Lewis VP Series Carbon-Ceramic Brake Pads

Fade-resistant, quiet, and built for high-speed riding where braking consistency matters.

The Lewis VP Series Brake Pads are engineered for riders who demand strong, predictable braking on long descents and under repeated heavy load. Made from an advanced carbon-ceramic brake pad compound, VP pads are designed to deliver powerful stopping force, high heat resistance, and ultra-low noise across aggressive trail, enduro, downhill, and e-MTB riding. When braking performance needs to stay consistent lap after lap, the VP Series is built to keep control sharp and fade in check.

Unlike standard compounds that can become noisy or inconsistent as heat builds, the VP Series is designed to maintain a more stable brake feel during sustained braking. That makes these pads especially well suited for riders pushing hard on technical descents, heavier bikes, and high-speed terrain where brake temperature, modulation, and reliability all matter.

Lewis LV-S2: XC Weight, Enduro Cockpit

The Lewis LV-S2 redefines the lightweight brake category by pairing a featherweight 2-piston caliper with the race-proven LV4 Radial Master Cylinder. By utilizing the exact same lever assembly found on Lewis's LV4 brakes, the LV-S2 offers XC and Trail riders a level of stiffness, adjustability, and bearing-driven smoothness that is simply unheard of in the cross-country category.

While the caliper is slimmed down for speed, the lever provides the "big brake" feel. The Radial (Vertical) design orients the piston perpendicular to the handlebar, minimizing flex and providing a crisp, direct connection to the rotor. If you want the snap and modulation of an enduro brake in a package light enough for a World Cup race bike, this is it.

The "LV" Advantage (Lever Tech):

• Shared LV4 Radial Platform: The S2 uses the same skeletonized CNC lever body as the DH-rated LV4. This radial design reduces "squish" and flex, delivering immediate engagement that standard axial XC brakes can't match.
  
  
• Frictionless 4-Bearing Pivot: Most lightweight brakes use bushings to save grams. The LV-S2 refuses to compromise, utilizing 4 precision sealed cartridge bearings in the lever pivot. The result is a feather-light lever action that eliminates hand fatigue.
  
  
• Dual Adjustability: Complete control over your setup. Features Tool-Free Reach Adjustment (dial) to set the lever distance, and Bite Point Adjustment (via 2mm Allen key) to customize exactly where the power kicks in.

Caliper & Power:

• Oversized 21mm Pistons: While most 2-piston brakes use 19mm internals, the LV-S2 packs Dual 21mm Stainless Steel Pistons. This massive surface area generates significantly more clamping force, allowing this compact caliper to punch far above its weight class.
  
  
• Featherweight Construction: Despite the overbuilt lever and oversized pistons, the extensive CNC machining keeps the weight at just ~300g per set (levers & calipers, excluding hoses).

Mechanic's Note (Pad Compatibility): The LV-S2 uses Lewis LP-30 / TP-30 brake pads. These are specifically shaped to cover the larger 21mm pistons for maximum heat management. 

Configuration:

These brakes are sold in the standard configuration:

• Left Lever: Front Brake (90cm Hose)
• Right Lever: Rear Brake (165cm Hose)

Note: The levers feature a "Flip-Flop" design. If you ride "Moto Style" (Right/Front), you can easily unbolt and swap the hoses to reverse the configuration.

Specifications:

• Intended Use: XC / Downcountry / Trail / Dirt Jump / Trials
• Lever Platform: Lewis LV Radial (Vertical)
• Pistons: 2 x 21mm Stainless Steel
• Material: CNC 7075 T6 Aluminum
• Fluid: Mineral Oil
• Hoses: Kevlar Braided
• Pad Compatibility: SRAM Level / Elixir / Lewis VP-30 / Lewis TP-30 / Lewis LP-30
• Weight: ~300g (Set without hoses) / ~412g (Complete with hoses)

Lewis EB 20-21: The Heavyweight Champion of Braking

The Lewis EB 20-21 Axial Cylinder Brake is not a standard mountain bike brake. It is a dedicated heavy-duty system engineered specifically for E-Motos (Surron, Talaria, E-Ride Pro) and full-power E-MTBs. When your machine weighs over 100lbs, and you are hitting downhill speeds, standard bicycle brakes just don't cut it. The EB 20-21 delivers the hydraulic volume and thermal mass needed to safely stop heavy electric builds, lap after lap.

