Lewis LHT: The New Standard in Precision Braking

The Lewis LHT Axial Cylinder 4-Piston Brake is a masterclass in CNC engineering, designed for riders who demand more than just stopping power; they demand perfection. Built for the rigors of Trail, All-Mountain, and Enduro riding, the LHT combines massive power with an incredibly refined lever feel that puts you in total control of every corner.

Milled from a single block of 7075 T6 Aluminum, the caliper offers exceptional rigidity. This stiffness translates directly to the trail: when you pull the lever, there is zero flex, just immediate, modulated power.

Why the Lewis LHT Stands Out:

• Ultimate Tunability (3-Way Adjustment): Most brakes only offer reach adjustment. The LHT offers three adjustments which we call the "Lewis Trifecta": Lever Reach, Bite Point, and Lever Ratio. This rare feature allows you to tune the mechanical advantage of the lever to be either "Linear" (smooth modulation) or "Progressive" (snappy, on/off power).
  
  
• Hybrid Piston Technology: The caliper houses 4 x 17mm pistons made from a hybrid of Titanium piston and Ceramic insulator. The ceramic core insulates the fluid from heat, while the titanium shell provides unmatched durability.
  
  
• Titanium Hardware Standard: We don't cut corners. Premium Titanium bolts are used throughout the entire brake kit. This maximizes strength-to-weight efficiency, ensuring your hardware will never rust or corrode.
  
  
• Kevlar Braided Hoses: Say goodbye to flimsy stock hoses. The LHT comes pre-installed with steel/Kevlar braided hoses that prevent expansion under pressure, ensuring your brake feel stays solid even during panic stops.
  
  
• Maintenance Friendly: The advanced anti-leak oil system simplifies bleeding, and the brakes run on standard Mineral Oil, making them safe and easy to service in your home shop.

Mechanic's Note: Worried about finding replacement pads? The Lewis LHT is compatible with Hope V4 pads, meaning you can find replacement pads at almost any bike shop in the world.

Configuration & Setup:

These brakes are sold in the standard configuration:

• Left Lever: Front Brake (90cm Hose)
• Right Lever: Rear Brake (160cm Hose)

Note: Prefer your brakes "Moto" style (Right/Front, Left/Rear)? The levers are designed to be reversible. You can swap the hydraulic hoses easily to suit your riding preference.

Lewis LHP-U4: Ultimate 4-Piston Breaking Power

The Lewis LHP-U4 Axial Cylinder Brake is engineered for the most demanding mountain biking disciplines. Whether you are racing Downhill, charging Enduro stages, or tackling technical All-Mountain terrain, the LHP-U4 delivers consistent, fade-free power.

Machined from CNC 7075 T6 Aluminum, this brake system prioritizes rigidity and heat management. The massive 4-piston caliper features independent cooling fins and huge oil reserves, ensuring that your braking power stays consistent from the top of the mountain to the bottom.

Key Performance Features:

• Triple Adjustability: Just like its big brother (the LHT), the LHP-U4 features the "Lewis Trifecta" of adjustments. You can tune the Lever Reach, the Bite Point, and the Leverage Ratio. This allows you to toggle between a snappy, aggressive bite or a linear, modulated feel.
  
  
• Heat Management System: The caliper houses 4 x Stainless Steel Pistons equipped with special insulating layers. Combined with the machined cooling fins on the caliper body, this design isolates the hydraulic fluid from brake heat, preventing "pump up" or fade during intense braking.
  
  
• Rigid CNC Construction: The 7075 T6 Aluminum body is lightweight yet incredibly stiff, translating your finger input directly into stopping power without the flex found in cast brakes.
  
  
• Anti-Leak Technology: Features advanced seal designs to ensure air-tight performance and simplified bleeding maintenance.

Mechanic's Note (Pad Compatibility): The LHP-U4 caliper is typically compatible with Hope E4 brake pads. This means finding replacement pads, whether sintered or metallic, is easy at almost any bike shop.

Important: Installation & Fitment Guide

Caliper Clearance Warning: The LHP-U4 features a robust, oversized CNC-caliper body. On certain forks (specifically the Fox 36), standard flat adapters may cause clearance issues.

• We strongly recommend using the Lewis PM-PM+20-A Adapter.
  
  
• This "A" model is specifically shaped to provide the necessary clearance for the LHP caliper body.
  
  
• If you are using a 200mm rotor with a 180mm post mount fork (standard Fox 36 setup), the "A" adapter is the safest choice to ensure a rub-free installation. If you're running a 220mm rotor on a 180mm post mount fork, consider our 40mm Adapter, available here.

