[Closed] Swapping from XC717 rims to Stans arch ex

Running hope pro 2's on Mavic XC717's and while they seem pretty tough, the narrow width doesn't allow me to run 2.25 tyres at the lowish pressures i would like.

Been looking at the new stans ztr arch ex which is the same weight but a fair bit wider. Swapping the rims across seems pretty straight forward but all this talk of ERD and needing new spokes is making it look a bit of a pain.

ERD of the stans seems to be 541. ERD for the mavics seems to range from 538-540.

What are the chances the spokes will be the correct length?

Cheers,

Ryan
