The 287V pulls more cable than any other drop-bar lever, just barely enough to be acceptable for "V-type" brakes.




The 287V moves the cable up as far as is possible. Moving the pivot down would cause the lever to be difficult/impossible to operate from the hoods.

I'm running 287-v levers on my dirt-road Miyata and offer two tweaks:
1) Don't use the special noodle. Route the housing into the rear of the lever like any other areo lever.
2) Use the Tektro 916/925 mini-v brakes. These require less cable pull than the full-size V brakes.
FWIW, this is one of the few bikes I've ridden where I'm in the hoods a lot and don't find them uncomfortable. I do have small hands, mind you.

Ok, well, I didn't run them under the tape either. Perhaps that's why it worked fine for me.

Here's what it looks like. It's not pretty, but it's utility!

Just barely? If they're designed for V-brakes, shouldn't they be perfectly matched?

First of all, standard "V-type" brake levers, like other levers made for straight bars, bend away from the handlebar to provide good clearance. Levers for drop bars need to bend toward the bars or you wouldn't be able to reach the bottom of the lever with your fingers from the drop position.
When I first started tinkering with my first bike, I didn't know that drop bars and straight bars had different diameters, so I naturally ordered regular V-brake levers. They didn't fit, of course, but the only thing that was wrong was the mounting. They would've been an almost perfect fit otherwise, and reaching them from the drops would've worked fine - I lined them up and tried! And my hands are average in size, or maybe even on the small side for a male.

I don't have any need for brake functionality from the hoods, since I never ride in that position (no forward stop to prevent me from losing grip if I hit a bump or a pothole), so it hadn't occured to me that that could be a problem for some.
