    Can any road bike be upgraded to DI2?

    Just curious if all road bikes can be upgraded to Ultegra DI2? Reason I ask is because I absolutely love my Ridley Excalibur and can't see selling it anytime soon. It seems like it's about a 2009 model and is currently spec'd with 10 Speed Dura ace 7800. I have ridden a few bikes with the Electronic shifting and am completely sold. Problem is this bike was built before any of the DI2 shifting so not sure how this would work. Seems like bikes nowdays come DI2 ready or compatible. I google searched on here and couldn't find any answers. Any information would be appreciated. Also right now my bike has all external cable routing. Is this gonna be an issue? Thanks...

    Not going to be an issue. Full external routing is available. Shimano makes everything you need for it.

    yup, the only potential show-stopper to using it on an 'old' frame is the same thing that would stop you from being able to use any new road group (mechanical or electronic) on it and that would be if the rear drop outs aren't spaced at 130mm. Even then you could probably do it if the bike was steel. But that's all moot because your bike is many many years past that being a potential issue.

    Would you suggest since my bike is an 09 that I upgrade the Cranks, BB brakes etc also. Or do I just need the Brifters, and Derailleur's? Right now my bike has the FSA cranks and Dura-ace canti brakes...

    DA brakes are nice, don't get rid of those. We have a bike for rental in the shop that has old DA calipers that stop better than SRAM's new Red HRR brakes ('15). Although the hydros were on carbon rims...

    I would just get Brifters/Derailleurs for cost-saving. Shimano cranksets are super expensive and with DI2, you probably won't notice a shifting difference.

    Also, aren't FSA carbon cranksets lighter than DA aluminum?
