Those wires need to *snap*. I've done 3 builds now (9000 stuff but I assume the same) and all 3 had some wire that I was too much in a hurry to snap in place, but it would work until jarred lose.

Not for a TT rig, just a spare road bike. Wanted something "worry free" and I'm already 11 speed (campy).
I'll go back through and check all connectors with the tool again and see if it will charge tonight.
It won't charge, no lights illuminate on the junction (thought there may be *some* energy in the battery to illuminate), and the BCR2 lights don't illuminate when I plug it in.

So I lost the ability to shift into my biggest and smallest cogs a day ago, out of nowhere. I thought maybe some dirt was binding the cables so I gave it a wash and fiddled with adjusting the derailler. No luck. Hated to do it but I took it to the lbs where it was purchased. Diagnosis: rear shifter was just dead, no rhyme or reason. ?? Luckily it is still under warranty. (Dura Ace, 7 months old never banged or dropped)

In other news, etube project is very finicky with parallels. Only sees the BCR2 sometimes.

Update: The lbs called and after pulling apart the shifter, the cable was frayed. I hope that this will not be a regular issue.

what's the review on shimano 10 vs 11 speed? I hear that the 11 is smoother, but I don't know if that's because the 11 can use smaller gearing gaps due to the extra cog, or if it's because of the newer design in the shifter that allows the shifting to be smoother. if the former, then it shouldn't matter in most situations, because the smallest 7 cogs on the 11-28 is exactly the same, while only the 11 has one extra big cog that makes shifting smoother. If the latter, how great is the difference? I can definitely see a difference between my 6800 and 6700, but my 6700 needs new cable housing, so it's not a fair comparison.
anyone?
anyone?

Front shifting is greatly improved. My 11sp 105 shifts to the big ring with about half the effort of my 6700. I also like that there's a little less of a need to change cassettes for different races. I used to go between 11-23 and 11-25 depending on RR/crit/hills/etc. Now I just stick with a 12-25 (moved away from a compact crank) for most if not all of my races.
This may not be the case with Ultegra and above, but I've noticed that the 5800 rear shifting is a bit squishy. It does seem to require less effort than 6700, though not as drastically as the front shifting, but it seems to lack indexing affirmation. It works fantastically, just more a "feel" thing, I guess. Squishy to me may be plush to others.

if you are using that cable, i'd suggest going with the older DA series of shift cable. otherwise....you need to be diligent about checking/replacing cables.

this is 6800, no? i believe there has been a bit of an issue with the newest shimano cables and the coating applied. it is slick as hell....but it also wears off a bit and can gum up/jam up the works. i use it for brake cable and like it, but i hear it is more an issue with shifters cables.
if you are using that cable, i'd suggest going with the older DA series of shift cable. otherwise....you need to be diligent about checking/replacing cables.

9000 uses a thick polymer coating that can shred. Slick as **** though. 7900 uses a very thin PTFE coating. Not as slick but it doesn't shed.

I am going out for a ride now with the new cable, wondering if I'll notice the difference.

I have Di2 so I only have the 9000 brake cables, but it's noticeably better than 7900. The combination of carbon wheels, Black Prince pads, 9000 brakes and cables, it just works really well. Good stopping power, good modulation, low effort.

I spend the majority of my time on disc brakes.
Either (hydraulic) XTRs or cable actuated BB7s. Both are miles ahead of DA in the rain. And, I'm not talking about stopping power; stopping power is pretty much irrelevant on 25mm tires when it's raining. But, in terms of actually WORKING, and then modulation once they (instantly) engage, it's a different league. Aluminum or carbon rims, it doesn't matter. And, you can build a 6.8kg disc brake bike pretty easily, given modern technology.
My next road bike will definitely be equipped with discs.
