CNC machined from T6 aluminium alloy, the M4 offers power and adjust-ability via the external-reach-adjustable Tech Evo lever and super strong 4-piston caliper. A special linkage system eliminates play for extra reliable braking.
Tech Evo Lever
The Tech Evo Lever is CNC machined from a solid billet of 2014 T6 aircraft spec aluminium alloy with an ambidextrous "flip-flop" design for use on either side of the handlebar. A split clamp design allows easy set up and choice of positioning.
The Tech Evo lever, features a redesigned piston, lever and pivot assembly with external ‘on the fly’ reach and bite point adjustment dials. The lever linkage eliminates play in the lever giving a consistent and reliable feel to the brake. Further developments include lever pivots with bearings for smooth, rock free use and improved ergonomics with a perforated lever for extra grip and feel. A double sided reservoir lid makes for easy bleeding.
The M4 caliper is CNC machined from a single billet of 2014 T6 aircraft spec aluminium alloy. The M4 caliper uses four identical 16mm phenolic pistons which gives more usable power to the brake, whilst maintaining the legendary Hope feel.
A drip free bleed nipple and wide angle fluid inlet connector have also been included, allowing for neater hose routing and cleaner servicing.
Bicycle disc brakes consist of a metal disc attached to the wheel hub that rotates with the wheel. Brake calipers are attached to the frame or fork along with pads that squeeze together on the disc. The way it is attached to the bike will be either by IS (International Standard) which has two holes facing the disc or Post Mount, which has threads going into the fork. Disc brakes have been successfully used on motorbikes for decades, and are the principal choice there. The primary benefit of disc brakes is that they perform equally well in all conditions including water, mud and snow. This is due to their position closer to the hub and away from the ground and possible contaminants like water, which can coat and freeze on the rim in colder temperatures. The pads are usually made from metal sinters or an organic compound instead of rubber. Water acts as a lubricant to rubber but not metal, therefore disc brakes maintain their stopping power in wet conditions. They also avoid the problem that rim brakes have of wearing out the wheel rims, especially in muddy conditions, as well as the requirement that the rim be straight. Disc brakes offer improved modulation of braking power and generally require less finger effort to achieve the same braking power. The advantages of discs make them well-suited to steep, extended downhills through wet and muddy off-road terrain, common in freeride bicycle riding.
