User Manual:

Better Leverage Ratio
Optimize the leverage ratio of vertical structural brakes and the motion trajectory of the tripod bar to obtain more direct braking force feedback, which is suitable for use environments such as XC bikes, climber bikes with high requirements for brake feedback.

Dual Oil Ports Design
Dual oil ports design, more convenient oil filling. Invrease the oil reservoir capacity, better for four-piston caliper.

Bite Point & Lever Reach Adjustment
Lever reach(tool free), bite point(with allen key)
Lewis' patented dual adjustment of lever reach & bite point allows you to customize the feel to your preference for superior performance out on the trails.

Four High Precision Bearings
Four precision bearings constitute the pivot point of the lever blade.

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