Yikes! Di2
I was talking to the man in the bike shop yesterday about how to wire up the Di2. He said to being in everything and let him look at it so I did.
He said that the lever only used a single connector and that was prone to some sort of troubles that I don't think he was knowledgeable about. That all of the new levers had three connectors each. As an engineer none of that makes sense to me but I'll believe him. This set was only $600 and that's less than the cost of the levers alone on eBay. Does anyone know what the problems with the levers is and how a couple of switches need "upgraded" software that won't work in these levers? |

You only can't mount sprinter or TT switches in parallel with default ones. Only the first DA was weird. Lou |

I suspected as much since my analysis of these levers is that they are nothing but switches. |

ST-R785 The interface is SM-EW90-B Same shifters I have on my cross bike. Going strong for almost 6 year now. Each shifter has one E connections which you connect to the junction box A underneath the stem which has three or five E connections (if you only use three stub the other 2). Junction box A connect to junction box B near or in the bottom bracket. The battery and the FD and RD are connected to the junction box B which has 4 E connections. Lou |

Does anyone know what the problems with the levers is and how a couple of switches need "upgraded" software that won't work in these levers? The back of the stem unit appears to take a 5 connector push-on-style connector. That would make sense so that nothing could get into the connector in rain etc. But I cannot find any reference to a connector like that and the local shops really don't know much about it. I would think - one wire each to the levers, one wire to the battery supply and one wire each to the front and rear derailleur. I'm sure that the bottom bracket junction block gives you the ability to have reasonable length wires from the stem unit and then you can buy the correct length wires to the front and rear derailleurs. |

Ah, the price of "progress"! Not true. If you have installed a modern Shimano cable FD with adjustable "converter," routing to the anchor point is not really intuitive. https://si..shimano.com/pdfs/dm/DM-FD0002-05-ENG.pdf It takes some investigation and measuring to determine the routing. Even old RDs had alternative anchor points for different speed systems. People would strip the aluminum threads on old FD cable anchors, which is not a problem with plug-and-play eTubes. The benefit of progress is a really smooth shifting. Running/connecting Di2 eTube is not difficult. Ikea furniture is harder. Most phone apps are harder. -- Jay Beattie. |
