Hydraulic disc brake lever LH4

TECHNOLOGY
Bite point and lever reach adjustment
Bite point and lever reach adjustment
The patented dual adjustment from Lewis for lever reach and bite point allows you to customise the feel according to your preferences for superior performance on the trails.
Reach (tool-free), bite point (with Allen key).

7075 T6 CNC aluminium four-piston caliper
7075 T6 CNC aluminium four-piston caliper
The 7075 aluminium alloy provides better stiffness, enhancing overall brake performance while maintaining stable and predictable power.
The four-piston caliper offers superior braking power for any situation during trials.

Lever blade length increased by 6 mm
Lever blade length increased by 6 mm
The lever length has been increased by 6 mm for a more aggressive lever ratio. With our dual adjustment system, achieve increased braking power without sacrificing reach.

Asymmetric piston design of 14 mm + 17 mm
Asymmetric piston design of 14 mm + 17 mm
The 14 mm + 17 mm asymmetric piston design improves the linear feel of the brakes, balances the pressure distribution of the pads, and balances wear.

Four precision bearings
Four precision bearings
Four precision bearings form the pivot point of the lever.

Each mobile pivot consists of precision bearings on both sides, providing stable and smooth action.
High-quality K28 hose
High-quality K28 hose
K = Kevlar, 28 = 28 woven strands per inch, the K28 series hose is stronger than the traditional 4-layer nylon hose, with a 40% increase in Kevlar usage, utilising the latest weaving technology, the highest density advances in history, according to our experience, the new series has brought a noticeable change in braking feel, which can be perceived as a very firm braking sensation. This offers a better option for cyclists.
