Magura USA Blood Brake Fluid $18.00
Mmmn, precious blood. Vampires and brake rebuilders love Magura blood. It's the recommended hydraulic fluid for all Magura hydraulic brakes. It's a 10-weight mineral oil, unlike the stuff found in drugstores, which is usually 30-50 weight. The drugstore stuff will make the brake sluggish and could lead to brake failure, but if that doesn't put you off, the following small fact should: use of any other fluid besides Magura Blood will void your warranty. 16 ounces is enough to do eight bikes worth of Magura hydraulic brakes.
