Yes, the ones I have installed pull a rocker. I haven't personally found it any harder to pull the dual brake over a single, but that could be just me. I made the tuning adjustment at the brake caliper itself front and back with the brake pad positition adjustment set-ups. I went with the first one mainly due to lack of space on my handlebars
. My wife asked for the second one on hers to make it less confusing and make it easier on her hands (she's still healing from a broken hand from a door prize).
To each thier own, I agree completely. That's where we digressed from, as I recall.
