Lewis X-Power Floating Rotor

High-heat braking performance for aggressive MTB, e-MTB, Sur-Ron, and select Talaria front brake applications.

The Lewis X-Power Floating Rotor is built for riders who need stronger, more consistent braking on long descents, heavier bikes, and high-load riding conditions. Designed with a CNC-machined 420 stainless steel braking track and a CNC-machined aluminum carrier, this rotor is engineered to deliver excellent stopping power while helping reduce weight compared with a fully steel design. Its floating rotor construction allows the braking ring to expand more freely under heat, helping reduce distortion, maintain flatter rotor performance, and preserve braking consistency when the system is pushed hard.

With a 2.3 mm thickness and large-diameter options, the X-Power rotor is especially well suited for riders looking for more heat capacity, stronger brake torque, and better durability under repeated heavy braking. Whether you are riding aggressive trail, enduro, bike park, downhill, or e-bike terrain, this rotor is designed to provide more confidence when speed, heat, and bike weight increase.

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.

Lewis Bike 6-Bolt Brake Rotor

Durable 420 stainless steel braking performance for MTB, e-bike, and select Sur-Ron front rotor applications.

The Lewis Bike Rotor is built for riders who want dependable braking performance, strong heat management, and long-term durability in demanding riding conditions. Made from 420 stainless steel, this rotor is designed to maintain strength under repeated braking loads while delivering consistent stopping power for trail, enduro, and heavier bike applications. Its precision laser-cut and molded construction helps preserve rotor shape over time, while the vented pattern is engineered to support heat dissipation during sustained braking.

A reinforced 12-spoke structure with internal triangular support features is designed to improve rotor stability and help reduce vibration under load. Combined with a smooth multi-stage polished braking surface, the rotor is built to provide more consistent pad contact, reliable braking feel, and improved long-term performance. Chamfered edges and a protective electrophoretic coating further improve finish quality while helping resist corrosion in harsh riding environments.

Important Fitment Warning

These rotors will not work with Talaria rear brake rotor applications. For Talaria, this rotor is front only. If you have a Sur-Ron, you must choose the correct BCD-specific rotor configuration before ordering.

Fitment Summary: Standard 44 mm BCD 6-bolt rotors fit typical MTB front and rear hubs, but Sur-Ron rear and Talaria rear use different rear BCD patterns. This rotor is only suitable for the front brake on Sur-Ron and Talaria unless you are purchasing a specifically matched non-standard rear version.

Key Features & Benefits

• 420 Stainless Steel Construction: Provides strong wear resistance, reliable braking strength, and durability for aggressive riding.
• Laser-Cut and Molded Design: Precision shaping helps the rotor maintain its form and braking consistency over time.
