911 plus bike?

Hi,

I'm about to buy a lovely a 911 (993 carrera 4) and need some help. I race triathlons so need to occasional transort a bike. Appreciate the cars not designed to be people carrier but does anyone know if you can put a bike rack/roof bars on this particular model ??? If so can you let me know where? Initial searches have drawn a blank (oddly enough there easy to find for a boxster!)

Thanks
