Boy, am I out of date...!

Looking to replace my old 2005 bombers. They have a straight 1 1/8in steerer, QR axle, old style brake mounts (are these called IS ?) - not the new post mounts.

They are fitted with the 1st generation Hope Mono Mini calipers and rotors, which I'd like to keep.

Can anyone recommend a suitable replacement please ? Say in the < 200$ range or thereabouts?

Many thanks
