The Hope Tech 3 keeps the key features of the Tech Evo master cylinder but has improved ergonomics, power and integration on the handlebars. With it’s revised caliper the E4 offers a wide range of riders the power and adjustability they need.
Tech 3 Master Cylinder
Hope have kept the key features of the Tech Evo master cylinder and worked to improve the ergonomics and integration on the handlebars. The Tech 3 master cylinder offers a slight increase of power of about 5% over the Tech Evo.
Popular design features of Tech Evo remain the same, such as the reach and bite point control (BPC)adjustability. The piston is actuated by a cam and a roller system to eliminate any free play and initial friction. The classic split clamp design makes the master cylinder easy to install on the handlebars without having to remove anything else.
Some riders have previously commented on the relative bulkiness of the old Tech and Tech Evo master cylinders, sometimes making it hard to fit the master cylinder around already clogged up handlebars (shifters, fork and shock lockouts, telescopic seat post controls etc). Hope have worked hard to make the new Tech 3 master cylinder easier to integrate on the bars although it does entail losing the ambidextrous design.
The Tech 3 master cylinder is now directly compatible with any Shimano I-Spec type shifter meaning no extra mount is required to attach the shifter to the master cylinder and for those using SRAM shifters Hope have designed a slick and minimalistic direct mount adapter.
The one piece caliper is CNC machined from a solid billet of 2014 T6 aircraft spec aluminium alloy. The E4 caliper uses four identical 16mm phenolic pistons which gives more usable power to the brake, whilst keeping our legendary "feel".
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.
Hope are makers of CNC precision cycling components such as braking systems and accessories, hubs, bottom brackets, wheelsets, lights, stems, headsets, quick releases, tools and cycle clothing and merchandise.
