I replaced the 50/34 FSA SL-K compact double with a 52/39/30 FSA SL-K triple. The lowest gear is 27 gear inches with the new triple versus 31 gear inches with the old compact. It's the edge I needed for the steep grades on long rides. The highest gear is now 124 gear inches versus the 119 gear inches with the old crankset. Nice!
If you ask me why I went with another expensive carbon crank I could go on about weight and maybe other tech stuff but the truth is it just looks reeeeally good. I sold the old compact so the damage to the wallet wasn't that bad.
