First, triple crank. Yes, for 2016, Campy still offers a triple crank:
Second, integrated shifters and triple - Campy ergo levers are still triple
compatible. In fact, the current Athena is triple compatible with 11 speed:
Third, agree that Campy triple crank gearing are 30/42/53 or 30/39/52:
But I believe the 30t small ring is still 74mm bcd, so you can actually
substitute a smaller ring down to 24t?
Also, it looks like Shimano still offers triples in Ultegra, 105, Claris
(what's that?!) and Tiagra. However, they are only for their 10 speed
groups. Haven't seen anything for 11 speed, so it may not be available.
