    My frame has no holes for internal cabling, so I'd have to go for the external setup.

    I also had to replace the Rival brakes with Ultegra to match the shifters.

    I did put a SRAM 11-32 cassette on so that I can make it up the hills around here. It's not approved, but it works fine. There's a little bit chain-derailleur rubbing when I go small-small or big-big, but the noise isn't bad and it tells me that I'm cross-chaining.

    I love the Di2. I probably shift more often just because it's so easy. I highly recommend the switch.
    Thanks, I'll look for the pix at your convenience. I have DA 7900 right now, so I'm hoping/confident that I only have to replace the shifters/der/wiring, leaving the rest of the group in place. I would have a shop do it as well.

    I sent you a PM with a link to a bunch of pics. Make sure that they use the white (or black) wire guides. My shop held the wire in place with black plastic ties and it was tre ugly. They gave me the wire guides and I put them on myself.

    Iirc existing Di2 is upgradable to 11 speed via a firmware update and all you'd need is a new rear cassette

    DI2 makes it so you don't have to worry about shifting. Just push the button, it happens. Shift into small ring under load, whatever. For me, it's nice to not have to worry about shifting on fast rides.

    Red is sleeker looking and lighter and like all mechanical, there is the satisfying feeling of feeling your shifts (although I'd say less so with sram mechanical vs shimano).

    My opinion though is DI2 is better to get already hung on a bike, and since you can get a great deal on a new or slightly used ultegra di2 complete bike I'd go that way.

    Thank you RoboCheme, the pictures worked and are helpful in understanding what the external routing will look like. I have the smallest size frame, so I think I'm going to get the internal seatpost battery, otherwise there won't be room for water bottles.

    Robo, would you mind sending me the pics as well? I am in the same boat, considering a new groupset for my Ridley

    Had you asked last month, I would have replied SRAM. However, in just less than 20K miles, my SRAM Force, 2 speed brifter has quit working (won't retain the big chain ring detent). I'm told it's non-repairable. Contacting SRAM doesn't seem to be an option, see

    no email address.

    So, hunting a replacement on ebay.

    Also stopping by any local SRAM authorized retailer will get you sorted right out..

    I had an issue with my REd FD and they took care of it without a receipt and without going to the original shop it was bought at..

    I would go Ultegra Di2. SRAM Red with Yaw is very finicky. It only works with specific chainrings and cranksets and is very touch to setup perfectly. The biggest plus for Ultegra Di2 is the front shifting. It shifts to the big chainring under load better than SRAM Red does with no load.

    I went with SRAM Red, mostly because of the 2 pound weight advantage.

    In my experience, the shifting is great. It's better than any Dura Ace group I've had (although the last generation of D/A I've used is 7800). The Yaw red FD worked fine for me with an FSA crank, which I used while waiting for the New Red Quarq crank. With the Red crank it shifts fantastic. It took a little attention to detail, and following the instructions specific to the Yaw derailleure to set it up. But a year later, it's still shifting fine, without so much as turning a barrel adjuster in 12 months.

    From all accounts, I'm sure your right that Di2 shifts better up front under load, than Red. However, Red shifts pretty darn well, so I'm not sure how much better it gets.

    So for me, great performance, 2 pounds lighter, and the aestethic of a manual group, and one less battery to worry about (admittedly a minor worry) trumped slightly better electronic shifting.

    Thanks for the great update! Sounds like Red is working well for you.

    I have used both and while Red's front derailler is good, to me Di2 is unimaginably better. I didn't believe it till I tried it. I'd describe it like this:

    * Red lifts and slides the chain up the ring onto the big ring along with your push

    * Di2 instantly puts the chain on the big ring the moment you click the button

    It's hard to describe how instant it feels. The first 20-30 times I used it, I had to keep checking to see if it had actually put it on the ring because it didn't seem possible (despite hearing the "whir" of the motor). It was too quick and too "light" to believe. Even when I stood on the pedals going hard up a 7% incline, it still went just as easily (although the sound was more clunky). It's as fast as the best rear derailler can drop the chain down to a smaller cog.

    I do agree that SRAM Red is lighter but it's not 2 pounds lighter, it's 620 grams lighter which is 1.35 pounds. And the new 6870 Ultegra Di2 is only 1 pound heavier than SRAM Red.

    (aside) For mechanical, I actually think Campy Super Record is even better than Red on the front derailler (although I have not used Red 22). It was such a perfect, crisp, exact shift with less force needed than on Red. I also liked how Campy not only gives you 5 trim positions (to eliminate cross-chaining) but lets you simply push through them instead of needing to click through them one by one.

    Hills are where I get dropped, or not, often bc I am just a few watts short. 1.3 lbs 'tips the scales' in favor of Red. When I get dropped, it's not shifting, it's power to weight.

    It may feel that way, but science does not bear that out.
