It depends on what rim; there are very few 13s that clear ZX brakes. Im not too sure about the Libres, but I know the VTO "Libres" clear ZX brakes when you trim off an ear on the calipers. Also, any of the spun aluminum racing wheels (Barts, Aero, Bassett, Diamond) in 13in will clear. I had (and still use one as a spare) a 13in Aero Racing rim on my ZX brakes with zero issues.
