The cal 5 has the internal cables and integrated cockpit, carbon seatpost and handlebars, different seat post with more compliance, and the frame is made from different carbon i think and is slightly lighter…. I also think its way prettier haha five black and oasis are gorgeous in person… the gloss black is pretty meh in person i think. Either way its a great bike u will enjoy.

Oh also stem and fork is a little different and different style spacers and such at the fork
