Lewis X-Power 200mm 2.3mm Disc Brake Floating Rotor

These rotors have a 44mm BCD (Bolt circle diameter). This means they WON'T work for your Sur-ron or Talaria rear brake rotor, only the front rotor!

The Lewis X-Power Floating Rotor is purpose-built for riders who demand reliable, fade-resistant braking on long descents, heavy e-MTBs, and aggressive trail or enduro bikes. Featuring a CNC-machined 420 stainless-steel braking track mated to a precision CNC-machined aluminum carrier, this rotor delivers powerful stopping force with reduced weight. The floating design uses riveted construction to allow controlled movement between the braking surface and carrier, helping the rotor handle extreme heat without warping or vibration.

What is a floating rotor?

A floating rotor is a type of bicycle or motorcycle disc brake rotor where the braking surface (the outer stainless steel ring) is attached to the carrier or spider (usually aluminum) using rivets or pins. The braking ring is not rigidly fixed to the carrier; instead, it can move slightly in a radial or axial direction (side to side or expand/contract). This design is why it’s called “floating.”

How does it work?

• Under braking, the steel braking surface heats up and expands. A one-piece (solid) rotor can warp or deform because there’s nowhere for that expansion to go.

• With a floating rotor, the outer braking ring can freely expand relative to the carrier because it is mounted on floating rivets. This reduces the chance of warping and helps maintain consistent braking performance, even under high temperatures.

Why use a floating rotor?

✅ Better heat management — allows the braking surface to expand without distorting
✅ Reduced warping — prevents the “dish” or “potato chip” effect of a solid rotor
✅ Lighter weight — the carrier can be made of aluminum to save weight, while the braking ring stays steel for durability
✅ Consistent braking — since it stays flatter under heat, you get more even pad contact

In short, floating rotors are a clever solution to deal with heat, reduce brake fade, and maintain consistent braking power.

With a 2.3 mm thickness and large diameter options (200mm and 220mm), the X-Power rotor offers improved heat capacity and greater brake torque for bikes that push the limits. The floating rivet system ensures consistent pad contact and reduces the risk of rotor fade on steep, sustained descents. Whether you’re charging bike park laps, tackling technical mountain trails, or managing the extra load of an e-bike, the X-Power rotor gives you confidence-inspiring braking performance that holds up under pressure.

Designed for compatibility with any standard 44mm BCD 6-bolt hub, these are only compatible with the front brake if you plan to use them on a Sur-ron or Talaria. installation is simple, and performance gains are immediate. The combination of a stainless-steel braking track and lightweight carrier strikes the ideal balance of durability and weight savings. If you’re looking for a rotor that brings together precision engineering, top-tier materials, and race-ready braking power, the Lewis X-Power Floating Rotor is ready to take your braking to the next level.
