Built for riders who need more from their brakes—more pressure, more consistency, more stopping control. The Lewis EB features an oversized axial master cylinder, specifically engineered to push a higher oil volume per stroke. The result: faster piston actuation, firmer lever feel, and greater braking force with less input.
Perfectly matched with a large-volume monoblock 4-piston caliper (2x20mm, 2x21mm), this system delivers superior hydraulic efficiency, ideal for modern E-MTBs, enduro bikes, and gravity-focused trail setups.
Key Features
High-Volume Master Cylinder: Increased fluid displacement per pull, ensuring rapid piston response and stronger braking force.
4-Piston Caliper (2x20 / 2x21mm): Asymmetrical layout for balanced pressure and linear brake feel.
Mineral Oil System: Stable, low-maintenance hydraulic performance.
7075-T6 Aluminum Construction: CNC-machined for optimal strength-to-weight ratio.
Metallic Pads Included
Lever Adjustability: Bearing pivot for smoother modulation and customizable reach.
Weight (excluding hose & pads)
Brake Lever: 132g
Caliper: 202g
Front+Rear Set: 440g
Why It Matters
Standard brake levers can struggle to move sufficient fluid volume when paired with oversized calipers or long brake lines. The EB 20-21's master cylinder is specifically upsized to overcome this—reducing dead stroke, improving bite speed, and delivering consistent lever feel, even under sustained descents or high system pressure.
Made for modern riders. Tuned for power. Built in CNC-cut 7075-T6 aluminum. The Lewis EB 20-21 is the benchmark for trail and E-MTB braking control.