Built around a massive Oversized Axial Master Cylinder, this system pushes significantly more fluid than a traditional lever. This is required to feed the monster caliper, resulting in a firm lever feel and immediate piston engagement without the "mushy" feeling common in other brakes.

Why the EB 20-21 is the Standard for E-Moto:

• Massive 20mm & 21mm Pistons: While standard DH brakes use ~17mm pistons, the EB 20-21 uses a gargantuan 2x20mm + 2x21mm asymmetrical layout. This increased surface area generates an immense clamping force to stop heavy electric bikes instantly.
  
  
• Thick Rotor Compatibility (3.0mm): Heat is the enemy of E-Moto brakes. The EB 20-21 is designed to work with extra-thick 2.3mm to 3.0mm rotors (like the Lewis HD220). These thick rotors absorb far more heat without warping than standard 1.8mm bicycle rotors.
  
  
• TITAN Ceramic Insulation: The pistons feature TITAN ceramic inserts that act as a thermal firewall. They prevent the intense heat from the pads from boiling your hydraulic fluid, ensuring your lever stays firm even at the bottom of a 20-minute descent.
  
  
• Braided Kevlar Hoses: Say goodbye to hose expansion. The kit comes pre-installed with T200 Kevlar-braided hoses, ensuring that your hydraulic pressure goes directly to the caliper, not into expanding the line.

Mechanic's Note (Pad & Rotor):
1. Pads: This caliper is huge. It uses Lewis EP-44 Sintered Metallic pads. These are larger than standard bicycle pads to handle the heat and torque of E-Moto riding.

2. Rotors: For best performance, we highly recommend pairing these with 2.3mm or 3.0mm thick rotors. Using standard thin rotors may result in excess lever throw.

Configuration:

These brakes are sold in the standard configuration:

• Left Lever: Rear Brake (165cm Hose)
• Right Lever: Front Brake (90cm Hose)

Note: The levers feature a "Flip-Flop" design. If you prefer "MTB Style" (Right Rear), you can swap them to reverse the configuration.

Lewis SLR Lightweight Flat Mount Road Brake Caliper

Ultra-light construction, larger titanium pistons, and precision braking performance for serious road riders.

The Lewis SLR is the lightest flat mount road brake caliper Lewis has produced, built for hill-climb bikes, premium road builds, and riders focused on reducing weight without giving up braking confidence. Precision CNC-machined from 7075-T6 aluminum and equipped with titanium pistons and titanium hardware, the SLR weighs just 68.5 g for the caliper body alone. The result is an exceptionally light flat mount road disc brake caliper designed for performance-driven builds where every gram matters.

Low weight is only part of the story. The Lewis SLR uses dual 21 mm titanium pistons, which are larger than the 19 mm pistons commonly found in many stock road calipers. That larger piston size helps deliver stronger, more consistent braking force with improved control at the lever. Lewis also engineered a generous 0.3 mm pad clearance per side, helping reduce rotor rub, unwanted brake noise, and the constant pad drag issues that can frustrate riders on modern aero road bikes.

Why Choose the Lewis SLR?

• Extremely Lightweight Design: At just 68.5 g for the caliper body, the SLR is a serious upgrade for riders building lightweight road, climbing, and race bikes.
• Larger 21 mm Titanium Pistons: Oversized pistons improve braking power and lever consistency while titanium helps reduce heat transfer into the brake fluid.
