*caveat* this works with Hayes/Avid IS 160mm front and rear adapters. No idea on other sizes/brands.
Really?!

That's good, I'd probably have much more luck finding a Hayes adapter here... I need an adapter to convert the fork's IS mounting things into PM onto which I can mount the Avid brake, 160mm. Would it work in this case then?
Thanks,
