I've read about one person who tried this somewhat unsuccessfully but I was wondering if anyone has had any luck running a Shimano Alfine/Nexus with a segmented cable housing run? It looks like the housing from the Nexus cassette joint to the chainstay cable stop will be a tight squeeze since they are not parallel with each other.

Done this with no issues on my personal bike. If the chainstay stop is placed aprox 4"+ from the cassette joint the casing can simply conform into a shallow "S" shape. Andy

I have done it more than once as well with no issues. Currently running a 7 speed Nexus on one of my own bikes with the cable running down the seat stay because the cable stops are on the top tube. Just made for a neater install.
Also put an 8 speed Nexus in my tandem and used segmented housing, again with no issues.
That bike has since been sold.

So I assume you attached a clamp on chainstay? Any recommendations? Mine is brazed on and is pretty close to the cassette joint. Waiting for my yellow and brown washers to show up or else I would just try it. Thanks

Good to hear. Did you use the bike's brazed on cable stop or did you attach one farther away from the cassette joint?

On the bike that I ran the cable down the seat stay, I ran housing from the rear stop on the top tube to the cassette joint. I have never used the chain stay cable stop on any IGH installations as it makes for too tight a bend to the cassette joint.

Assumes cable pull on the cassette joint, when not changing gears, is undesirable.

I was under the impression that full housing allows for a slacker cable and hence less pull on the cassette joint without impacting gear changes. Of course this requires housing to be of higher quality to minimize compression over the longer housing.

Segmented housing requires a tauter (compared with full housing) cable with perhaps negative effect on cassette joint. Any slack in the cable shows up between cable stops and needs to be taken care of before the cable pull can change the gear.

When you use segmented housing, is there any difference in the tautness of the cable for derailleurs and IGHs?

I just installed the nexus with segmented housing and after adjustment was surprised how slack the cable is when I returned the shifter to first gear. So far shifts great and lines up in 4th gear like it's supposed to

I found a chain stay stop and installed it right at 4 inches and so far everything is working well. Thanks

I see. I forgot to mention I'm installing a clamp on cable stop farther down the chain stay to make it work. Will post a picture when I get to 10 posts.
