I've been perusing the internets for deals on shifter cables. Ebay stores have a decent price on shifter cables by Jagwire. All listings have this message:
Note: Inner wires for shift are NOT inlculed!

What does that mean?

It means you only get the housing, not the cable itself.

I do not recommend Jagwire if your putting some serious km's in in different weather conditions. I thought it was pretty sweet till it completely degraded the performance of my 6700. Going to get some trick kit for it ASAP.

+100 My shifting sucks now. Every mechanic that works on it talks about it. They suggested GORE RIDE ON sealed or extra low friction systems. However, they are like $65...

Gore have an interesting teflon liner that tends to wear out - especially if you have any remotely steeper angle that the housing has to bend through. When that liner wears it will actually end up creating more issues with shifting. Most high quality housings have a teflon liner but I have not had issues with any other than Gore.

Jagwire is great and can last a seriously long time. Don't know why you guys are having issues with it. More frequent housing and cable swaps could remedy your issue. Easiest way to improve the performance of your bike.

FWIW - I have been testing out Yokozuna Reaction cables for a while now. I am a dealer so I like to test stuff before listing it. The shifting performance is noticeably better than anything else I have ever used. Better and much less expensive than Gore.

I'll look into it. FWIW, I have about 3000km on my bike and it's almost due for it's first chain. I'm a mechanic, and I've not heard of bikes needing new cables (inner + outer) in this time frame through normal use..

Oh. That may be a problem then. I have the housing going through a very sharp curve in the handlebar, and it has internal cable routing. I haven't had the amazing shifting that I expect from 7900. Would you pick Jagwire over Yokozuna? Thanks.

Any reason you guys are not simply using Shimano's D/A cable sets?

My bike came with Jagwire. I haven't gotten to change it yet. How does it work for you?

I'll have to second the recommendation for Yokozuna Reaction cables. I have SRAM Rival on my bike with 3T Rotundo bars and the bend is quite sharp. The cables that came with the shifters were gore ride-on and they were TERRIBLE and needed constant attention. These reaction cables have been amazing, improved the shifting and braking and have also made adjustments far less frequent.

Shimano cables have always worked perfect for me BUT that was with 6600 and 7800 not hidden cable systems.

What about Campagnolo options ? I've only used Campy cables, and they seem fine. Am I missing something ?

I have had the same experience.

+2. If you're using Shimano compenents, I don't see any reason not to simply use Shimano cables.

I am not sure what I am running for cables. It is whatever the LBS carries. I just swapped out my outer shifting cable/casings for some pretty purple ones that were on a parts bike I got recently.
I get my inner cables from the LBS, because I have to have tandem length for my rear shifter and brake.
BTW, I know I don't belong in here.

Dude, use the Shimano Dura-Ace cable set. You can get them from JensonUSA for $15 a set.

Cable and housing.

Are these 7900 cables? https://www.performancebike.com/bikes...&top_category=

Can you use 7900 with 7800 shifters?

Is there such a thing as a 7900 cable, or housing? Shimano's tech doc for current Dura Ace says to use SIS SP41 housings.

SIS SP41 cables have been around since at least 2007 (probably longer, but I know there's a Shimano tech doc dated Sept 2007 for SP41)So they can't be 7900 specific, unless they changed them and kept the same part number?

No clue what model. I'm not exactly sure what model I have, but they are Dura-Ace 10 speed shifters. Not sure the cables matter though. I suspect you could use 7800 with 7900 and vise versa.

I'd expect the 7900 shift cables to have a different housing section for the part of the cable that runs under the bar tape. That's how the cables on my 6700 setup differed from 6600 cables.

What do you mean? It's a different length? I ended up cutting it to get the exact fit so I'm not sure it matters. I believe they make the cables to fit the largest bike so if your bike is smaller, you'd end up trimming the housing anyways.

It's narrower (external diameter) than the exposed housing, with only a thin clear layer of plastic over the metal sheathing. It has a ferrule at the end to insert the external brake cable housing into.

We understand that its routed differently. The question is whether the housing is still SP41?

This would suggest that it is: https://bike.shimano.com/media/techdo...9830702962.pdf

Interesting. Based off that, do you think that it would matter if using this cable set with older shifters? I wouldn't think so, but I don't think I've used this set before.

I went searching for images of the new cables and realized I'm probably thinking of the brake cable tails on the Jagwire set I put on one of my bikes. Here's a description of how the 7900 set differs from 7800:

Sorry for the misinformation.
