This is an odd question. The sentiment that the only security here is physical security is correct. Think about the following:
The Shimano Di2 components are not mated/matched to a specific computer or instance of E-Tube software. So there's no 1:1 relationship.
Therefore, any computer equipped with the SM-PCE1 or SM-BCR2 programming cables can be used to ...
I'll declare an interest in that my company is the senior (Main) Technical, Service and Warranty Centre for Campagnolo in the UK - but having said that. the Service Centre work that we do for Campagnolo is not all of what we do - we supply general technical training to the industry across the board and I am also part owner and Technical Director of a ...
Possibly the bike has a cassette size that the Dura-Ace Di2 rear derailleur does not support.
The current DA RD-R9150 (short cage) rear derailleur has a max low sprocket size of 30 teeth whereas the Ultegra RD-R8050-GS (medium cage) will take up to a 34. If you have an 11-32 or 11-34 cassette, you do in fact need the Ultegra GS derailleur.
SS and SG ...
A late answer, but perhaps it helps some people. I used Vmware and not VirtualBox. However: I had to disconnect and connect the usb port in VMWare, even though Windows noticed that usb was connected to Windows. Shimano DI2 disagreed. A software reconnect of usb inside VMWare fixed this.
The solution suggested about D-Fly does not fix this. I have D-Fly ...
Perhaps instead of password protecting it, you might want to think of ways you could detect that the device was tampered with. I'm not certain how often you would change settings or plug into it, but you may want to cover the port with security tape or something similar so that you are aware when somebody has been messing with the equipment. This may not be ...
According to BikeRadar, "The battery unit as well as the wiring for XTR Di2 are identical components to the ones used in Shimano's electronic road groups. The battery can be mounted on a bottle cage, in a seat tube, frame and can even be contained within the steerer unit of certain forks (via the use of PRO's new Tharsis components)."
You require these items, all DI2 compatible:
rear derailleur mechanism
di2 controller box (normally strapped to the bottom of your stem)
di2 brifters, or di2 shift buttons that strap to your handlebars, but mean you can keep using your brifters as plain brakes.
battery (one for a wired system, or several for a wireless system)
wiring harness, and secure ...
My mountain bike doesn't have Di2, so this answer is based on my road bike Di2 experience..
1) Whether there are options like 44/33/22 in the crankset dropdown, and
The e-Tube project software will only list crankset options that are actually available in Di2 series hardware. What I mean by that is if you're using a road bike Di2 Front derailleur (...
Nobody has tried yet, but it's likely that some people will, one of them being Terry at Bettershifting.com.
As background for other readers, the Di2 system battery contains the central processor. Shimano just announced 12s Dura Ace and Ultegra groups today. Time trial and triathlon bikes are a very small share of the performance bicycle market. Shimano ...
From what I can see, the answer is no, at least directly. Shimano has made a new standard for the E-tube wire which is thinner and sleeker, but also has a new, smaller connecter. The new cable physically won’t connect to the old shifters.
Whether or not adaptors will be available from Shimano or others is something I can’t answer at the moment.
I've heard of loose connections between the shifters and their cables causing this sort of issue. In one case in particular, the connector didn't latch properly and the bar tape pulled it out, so it would seem OK when tested but not when riding.
In general if you've got battery and part of the system works, the connections are one of the first things to ...
Yes, of course, that's possible. You just plug the cables into the brifters. Peel the grip-covers forward and you'll see unused ports underneath. Those may be used for sprinter buttons or for climber buttons as well.
But I'd suggest you replace a triple box by a quintuple box (Shimano SM-EW90-B 5 Port Di2 Junction A) to make the connection easier without ...
My rides are generally 80kms a week usually by myself at an average of 23kms per hour with average cadence of 65. Would an aero bike make a difference?
For the type of riding you are doing, aero bike will make a small difference, one that you are likely not to notice very much. Aero bikes do however have a much stiffer ride, so you will likely find the ...
