The MT8 SL Disc Brake is ethereal in its lightness. In fact, it's Magura's lightest brake ever. However, this doesn't mean that it's light on stopping power. The architecture of the brake lever is based on Magura's proven Marta radial master cylinder design. Only here, it's made of a carbon fiber reinforced thermoplastic rather than die-cast aluminum. Magura ensures the quality of this process, called CarboTecture because it does the manufacturing in its own facilities. It developed this new technology in order to create a brake that excels in all four categories of its design focus: weight, heat stability, braking power, and ergonomics. The light overall weight is evidenced by the numbers, but how does the brake feel? We've ridden them, and while they lack the all-out power of the 4-piston MT7, its power and modulation, especially given its weight, is truly impressive. Magura has been in the game for a while, since 1893 to be exact, so it knows the importance of details. For instance, the banjo fitting on the MT8 SL caliper is one great example in its ability to pivot. This means that you'll be able to route the hose cleanly along frame no matter what the housing guide and mount configuration are. The two piston, forged aluminum caliper allows for a 1-piece design. This adds stiffness to an otherwise superlight caliper body. The pistons are made of thermoplastic, which helps to insulate the fluid from the heat generated in the brake pads. This improves the brake performance on steep, enduring descents. Changing pads has been made easier than ever since the calipers use a top loading design. This way, you're able to change pads without removing the wheel. The CarboTecture master cylinder is stiffer, lighter, and stronger than comparable parts made of aluminum or magnesium. In a truly inspired move, Magura created both sides the same. You're now able to run your levers on either side of the bike, and it won't matter because there's a bleed screw on top and bot...
