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 to your preferences for superior performance on the trails.
Reach (tool-free), bite point (with Allen key).
Dual oil port design
Dual oil port design, making it easier to bleed the oil.
Enjoy the oil reservoir capacity to generate incredible braking force.
Best lever ratio
Optimize the lever relationship of vertical brakes and the movement path of the tripod bar to achieve a more direct braking force response, suitable for environments like XC bikes, climbing bikes with high braking response requirements.
Four precision bearings
Four precision bearings form the pivot point of the lever.
Each moving pivot is made up of precision bearings on both sides providing stable and smooth action.
CNC 7075 T6 four-piston caliper
The 7075 aluminium alloy provides better stiffness, increasing the overall brake performance while maintaining stable and predictable power.
The four-piston caliper delivers superior braking power for any situation during testing.
14 mm + 17 mm asymmetric piston design
The 14 mm + 17 mm asymmetric piston design enhances the linear feel of the brakes, balances the pad pressure distribution, and balances wear.
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 provide more stable performance under intensive brake usage. Internally using Kevlar bullet-resistant fiber with multiple braided layers results in the hose having a much lower expansion coefficient than the industrial standard, giving the brakes superior rigidity.
Hose material
1. PVDF and Teflon
2. Spiral filament winding
3. Braided layer of Kevlar bullet-resistant fiber
4. Tensile and corrosion-resistant sheath.