According to Slowtwitch Shimano needs one junction A in the system otherwise it won't work.
You can skip junction B.
It may cause some interesting wiring.
The 6700 series (EW6770) junction may make things smaller/easier.
This is the same answer for all current e-tube di2 systems. (6700,6800,9000)
If you have a bike with Shimano Di2, physical security should be paramount - I'm not sure why an unsavory person should even be physically near enough to the bike to be able to make those changes. And they'd have to be carrying the right cable and everything.
It seems like a highly implausible situation to occur, and certainly which should not occur ...
No, there are not any male-to-female "extension" wires available for the Shimano Di2 E-Tube system. You can use a junction as you said, or you can use the two-port ANT module. You could also modify an E-Tube wire to lengthen it yourself, if you are handy with a soldering iron.
Turns out that an unnoticed connection from the e-tube app on my ipad blocks any type of connection via the e-tube app on my laptop, charging, or usage generally. So after you've checked all the connections, attempted crash mode, let it sit charging, make sure that you've 'disconnected' any device in the etube app that may have inadvertently connected.
Okay problem solved. Apparently the NOS cable set that I bought came with an SM-EW90-A with really old firmware. After installing E-Tube Project v3.4.5 and restarting my laptop, I was able to update the junction box using SM-BCR2. The RD works without the FD mounted and I was able to make initial adjustment while waiting for the FD.
Thank you for all your ...
You would need to use a PC, and you would need to make sure that the wheels had reasonably close original chain line positions for this to be possible. If not, then no, you can't do this.
Shimano's E-Tube software does allow you to save presets for adjustment and switch settings. That means you could have multiple presets ...
Extension (Male/Female) wires are now available since a few weeks.
You can ask your reseller, they are not on general availability yet.
I got one of them because I moved my aerobars forward and needed some more length
If you have carbon rims (with a carbon braking surface) you will need appropriate brake pads, so as not to damage the rims. You do not have to use shimano brake shoes- most (possibly all?) rim brakes will take any brand of shoes.
There is a carbon rim insert for Dura Ace, which might fit the ultegra shoes. However if there are no compatible pads for your ...
Using Parallels, I was able to get the system to recognize the USB connection by going to the Parallels menu, selecting Devices > Shimano BCR2, repeatedly. After about eight times (4x on/off switching between Mac and Windows), the e-tube s/w recognized the USB device.
No, Shimano's software intentionally disallows you from setting your bike up with a mix of mountain and road derailers. Boycott-worthy, I say.
It's very common for touring tandemists to wind up feeling best served by doing something or other with their front chainring setup that is just never going to work well with front indexing or di2. If you look at ...
You need to install a D-Fly unit. Probably this one: EW-WU111
Being able to use the Garmin in rain and cold weather with gloves is brilliant.
However check if you have the right components: these batteries are ok: BT-DN110 / BM-DN100
I think you must be referring to the new cassette on the second set if wheels.
Sprocket spacing remains the same on Shimano 11 speed across generations. The new Ultegra R8000 cassette will work perfectly well with the 6800 derailleur, maybe even a bit better.
The only trouble you may have is that the cassette may be in a slightly different position on the ...
I just installed a Di2 6770 10spd front and rear derailleur with a BT-DN110 internal battery.
I can confirm that once I update firmware on all the components, eTube does NOT allow me to set up synchro shifting.
Very disappointed considering the battery has all the hardware necessary to support it.
You can use the 785 shifters with Alfine 11 di2 for definite. You should be fine with the other combinations.
I was told by the shimano tech rep in 2015 that any di2 shifters work with any rear end shifting. the shifting switches are pretty dumb and just say up or down to the rest of the system.
FYI Shifting is disabled in a derailleur system where the rear ...
SC-E5003 is not listed in the dealer manual for DU-EP800, so I don't actually know whether everything going on here is going to work and therefore this is a "suggestion" type answer. That said, it would seem like if there was a way to connect all those components together, the way to do it would be use one of the under-the-stem type Junction A ...
