Thought I would give back to this thread for all the help it has provided me. By the way, thank you exxxviii, without this thread I would not have been comfortable doing a DI2 upgrade myself, never mind going the Junction A box into the bar idea. Super sexy!
I did a DI2 upgrade on my Gen 2 Speed Concept. It went extremely well and I am very happy with how it ended up. I wanted to get more reach on my bike and the only way to do it without a headache was with a DI2 upgrade. Good excuse as any to go electronic!!!
Heres the part list all bought online. For us Canadians, I had the joy of worrying about getting slapped with tax, service fees etc. on this all. From my understanding we do not have to pay duty on bike components, so if you are importing make sure you make it EXPLICITLY clear that you are purchasing bike components. However, its still a hassle if it gets dinged, as you have to send a letter to the boarder agency and whatnot.
I spent around 1500 CAD for the DI2 parts, wires ect. and I ended up buying a bunch of parts from Canadian sites during Black Friday. This was to mitigate headache from shipping from the UK. Prices ended up being around the same +/- 50CAD doing this. I did buy some parts from Ribble and Sigma Sports. Funny enough, there was a postal strike in Canada so all the canadian parts were delayed. Not only that, but the UK sites were actually extremely fast... I got my UK orders in like 4 days, over 1-1.5 weeks from the Canadian sites! Sigma sports has a nice feature as well where you can prepay tax, which decreased the headache. TBH I would shop sigma sports again even though its from the UK. With shipping included I basically went with what was cheapest and also convenience factor. I avoided Probikekit because I heard nightmare stories of their shipping. Stuck to bigger retailers from the UK or Canadian sites. By the way, be prepared to make spreadsheets to get this whole thing done. You have to buy it piece by piece... thank you shimano... so I ended up making a spreadsheet and tracking the prices for around 6 weeks. Then I knew the baseline price for them in CAD and tried to see when the prices dropped locally or abroad. This worked really well. TBH I would have saved minimally buying it before or on Black Friday, as the priced barely changed. Best prices were from the UK. Black Friday allowed me to buy more locally from Canadian retailers. The Canadian retailers ended up being the same price I would have paid for them in the UK, but I had less fear of it getting dinged at the boarder.
I also over bought wires due to there being some packaged wire combos on Ribble. I also got some DI2 wires from a Slowtwitch user when I purchased some aerobars from him, which actually went unused. Guess you can never have DI2 wires though in case one gets damaged. The multiple sizes also came in handy when I ran into some wire issues in the build; if I went by the "buy only what I planned" route I would have been screwed and I would need to buy more wires.
My part list:
ST-R9071 Dura-Ace Di2 STI 2x11 Speed (Brake Shifter)
SW-R9160 Dura-Ace Di2 TT Bar End Shifters (Pair) (1 Button, plug)
Ultegra Di2 R8050 11 Speed Front Mech
Ultegra Di2 R8050 11 Speed Rear Mech
Dura-Ace Di2 9070 2 Port TT Handlebar Junction Box
DI2 Cable W/ Junction B (4 pack cables + 1 Junction B) X2
EW-JC130 B Junction Wire
DI2 Wireless Unit
Battery (Shimano BT-DN110 Di2 Battery)
Battery Charger (Shimano BT-DN110 Di2 Battery)
Assorted DI2 grommets (4 oval, 4 round)
Also for my upgrade, I got
Bontrager Mono Plug
Enve TT Extensions
I did not opt to get the carbon seat post for the Speed Cocnept; yest it comes with a "DI2" mount... but you can actually stuff the internal battery in the aluminum seatpost and save $300! Plus I like the aluminum seat post as I can use my bike stand with it. The carbon one would require another stand... and more $$$
Unfortunately I made a few boo-boos when I bought this all. First, I wanted the 2 button ST-R9071 Dura-Ace DI2 brake levers over the newer single button brake sifters. I assumed they came with female DI2 cable attachments but... well... it comes with male cable attachments. So... I bought a B junction 3 piece wire (EW-JC130) for the brake shifters and as a result, I lacked the junction B box to make this work the way I planned. Fortunately I was conservative in ordering the wire lengths and I was able to use the junction B wire to connect to the front shifter and the Junction A. I might go and buy one more Junction B box for the front to allow me to take the front apart a bit easier. The B junction EW-JC130 wire is baarely enough to get this all wired up. I plan to cut the aero extensions a bit as well so this would make it less of an issue, but I would prefer being able to take apart the front end without worrying about the EW-JC130 wire configuration.
The biggest PITA was trying to get the drive side BB out. The shield+bb had basically no room for my Park Tool BB remover to grasp the BB. I ended up having to shim the Park Tool open which allowed my to take the BB out eventually. Not a huge fan of the design but otherwise I did not encounter any notable disassembly hiccups.
All in all, with taking this thing apart, installing DI2, inspecting all the parts, putting it back together and indexing ect. it took around 12-15 hours- I took my time but I made sure each bolt was greased again, cleaned the parts and basically did an entire rebuild of the bike. Cable routing was not too big of an issue- I followed the existing Mech cables and made a few DIY wire cable tools. One of them came in handy for the battery as well. I bought 2 cheap shifting cables and glued a magnet to each side. Then I could route them from both sides and connect them in the middle, and tape the cable to one guide and pull it through. I still have to purchase a new brake cable for the front and a screw for the brake cover as it seems to be almost stripped. Fortunately its trainer season for the next 4-5 months at least so no need for those parts! I am also really happy I took the whole thing apart. Not only do I know everything about this bike, but I got a chance to clean those hard to reach places and apply some TLC to them. I do not know how detailed your LBS will be on cleaning the bike, but there is something to say about getting at every single screw and bolt. I also understand why you might want to spend some $$$ to make someone else do it... it can be a PITA. However its totally worth it imo.
I was able to hide the DI2 Junction A box in the extensions. I was worried about having to file down the internal bar diameter and also the Junction A box but the bars actually came with the internal diameter shaved down from the factory. I guess the ENVE Aero Extensions are "ready" for this whole project from the get go. From what I could read online, there was a few manufactures that seemed to make sure the ID of the bars fir the Junction A box, but in the end its hit and miss. I was lucky I had to do no work, but I was ready to sand that sucker down if required. The outer "holder" for the Junction A box had to be sanded down as the Speed Concept aerobar mount got in the way. I filed down the outer frame for the A box by around 30-45% and it fits perfectly now. I plan to cut around 20mm of the aerobar so I can bring them back a bit. Right now they are a tad bit long, but they are a HUGE improvement on the "Ergo" Bontrager SC bars. I can actually get fully stretched out now and my shoulder is much happier.
I'll add some pics of my DI2 build once I figure out how to upload them. Let me know if you have any questions
