OP, if you're not opposed to having the bike look a little Fredalicious, you don't need a new fork.

Wrap about 1.5 inches up from the fork ends in old tube, then put PLASTIC p-clips on (the kind you get at the hardware store to guide cables).

Presto! CF-compatible (low-compression), reliable, weatherproof (ghetto looking) fender attachments! Bolts & nuts probably required.
