campy long cages seem to be out there but they are $$$...so please forgive the heresy!
42t is the smallest you'll really find for that 144BCD crank, although 41t do exist, you can have chain issues. Interestingly enough, a fellow on the CR list is developing a 40t ring to fit without spider modifications (40t/5 arm = a nice even number and avoids some 41t issues).
