hey doods, wonder if anyone can help

i'm about to purchase some new brakes for my other half. at the moment she's got my old Avid Juicys – they've been shite from day 1 – and i'm looking to replace them with some deore M575

her forks & frame both have iso mounts. on CRC the deores come with post mount brackets and you get the discs separately

am i right in thinking i can just use the avid discs and the exact same avid brackets? they are 185mm and 160mm. will these be compatible with the shimano stuff?

yup.

Can I have your old Avids?

Doesn't work the other way around though, Avid calipers with Shimano adaptors can be hit and miss.
