Best shifting system ever created by far, nothing even close. Best front derailleur system and ditto the rear. Makes the Campy and Sram topline groups look prehistoric.

shifter cables, housings,barrel adjusters = lmfao

shimano leads and wins again

they'll trickle it to Ultegra next and keep refining it

true innovation by Shimano and now even their shifters look better than campy LOL

When Di2 doesn't cost an arm, a leg, and your firstborn son, then maybe it can 'kill' something.

For now, and for most, it's just a curiosity.

I am going to use it to build a remote controlled bike. I'll just ride in the car next to it.

I am not even curious and I have ridden it.

I don't know if it will make it that far. Right now the price is way out of reach for even those who want the system. To drop it to Ultegra would seem to be self-defeating - Ultegra is a great system at a attractive price point.

As others have said, I also believe, E-shifting is still just a curiosity. I can't imagine that the performance is that much better. We're still dealing with a chain, chain wheels, cogs and derailers. Same system, just differing actuators.

But, as always, time will tell...

I've ridden it and agree that it is awesome but something tells me that I would forget to charge the battery at some point.....I even had a chance to pick this up for $2500 but the timing was not right to pull the trigger.

Kills them? Well in price no doubt it's a killer. Performance, only have a 5 minute ride to discern, but it was really sweet I agree. First off the Di2 is the coolest looking gruppo installed, I mean wow. I rode my bud's P4 TT rig over Christmas break and it was in a word, sweet. The bike is amazing and the gruppo is just wow.

Little tidbit on Di2. My pal with the P4 got caught out in the rain while on vacation in Florida a few weeks ago. His LBS has been working on the shifting ever since and it's still not right. He has an SRM crankset and all of it's functions are fine, but the Di2 is screwed up royally. I dunno how sold I am on electronic shifting until this gets resolved. Price point is crazy. I would still take Record 11 over the Di2 at this point and I know my buddy is about ready to die with his triathlon season coming up. The LBS has offered a lot of remedies, but not able to sort it out yet. Next step was to scrap the entire electronics package.

true innovation? what did the innovate? mavic came out with electronic shifting years ago with the mavic zap. shimano might have perfected something, but thats it.

i'm not totally sold on a bike that requires batteries to operate.

hardly....

What an ignorant post. Di2 is so expensive that it can't be trickled down unless Shimano wants to cut their sales volume to nearly nothing. The stuff is not affordable. If you cjeck out a large number of on-line stores, the majority don't even bother offering Di2 because it won't sell.

About the cheaprest I've seen a conversion group is $2800, without the cranks and brakes.

I can buy an entire Athena 11 group for under $800 and even a full SR group in under $2000. I can convert a bike to 11 speed for $350.

RAdio Shack had a Di2 Do-it-yourself Kit shortly before they signed Lance and the boys. They took it off the shelves since Lance is partial owner of SRAM. Word on the street is they'll have it available in time for Christmas as part of a Remote Controlled Bicycle Kit for Alberto Contador. MSRP is supposed to be around $3000.

Regardless of how inexpensive it might become, or how well it performs, there will still be those of us who will feel that the electronic side of it simply polutes what is perhaps the most beautiful simple machine that man has ever created. A finely crafted bicycle that is 100% mechanical and 100% human powered is a beautiful thing. A Di2 equipped bike does not fall into that catagory.

mostly in price. Thank you for such an informative, enlightening thread. I feel more fulfilled when I can experience such epiphanies.

Im retrofitting D12 on my windsor wellington 2.0 since the 2200 doesn't shift so good nemore. Yah it costs 5 grand and i paid about 400 for the bike but thats 5400 for a sweet shifting bike which is prty reasonable I think. I couldnt get the battery to mount right but i just jb welded it on and it seems too be holding so far so good LOL!

All 3 work great and any Fred who tries to claim one is "better" than the other two, is well just another Hot Air Fred. The reality is none of these groups is gonna make you faster or ride better. Lots of hype and BS spun mostly by mostly middle aged Freds with nothing better to do with their time but try to convince others their stuff is better than someone else. Hot air losers, LOL

Although Di2 is a huge improvement over previous systems, it has some huge hurdles to overcome besides the price. Bicycle manufacturers will have to modify existing designs or introduce Di2 only bikes to accommodate for the new wiring system & battery pack.

The only manufacturer that is making a Di2 compatible bike to my knowledge at present is Trek. Its easy for a Pro tour team mechanic to change or replace the wiring system or processor if it gets damaged in a crash but what about the avg joe?? If you don't have a Di2 compatible bike, you're running all the wiring down exposed tubes. If anyone remembers from the old days of cycling computers before wireless, it was very easy to damage your wires & kaput no data.


Secondly what happens when Shimano 5 yrs from now introduce their version of 11spd or more?? We're talking about different cage geometries, so its a physical constraint & not a software one.
