Avid X0 Trail: New four-piston disc brake with only 340 grams - Now with video!
After the heavy Code downhill brake, Avid is now offering a lighter four-piston brake for Cross Country to Enduro. Despite its very light weight, the X0 Trail has adopted some of the features of the solid Code.

Only 340 grams for a four-piston disc brake (front with 160 millimetre disc) is a real statement. The newly developed X0 Trail should have more power than comparable brakes in this weight class.

Technical highlights of the X0 Trail
The four-piston brake calliper works with 14 and 15 millimetre pistons. As with the Code, the brake lever rotates in two sealed ball bearings for low resistance and a good lever feel. The sometimes wobbly pressure point adjustment has been revised and is now more stable. No tools are required to adjust the reach. For the aftermarket, the brake comes with a carbon lever; original equipment manufacturers get it with an aluminium lever. According to Sram, the brake pads are a mixture of organic and sintered pads, which have a special shape and size. Code pads therefore do not fit in the X0 Trail. The brake is available in silver and black.


New X0 brake
In addition to the completely new X0 Trail, the previous X0 disc brake with two-piston technology has also been revised and slimmed down. The all-rounder should now only weigh 315 grams. To achieve the weight target, however, the X0 does not have a pressure point adjustment. However, the lever width can be adjusted without tools. A choice of silver, red or black colours is available.

New rotors and mounting
It's not just wheel sizes that are changing. With the additional disc size of 170 millimetres, Avid is also bringing momentum to the existing standards for brakes. Whether the market needs such a fine gradation in 10 millimetre steps remains to be seen.
In future, Avid will no longer use the small CPS washers for brake mounting. Due to the greater precision on the part of frame and fork manufacturers, multi-dimensional alignment is no longer necessary.

First test drives
On the first test laps in Finale Ligure, the X0 Trail showed itself from its best side. In addition to the already very good lever ergonomics, the lever runs very smoothly and defined thanks to the new bearings. We were also unable to complain about a lack of braking power or problems with stability.
