Upgrade to di2

Hi, I would like to upgrade to di2 r8050 on my Cervelo R3 2014 (Ultegra mechanical version). I have a lot of problems with gear adjustement on that bike, and Im tired of it.

But my problem is what do I need to buy. I would like to keep the brakes (Ultegra 6800) and the crank (Rotor) and the brand new cassette.

What parts would I need to do the minimal job ?


Thank you

I'd let a Professional Bike shop do the work for you.. since I sense you will have myriad issues..
selling your bike & buying one already wired up may b a way to go.

shop can set the new one up like your existing bike for fit matching..

If your bike wasn't made with Di2 in considered as an option for it's frame, then you might wind up with a lot of externally mounted stuff that just plain looks ugly. Get a new bike, become one of the N+1'ers. Or give your six year old bike to some kid from a low income family that might benefit from it.

If your sure the high cost of an electronic drivetrain outweighs the lower periodic cost of cable replacement than perhaps consider Sram wireless. You would not need the Di2 external battery and wires zip tied along the outside of the frame tubes.

I've done what you are describing, I re-used the crank, bottom bracket and (rim) brakes, cassette and chain. I had to purchase shifters, F & R derailers, battery (and seatpost shim) and battery charger, A junction, B junction and 7 E-Tube cables of assorted sizes. This system generally runs about $1100. I found Texas Cyclesport to be the best deal at the time (3 years ago) and they did a good job of packaging to fit.

I also did this on a year old Chinese carbon frame designed for Di2 and internal mechanical cable routing and that's the 1st question - is your frame set up for internal Di2 ?. Like others I would not spend this money on an external system based on esthetic reasons alone, forgetting that Di2 is a superior shifting system (IMO) and has required zero maintenance.

Would I do this on a 6 yr. old frame ? - No. Is your current bike 10 spd. ?, that would maybe mean a new crank, bottom bracket, cassette and chain, so add at least $200 to the budget. Is your rear wheel 11 spd. capable ?, not all are.

Begs the question that a certain level of mechanical aptitude is required to get this installed and set up, and you have issues now keeping a mechanical Ultegra operational ?. Do you really want to tackle this ?.

Good site here for add'l info. https://di2center.com/

Thanks for the advices. Im hesitant to sell the bike since I already CLX50 clinchers. The bike also has internal routing. So, I would need to bike a bike with these wheels and di2. They are stupid expensive and on top of that will not be really faster.

Thank you

If you already have 11 speed and internal routing, no good reason not to use the bike you have. IMO you should just have a shop do it for you. Hard to find decent discounts on Shimano parts anymore and you'll have a lot to learn before being able to tackle the job yourself.

One possibility is to buy a new bike already di2 equipped, swap your CLX50 wheels to the new bike, install the new bike's wheels on your bike and sell it. That way you get to keep your expensive wheels and don't have the hassle of retrofitting the di2 drivetrain.

If you have any interest in disc brakes, a newer bike will let you make that change too but unless the CLX50 wheels are disc compatible they will have to be replaced.

Of course a new bike won't be faster. All you are doing is changing the shifting mechanism.

Yes thats an option but my CLX are clinchers. I would need to buy a bike with equivalent disc wheels. Which are stupid expensive.

Wire issue can be solved by Sram wireless.
