26 to 27.5 spokes

[anon4]

I have a hub I'm considering reusing but its on a 26" rim. I want to rebuild it as a 27.5. The current spoke length I believe is 198mm, what size would I need assuming the same lacing pattern?

Depends on the ERD of the rim in question.

What hub is it or the hub flange diameter also need to know the actual rim erd other wise you/we will be playing guessing games.

There are plenty of spoke length calculators on the web:

To name but three. I tend to use the last one listed if that helps.

Thought it would be simpler, I will use the calculator, thanks

Thought it would be simpler,

No chance

It is only simple with the right spokes length and using the correct X pattern for the spoke length.

Also you don't want to get the spoke-rim angle so that the spokes are bendy - here is some helpful info:
