Hey guy’s,
I believe that i have been through most posts on this topic, however I want to 100% sure.
I’m a recent P5-6 owner with Dura Ace Di2. I bought the SW-R600 2button so-called climbing shifter. I want to mount this on the right magura lever to control the rear der. I have the 5 port junction box.
Now, with all the soldering hacks on the P5 thread with cateye buttons and so forth, I believe most of these solutions were before the ETube protocol became mainstream.
The question…Since I already am fully E tube equipped and have the 5 port junction box, isn’t it just a matter of mounting the SW-R600 switch, snaking the wire through the base bar, and conecting to the 5Port junction box.
I already have the SM-PCEinterface device to update the firmware.
I should be good to go right? Basically plug & play.
No need to hack anything.
No need to hack anything. That said, you’ll need to make sure that the wire would be long enough.
Also, if you are so inclined, you can program another climbing shifter and place it on the LHS brake lever and use the e-tube stuff to configure it so you can shift the FD
Yes! I had to buy the little/tiny junction box(essentially serving as a connector) and a Shimano extension wire.
Even with the tiny connector box, everything fit within the stem area and cover plate. So, no exposed wires for me.
NP3 with Ultegra Di2 here. The wire on the climbing shifter is not long enough. You’ll have to figure out how to get it longer. My LBS said that Shimano doesn’t recommend disassembly, soldering etc. (there’s a gigantic surprise). So, I figured I’d start with their suggestion which was to mount the shifter where we could. That meant the shifter is mounted in a position where my little finger can activate it when I’m climbing on the bull horns. And, the wire is taped to the bottom of my bar, running back to the connector box.
I had originally wanted to put the shifter on the brake but I was surprised at how well this position works. An added advantage is that it is closer if I have my hand on the flats while climbing. So far, I’m really happy with it.
Had that not worked I was prepared to buy one of the longer wires, take apart the shifter, cut its wire and solder in the new one after cutting it to length. Not sure if I would have soldered directly into the switch or just wire to wire.
The only issue I have is that the shifter is so damn big. Could have been made half that size.
I don’t have a second shifter on the left for the front DR, figured I wouldn’t really need it and there have only been a few occasions where I might have wanted it.
