Great way to get into electronic shifting - Oct 26, 2015

Like the other review this is my first time using electronic shifters. It was easy to install and very simple to adjust! So much easier to dial in compared to their mechanical counterparts! As for shifting, I've had these for just about a year and I couldn't imagine going back to mechanical shiftIng. Ergonomically, the shifters fit comfortably in my smaller hands, especially when in the hoods. It is also quick and precise. They shift as fast as your fingers can tap the levers! For weight weenies with a large bank account, DA is the way to go. For the rest of us, Ultegra is king!

These were my first foray into electronic shifting. They are great. Very comfortable for my long rides. If you're considering electronic shifting, save your money and go Ultegra, not Dura Ace, sure, the DA is lighter, but it's just not worth the difference.
