I'm looking for a disc frame along the lines of a Planet X Kaffenback swap-out, around size 50cm, to build an all around bike for the significant other. If only it was a little lighter, that'd be great. Any alternatives in that price range? Thanks.

Edit: Oh there's the "Uncle John" as well, that seems to fit the bill.

The Nashbar X frame is available in 50cm. Pretty budget friendly too.
