I'm in the process of upgrading my supersix from mechanical to di2 - first time I've done it. Any tips for the routing? I can't seem to get the wires through from the junction a through the headset, the end of the wire doesn't seem to fit but a hydraulic hose which is bigger does, so a bot puzzled as to why it's not. I'm also having trouble with routing to the rear derailleur but this might just be perserverance! I'm already using a routing tool if that helps.
Just be patient. I built mine from a bare frame that had no feeder lines like new framesets have, I got lucky through the chainstay as it went first time without even using a routing tool.
Around the headtube was more tricky but some patience and wiggling made it happen. For the Di2 wires being so light and flexible, I found gravity and a bit of shaking helped it find its way, orient the frame so the direction you want the wire to go is downwards. Brake hoses are a bit thougher since they're much thicker and stiffer. For both, it can help if you have L-shaped hex wrench with a long long section and a short short section or a J-bend spoke and use that from the headset openings to push/pull the wire and/or hoses in the correct direction.
Another trick is to first route a piece of string, it's easier since it's smaller, lighter and more flexible, you can even use the vacuum trick to suck it out from where it should, then attach the end of the string to the wire and pull it out, gently and wiggling again where it's tight.
Funny thing, once I had everything routed on mine and the bike almost fully assembled, I was not 100% happy with the feeling of the steering as the brake hose seemed to restrict turning the bars freely, it pulled a bit, so I started over again with a different routing and different, simpler wiring so I wouldn't get anything affecting steering, thankfully I had not yet connected the brake hoses to the levers. As you can guess, the second time was pretty easy.

Anyone else have issues getting the axle to thread properly with the Sigeyi direct mount hanger? Had to loosen it up and leave it loose so I could wiggle it to get the axle to thread in, is that right?
Mine went on without any issue, as easy as the OEM hanger, just lighter and nicer.
