the back. I wouldn't say 100% accurate all the time, but there are no cables to stretch.
Teams in the TdF are using it. They wouldn't be if it wasn't reliable.

the battery is on the frame , the controller runs little servo motors , I think. they move just far enough .
mechanical derailleurs work pretty well , these days.. if you can test ride the Electronic shifting bike
it's a bigger city than here. go for it!

Other than no cables to stretch (which seems like an easier fix than futzing about with a servo), what's to be gained from an electronic shift?

Once electronic shifting is set up, that's it. You only have to recharge the battery for any maintenance because there is no fatigue of the cables or anything like that. I've heard the battery can last over a year without any recharge.

The gripe for me, is/ was mainly the cost. When i bought Shimano DA-9000, 9070 was twice the price. New Ultegra 6870 seems to be a nice choice though.

One of the other mechs in the shop went for a Cannondale EVO with a DuraAce Di2 system this year. Doesn't make him any faster but trim is automatic in any gear and he likes the sound. Long term durability and battery life apparently aren't issues but ... I still ride one bike with DT shifters and have no issues with that system myself.
Even a 12lb techno-wonder is just a bicycle and you still have to pedal it. Personally I like simple.

Simple is best. Maybe I'll try one out sometime, just to see.
