Do Shimano 6800 cables work in a 6700 groupset?

should be fine
personally would use the teflon coated rather than new polymer coated cables as i've seen the polymer coating rub off on my rear brake (certainly for the rear brake anyway)
the pre-lubed SP-41 outers are spot on0 -

Did it rub off from the exposed part of the cable or from somewhere within the outer?0 -

i've had this too, it seemed to build up around the end caps but didn't seem to affect performance though.www.conjunctivitis.com - a site for sore eyes0 -

exposed part near the end cap.
also, if you catch a cable on something, likely to remove some of the polymer0 -

I'm guessing that the cable is stainless steel and hasn't rusted. If it is only the exposed part that has rubbed off then I'm not too fussed. If it rubs off when inside the outer cable then it will lose its low friction property.0 -
yup, stainless underneath.
i wouldn't expect it to rub off inside the outer (not for a long time anyway)0 -

its the older ptfe coating that used to wear off - causing increased friction - on the DA7900 gear cables which is one reason the change, puting on a set of 9000 cables on my little used 7900 gs was like night and day, very pleased with the difference.
i do believe the issue is with the 9000/6800 brake cables, something to do with the older brake clamp not griping the new polymr cable.0 -

That's what I read. But if that is the case then it can be remedied by taking the polymer off the end of the cable where it is clamped. If it rubs off easily with use then a bit of sand paper should do the trick.
The description of the 6800 cables is the same as 9000 is there any difference?0 -
Polymer cables on last generation groupsets make a huge difference.
I have 7900 on one bike and 5700 on another.
Fitting polymer cables on the 5700 took out all of the vague feeling and were pretty much on par with the standard 7900 setup.
Polymer cables on Ultegra or Durace are just beautiful and are only a little bit heavier in operation than the current groupos.
The Ultegra cables are a little thicker than the Durace ones and are a little more susceptible to ham fisted mechanics stripping the coating during fitting due to poor casing cuts and kinking the cable.
If you use the polymer cables, use the correct endcaps with the dick that sticks out the end cap as well as using the shimano cable grease if you are using SP41 off the roll that is not lubricated like buying a full cable kit is.
Easily the best inner cables on the market.0 -
Are these the sort of cables that are being talked about?:

No, those are the Teflon coated, last generation cables. This is the new polymer version. http://www.wiggle.co.uk/shimano-road-gear-cable-set-with-polymer-coated-inners/Are these the sort of cables that are being talked about?:

Right, thanks.0 -

No idea what you mean there, the mind boggles :roll: But I got the full cable kit so I expect to have all the relevant pieces. I also got a fourth hand tool and a pair of cable cutters that will reshape the end of the outer casing and crimp the end cap. I'll be especially careful not to strip the polymer from the cable as it goes through the casing.0
