Hope has announced the release of its all-new Tech 4 brake levers. Drawing on the brand’s more than 25 years of experience, the new disc brakes feature increased power and improved modulation compared to the outgoing Tech 3 brake systems.
Hope says the Tech 4 lever has “an increased hydraulic and mechanical ratio”. This improved ratio provides a linear relationship between the pressure of the brake and lever force, making it more intuitive to modulate.
Improvements have also been made to the seals, which Hope says are all new for the purposes of reducing friction.
The lever blade pivot also spins on roller bearings, allowing for a reduced master cylinder piston return spring rate, which translates to a lighter lever action, reducing rider fatigue.
Combining these improvements, Hope claims there is a 30 per cent braking pressure increase over the Tech 3 for any given lever force.
The Tech 4 uses a hinged clamp to reduce weight, as we saw with the XCR launched last summer , making brake-lever removal easier and quicker, and improving ergonomics. The reservoir’s surface area has been increased to lower its height.
If you bleed the brakes using Hope’s bleed kit, the bleed cup will attach to a bleed-specific reservoir lid. With the change in shape, Hope says the bleed kit will remain the same but there will be a revised reservoir lid to support the Tech 4.Shifter integration with the latest Shimano or SRAM shifters is also said to have been improved, now offering 30 degrees of angle adjustment.
