Lewis X-Power 2mm Floating Rotors
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.
Warning: These rotors will not work with a Talaria E-Moto rear brake rotor, only the front rotor! If you have a Surron, you must pick the right rotor BCD configuration!
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
