Bike Setup

Favorite Ride:
Escalera al Infierno

Summary:
This STI-7900 shifters replaced my STI-7801 ones. VERY comfortable. More so than 7801′s when on the hoods (holding onto them the way Pro’s do). Having read previous reviews, I made sure I would not struggle with set up and rigging, so I also replaced all cables with Jagwire Racer’s complete set as well. I found shifters to have very smooth and precise operation, besides a cleaner look. Set up and rigging posed no issues. Performed flawlessly from the start. And for the record, rear shifter downshifts three cogs when lever actuated three clicks, unlike I read somewhere. 7800 brake calipers, in fact, operate/feel a little better now.

Strengths:
Ergonomics/comfort, functionality, weight, looks, price. Seamless transition from 7801′s. They work exactly the same way. My comfort zone (personal preference).

Weaknesses:
Little harder to install the shift cable housing by the brakes cable (though it results on a superbly cleaner look). Tape the brake housing first, then tape the shift housing. After you install the handlebar tape, you will like the results. Jagwire, Gore, Shimano, listen: now that all systems run both housings taped to the handlebar, you should produce an integral double housing for the handlebar portion of them, to make installation a breeze!!
