I have been using the very sweet Louise Carbon BAT brakes for just over three months, and they have turned out to be my current favorite stoppers. They are powerful, with good modulation, are quiet, fade resistant, highly tunable and have the bling carbon levers.
Louise Carbon BAT
The Louise Carbon is designed and manufactured in the fatherland Germany (actually in Laichingen), and for 2010 the Carbon’s come in a nifty race white finish. The Magura line of hydraulic disc brakes, includes the weight weenie Marta series, the budget Julie, the Louise and the gravity oriented Gustav. It is interesting, that except for the ultra powerful Gustav, they all have girl names? So considering the Marta’s pedigree, the Louise reminds me of the East German woman swimmers, Anabolic steroid enhanced power machines!
They use an open hydraulic system, with an integrated reservoir and an expansion chamber for fluid temperature control. The aluminum caliper has PM mounts, an adjustable hose fitting, and uses two injection molded composite pistons for less heat transfer to the brake fluid, and the pistons are magnetized for brake pad attachment. The pads come in two models, the default Performance version for maximum power, or the optional Endurance version for longevity. The rotors are sold separately in 160, 180 and 203mm sizes (6 bolt IS or Centerlock) in either the default Drilled SL or Venti rotors. Magura has a wide assortment of adapters so their PM caliper can fit any bike or fork. The hydraulic fluid is Magura’s Royal Blood mineral oil, and the brakes are bled using their Easy Bleed Technology. The aluminum master cylinder, has a carbon lever with reach adjust and Bite Adjust Technology (BAT), and attaches to the handlebars using their Quickfit split clamp system.
