Hydraulic disc brake lever LV4

TECHNOLOGY
Bite point and lever reach adjustment
Bite point and lever reach adjustment
The patented technology from Lewis for dual lever reach and bite point adjustment lets you customize the feel according to your preferences for superior performance on the trails.
Reach (tool-free), bite point (with Allen key).
Double oil port design
Double oil port design
The double oil port design makes it easier to bleed the oil.
Enjoy the capacity of the oil reservoir to generate incredible braking power.
Best leverage ratio
Best leverage ratio
Optimise the leverage ratio of structural vertical brakes and the movement path of the tripod bar for a more direct braking force response, ideal for usage environments like XC bikes and climbing bikes that require strong braking response.
Four precision bearings
Four precision bearings
Four precision bearings form the pivot point of the lever.
Each movable pivot consists of precision bearings on both sides providing stable and smooth action.
CNC 7075 T6 4-piston caliper
CNC 7075 T6 4-piston caliper
The 7075 aluminium alloy allows for better rigidity, enhancing overall brake performance while maintaining stable and consistent power.
The 4-piston caliper delivers superior braking power for any situation during testing.
14 mm + 17 mm asymmetric piston design
14 mm + 17 mm asymmetric piston design
The 14 mm + 17 mm asymmetric piston design improves the linear feel of the brakes, balances the pressure distribution of the pads and evens out wear.
Corrosion-resistant hose
Corrosion-resistant hose
The high-quality braided hose is suitable for more intense riding environments.
The standard version LV4 uses 4-layer hoses that have excellent performance advantages, such as high pressure resistance, corrosion resistance, and high-temperature resistance. They also enable more stable operation under intensive brake usage. The internal use of anti-bullet Kevlar fibres with multiple braided layers gives the hose a much lower expansion coefficient than industry standards, providing the brakes with superior rigidity.
Hose material
