I am not sure how many superlatives can be piled on top of each other to describe the Louise, but they are pretty close to being a perfect brake, albeit they are slightly heavy. The Louise has proven themselves to be tough, robust and a reliable all around brake. They are powerful, fade resistant, quiet, predictable, with a crisp and snappy feel, and offer excellent control and precision. The On Demand power, allows speed scrubbing or an all out stop, anywhere and at any time, with an easy dab from the lever, giving rise to less effort being required and decreased hand fatigue. The carbon levers look good, are light, comfortable, and have a nice feel without any mushiness. The BAT and the reach adjustment, allow lots of tunability, for rider versatility.
They do have a sharp bite, which may or may not suit everyone’s tastes, but I enjoyed the control and feeling that characteristic brought forth. They are not the lightest brakes, but their power and reliability, and inherent features more than make up for this slight deficient. The Louise is the Uber stopping Queen, and are my current favorite brake.