Configuration:

These brakes are sold in the standard configuration:

Lewis LH4: Premium CNC Braking Performance

The Lewis LH4 Axial Cylinder Brake brings boutique-level CNC quality to the trail at an accessible price point. Engineered for Downhill, Enduro, and All-Mountain riding, the LH4 strikes the perfect balance between raw stopping power and refined modulation.

Constructed from CNC-machined 7075 T6 Aluminum, the LH4 is significantly stiffer than standard cast brakes. This rigidity ensures that every millimeter of lever pull translates directly into braking force, giving you confidence on the steepest descents.

Key Features:

• Dual-Diameter Piston Technology: The caliper utilizes an asymmetric 4-piston layout (2 x 14mm and 2 x 17mm). The smaller pistons engage slightly earlier to ensure smooth initial modulation, while the larger pistons provide the raw clamping force required for maximum stopping power.
  
  
• Tool-Free Dual Adjustment: Fine-tune your cockpit in seconds. The LH4 features patented external dials for Lever Reach (Tool-free) and Bite Point (Hex key needed, thumb tool included) adjustment, allowing you to customize exactly where the lever sits and where the power kicks in.
  
  
• Ultra-Smooth Lever Feel: Unlike budget brakes that use bushings, the LH4 lever pivots on precision sealed bearings. This results in a frictionless, feather-light lever action that reduces hand fatigue on long runs.
  
  
• Robust Build Quality: Features split clamps for easy installation and Kevlar-reinforced hoses to prevent hydraulic expansion and loss of power under heavy load.

Mechanic's Note (Pad Compatibility): The Lewis LH4 is designed to use Hope Tech 3 E4 brake pads. This large pad shape provides excellent heat management and modulation.

Configuration:

These brakes are sold in the standard configuration:

• Left Lever: Front Brake
• Right Lever: Rear Brake

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.

The Lewis AE is designed for riders who want a strong, immediate brake feel with premium materials and serious stopping power. Built around a one-piece monoblock CNC caliper and an axial master cylinder, the AE delivers a direct, solid lever feel with the kind of control and consistency aggressive riders look for in trail, enduro, and downhill braking.

Lewis developed the AE for riders who prefer a firmer, more substantial lever character. Compared with a lighter, more progressive brake feel, the AE gives stronger feedback at the lever and a more immediate bite point. For riders who like a more decisive braking response, the AE is built to feel powerful, planted, and confidence-inspiring on steep terrain.

Why the Lewis AE Stands Out

• Monoblock CNC Caliper: The AE uses a one-piece monoblock 7075-T6 aluminum caliper instead of a more common two-piece design. This helps reduce caliper flex and supports more direct, consistent braking power.
• Axial Master Cylinder: The axial cylinder layout creates a crisp, responsive engagement point with a firm lever feel that many aggressive riders prefer.
• 4-Bearing Lever Pivot: The lever rides on 4 sealed cartridge bearings rather than basic bushings, helping improve smoothness, reduce lever play, and support long-term durability.
• Asymmetric 4-Piston Layout: The caliper uses 2 x 14 mm and 2 x 17 mm stainless steel pistons to balance initial control with strong overall stopping power.
• Premium CNC Finish: Precision-machined construction gives the AE a higher-end look and feel than many brakes in the same category.
• Mineral Oil System: Designed around mineral oil operation for riders and mechanics who prefer that brake fluid platform.

Ride Feel & Performance

• Firm, substantial lever feel

Important Fitment Information

These rotors use specific bolt circle diameters (BCD). That means only certain versions will fit specific bikes. Check your hub and rotor mounting pattern carefully before ordering.

Warning: These rotors are not compatible with Talaria rear rotor applications. For Talaria, this listing is front rotor only. For Sur-Ron, you must choose the correct BCD-specific rotor version for your bike.

What Is a Floating Rotor?

A floating brake rotor uses a two-piece design where the outer braking ring is attached to the inner carrier with rivets or floating hardware instead of being rigidly fixed in one piece. This allows the braking surface to move slightly as it heats and cools.

Under braking, the outer steel ring expands as temperatures rise. On a one-piece rotor, that heat expansion can contribute to warping or distortion. On a floating rotor, the braking ring can expand more independently from the carrier, helping the rotor stay flatter and more consistent under heat. The result is improved braking stability, better pad contact, and reduced likelihood of heat-related rotor deformation.

Why Choose a Floating Rotor?

• Better Heat Management: Helps the braking surface expand under heat with less distortion.
• Reduced Warping Risk: Floating construction helps reduce the chance of rotor deformation during heavy braking.
• More Consistent Pad Contact: A flatter rotor under heat helps maintain more even braking feel.
• Improved Fade Resistance: Better heat handling can support more stable braking on long descents.
• Lighter Two-Piece Design: Aluminum carrier reduces weight while the steel braking ring maintains durability.
