As for the cable housing, the type mentioned in the other post above is the Shimano recommended one. Seems to be low compression coiled housing, similar construction to brake housing. Originally, in the 1980s, the SIS cables were also wound. This was before the SP40/41, linear strand was used.[/QUOTE]


I was able to locate the flexible cable housing OT-RS900 at LBS. I've already replaced the stiff one with the new one which was easy to install.

Tested the shifting on the stand, and everything looks ok.

Thanks for responding
