In no way is Avid new to the multi-piston game. But, unlike the X0 Trail Brake, its prior offerings were solely intended for gravity use, and sadly, could easily double as boat anchors.
Lucky for the all-mountain and enduro set, Avid didn't just go digging into its extensive parts bin to pair an X0 master cylinder to Code calipers. Instead, what you get is a completely new four piston caliper that won't weigh down your rig. The resulting two-piece caliper houses 16mm and 14mm pistons.
This combination provides the perfect balance of modulation vs. power, which allows a controlled speed scrub to full-on, eyeball elongating power. The minimalist caliper uses a post-mount, and the line is connected via an adjustable banjo bolt on the back. This allows a clean installation on a variety of frames, including the current trend towards chainstay mounts.
At the levers, Avid took the time to beef things up from the standard X0 offering. Instead of a hollow pivot rotating on a bushing, the X0 Trail's lever rides on dual sealed bearings. This adds strength and long-lasting, smooth action to the picture. Avid's Taperbore technology is employed here, but it features all new internals like a relocated, easy-to-access bleed port and an air trap to automatically isolate any tiny bubbles from the system.
The X0 Trail's master cylinder has lever reach and pad contact adjustment to accommodate individual rider preferences, and the clamp is matchmaker-compatible for plenty of handlebar/shifter/remote mounting options. Connecting the caliper and lever is a high-strength, braided polyester hose that ensures lever input isn't lost to expansion.
The Avid X0 Trail Brake is available in the colors Black Anodized and Polished Silver. Please note that these brakes are sold individually as either a front (950mm hose) or a rear (1800mm hose).
The X0 Trail Hydraulic Disc Brake was specifically designed to meet the do-it-all demands of trail riding. At only 340 grams, one could easily assume that this brake would not be powerful enough handle the unforgiving terrains. Guess again. The robust 4-piston dual diameter caliper and ground-breaking lever pivot bearing produce more power than any other brake in its class. On top of that The XO Trail Hydraulic Disc Brakes feature Contact Point Adjustment™ to dial in the point in the levers throw to where the brake actually engages for a more customizable modulation. The TaperBore Technology™ integrates the master cylinder into the levers to create an extra-sleek design and reduce weight. The top-loading pad feature enables disc-brake pads to be installed without taking off the wheel so that you waste less time installing and more time shredding. The X0 Trail Hydraulic Disc Brake is a fist full of features, ready to pack a punch.

Honestly, a lot of the below reviews are correct. These brakes do require maintenance, but not nearly as much as people make it out to be. Maybe I got a good set, who knows, but they functioned perfectly out of the box. After one full season (May-Oct) of riding between 2-7 days a week in Utah, they have performed better than any brake I have ridden.
Out of the box, they do require more adjustment to get dialed, once they are, they are the best. Organic pads and 4 pistons stop me on even the fastest descents. If you dial the contact all the way out, then use a zip tie between the pads to set the contact as close to the rotor as possible, you get instant engagement and then as the pads wear, you can dial the contact point in. Once you?ve ran out of this adjustment (a month or so of riding for me) you just do the process over again. I bled my brakes once this season, and really didn?t need to after I discovered the above trick.
I found myself riding some popular descents in Park City, one of which has a nice cheese wedge lip into a downhill into a flat left corner, and going in to the whole setup faster than ever before, because even over the chatter braking bumps in the landing I knew I would be able to grab enough brake to make the corner successfully. The slow speed modulation and working techy sections in Moab are no problem, and shutting it down while in a sketchy situation is optimal.
These brakes are not for everyone. They have more power than the XT?s and bite harder. They do require some maintenance, but if you are lubing your chain, and adjusting your derailleurs once a month, it doesn?t hurt to take an extra 15 minutes and adjust your brakes. If you are looking for set it and forget it, then look towards other brakes, but if you are ok with a little work to make your
