Inner cable size - Shimano
I am thinking about replacing my shifter cables on a Shimano STI Tiagra system with brifters. REI has cables in 1.1 mm and 1.5 mm sizes. I just read that 1.2 mm is the standard size used by Shimano. Will the 1.1 mm cables work, or do I definitely need 1.2 mm cables? I was planning on using the old cable housings.
Thanks.
Thanks.

1.1 is fine. Go with new housing too.

1.1 mm will be fine. If the housing is several years old and/or has been exposed to bad weather with some frequency, new housing is also worthwhile. Be sure to get "SIS" or index-shift housing. Don't use brake cable housing and DON'T use the shift housing for brake applications.

I would definitely replace the housings. I think the housings are at least as important as the cables when it comes to shifting performance.
