Dura Ace (9100) & Ultegra (6800) cables identical?

Road Cycling “It is by riding a bicycle that you learn the contours of a country best, since you have to sweat up the hills and coast down them. Thus you remember them as they actually are, while in a motor car only a high hill impresses you, and you have no such accurate remembrance of country you have driven through as you gain by riding a bicycle.” -- Ernest Hemingway

Dura Ace (9100) & Ultegra (6800) cables identical?

I'm upgrading my new bikes Ultegra 6800 groupset to Dura Ace 9100. Are cables identical? It would make installation easier if I could install all the components without pulling out all the cables. Thanks!

I don't know how you can change the shifters without pulling the cables.

If you are an active rider you should replace shift cables yearly anyway. You really can't judge the new shifters with old cables.

It's fine.
You indeed can't change the shifters without new cables, but I just put a fd-9100 on my 105 bike no problem.

Hopefully whoever put on the cable ends on your bike did not go overboard crimping them or you may have a tough time reusing the cable. Just be really carefully feeding it back through the housing. If you catch a loose strand trying to insert the cable into the housing you can easily trash the cable (I won't use cables without all of the strands in place).

Gear or Brake ? or Brifter , that's Both..

Loosen the far end clamp, Pull the whole assembly out,

Put the new stuff on and make up all new cables & housing. , then If you want to swap back you have the whole set up together in a Bag..

Then carefully remove the terminal on the end or cut it off and seal the end with superglue. Remove the cable and reuse.

Do your budget a favor and replace them with standard $1.50 Shimano stainless cables when they're ready to be replaced. The polymer cables are a waste of money for what you get.

FYI...Shimano cables have a polymer coating, supposedly for more friction free movement. It's proven not to be the case in my and quite a few others experience. It shreds up and binds, especially within the STI lever- and if it jams up good in there you can potentially ruin the lever. Go with straight up stainless cables.

...and installing new groupset? Trying to save the cables is being pennywise & pound foolish.

Yes, do that if you have no interest in these groups shifting as well as they are designed to.

Each individual R9150 component is 100% compatible with 9070 as well as 6870 Ultegra Di2.

Not my experience I put those polymer cables and housing on my Ultegra 6700 and it made a huge difference. I never miss a shift. The cables that route thru the top tube like my Wilier and wrap all under the bar tape bind easily. The polymer eliminated this and I always use jagwire die drawn cables and housing the b st I think under normal conditions.

Works fine. No polymer shredded and binding in the shifter either.

Well...if you consider cable binding up in the STI lever as shifting well...

If you really want the group to shift well, toss the suckass Shimano housing and go with the likes of Nokon compressionless housing, which although finicky and requiring tedious & precise installation, results in significantly less friction.

I only use the Cordz now. The new steels cables go in a drawer.

On 3rd year with Power Cordz. No reason to change if you leave them alone.

If I wasn't going Di2 next these would be the next choice. I've heard good things.

Cordz on all the Di2 rigs. Of course brakes, not shifters. On the MASI they went smaller DIA Cordz now and the brakes have sharp edges. I'm not 100% sure these won't cut. The FELT on the rear only. Venge is on year 3 with same set. Smooth as silk.
These 3 bikes are Di2.

Nice, I'm going hydro disc with the Di2...Gonna be a fun bike.

My "ultimate" "All-Road."

Going to do a 42/32 in the front, 10-42 xx1 rear... XTR Di2 derailleurs with Dura Ace 9100 Di2 Hydro/disc STI & brakes.

I call it a "Two By One." Meaning two different 1x drivetrains on one bike.

Essentially I have 1x mtb via the 32 and 1x CX via the 42.

Lauf Grit fork...

Wait, wait. Did we just agree on something?
