Magura Louise Carbon BAT Review

Brakes Components Pro Reviews


Bottom Line
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.

    very informative review of the Magura brake.

    what kind of video camera do you have on handlebar? How do you like it so far?

    Nice review, I have a pair myself (with alloy levers)and have same comments to make. Sometimes thought about the Martas but cannot really see the benefit and really like the facility of the Louise levers to be released by split clamp system. Now if they made a model with the levers of the Louise and the calipers of the Martas…hmmm. What did you put down to the Martas requiring additional pressure on the levers as both models share the same brake pads now?
