When I first started to use the brakes, I kept locking up the rear, since I wasn’t used to that much power, since these babies are powerful suckers, and I had to use the rear more gingerly. No matter where I was riding or the terrain I was on, I could stop on a dime, and bring my momentum to a quick standstill. The modulation was good, but not on par with the Marta’s, but their Uber power more than made up for it. By varying the amount of force on the levers, you had amazing control and precision, which was always predictable, and could easily scrub off speed anywhere, although their bite (sharpness) might not be for everyone’s tastes, although I liked it just fine. The strength and bite of the brakes, allowed great versatility in technical terrain, and helped with trial moves at slow speeds. The levers had a comfortable, solid feel without any mushiness nor flex, felt good in my hands, and they looked sweet in carbon.
I slammed the brakes as hard as I could, taking them onto the ugliest long steep descents that Colorado has to offer, and they performed admirably, never fading, and allowing a good deal less hand fatigue, even when pulling for prodigious periods of time. I like to ride the brakes on steep terrain to maintain my speed, and the Louise took a lot less effort to scrub speed, just a light feathering was all that was required. I used my Marta’s on the same terrain, and my hands ached, were tired, and scrubbing speed required additional pulling pressure overall. When the brakes got wet in the typical Colorado rain deluge, they would maintain their stout power and control even when soaked. They have stayed pretty silent overall, and only required an occasional sanding of the brake pads to silence them.
The Drilled SL rotors worked just fine, and I never had any warping issues, and they were pretty silent even when pushing the brakes fade limits. They are not the lightest rotors, but they have been reliable and very durable. Even with all the mileages and hard braking I have done, the brake pads have been long lived, and their wear has been minimal. The Performance version of the pads, which I used most often, suit the braking style of the Louise better than the Endurance series.
