Here is what enduro mag said
“There is a lot of new innovation in the Magura MT5, perhaps most notably its new magnetiXchange replacement pads that magically lock themselves into the correct location. As the Magura’s use Royal Blood mineral oil, bleeding is also a less toxic affair than some, and a simple process. The MT5 brake comes standard with two organic brake pads per caliper, but these are also compatible with the four individual pads from the more expensive MT7 brake. The only thing we missed was tool-less reach adjustment (they require a T25 torx key), and it has to be pointed out that the excitingly named “Carbotecture” lever clamp material looks a little cheap, as do the fast threaded clamp screws. However, some of our testers liked the utilitarian look and we could certainly not fault the performance. We liked that the lever can be mounted on either side and found the long blade was easy to locate in a comfortable position. The ergonomic aluminium lever has space for one- or two-finger braking. However, with power like this, using two fingers would be like riding into a wall.
During testing, braking torque and deceleration were brutal – but there was a delicate sensitivity present too, like a rhino in ballet shoes. The Carbotecture fibre composite material is certainly light, offering almost Saint-rivalling performance, but at a big weight and cost savings. Throughout the tests they proved reliable and the lever bite point did not shift once; again and again they provided dependable stopping power. Magura have shown that you can have it all, and with a five-year warranty, they take the Best in Test award with ease.”
