Free Shipping: On all orders
Size: 203*2.3mm / 223mm*2.3mm /220mm*3.0mm / 223mm*3.0mm
Aperture: 54mm for Surron Light Bee Rear Wheel
Material: 420 stainless steel.
Laser cut and molded with high precision, low deformation and low induced stress.
The dense perforated design used in the HD rotor effectively increases the heat dissipation area of the rotors.
The 12-spoke support design, coupled with internal triangular reinforcement, increases the support strength at the fixed position of the rotor, reducing the likelihood of fastener loosening caused by rotor resonance.
The surface employs a multifaceted polishing process to ensure uniform smoothness and roughness of the rotor surface.
The edges are chamfered, and all cut surfaces are coated with electrophoretic paint. This not only prevents rust but also to some extent reduces the occurrence of injuries caused by contact with the sharp edges of the rotor, thereby enhancing the safety attributes of the rotor.
Multiple specifications, suitable for rear wheel of Surron Light bee.
Four sizes sit under this one LEWIS Heavy Duty rotor, so the real question is which thickness and diameter your Surron Light Bee rear wheel should run. Treat the thickness as the first decision, because your pads and caliper may settle it for you.
Deciding between 2.3mm and 3.0mm
A 3.0mm rotor carries more 420 stainless steel than a 2.3mm rotor of the same diameter, and more steel generally means more room to absorb heat at the cost of extra rotating mass. Your caliper and pad set still have the final say, so confirm what they accept before you pick the thicker option.
Diameter choices and caliper position
The 2.3mm pair comes in 203mm and 223mm, while the 3.0mm pair comes in 220mm and 223mm. Moving to a different diameter usually means changing where the caliper sits, so as a general rule check your bracket before ordering and see that the pads will land fully on the braking track.
Reading the 54mm bolt pattern
This rotor uses a 54mm mounting bolt hole distance for the Surron Light Bee rear wheel, which is sometimes called the aperture. Hold the rotor up to your hub before tightening anything, because a pattern that nearly lines up is still the wrong pattern.
- 203mm x 2.3mm and 223mm x 2.3mm for the thinner choice
- 220mm x 3.0mm and 223mm x 3.0mm for the thicker choice
- Laser cutting and integrated molding for low deformation
- Dense perforated track to add heat dissipation area
- 12-spoke support with internal triangular reinforcement
- Multifaceted polishing, chamfered edges and electrophoretic paint on cut surfaces
After fitting, spin the rear wheel and watch the gap on each side of the rotor. A clean, even pass through the caliper means the size and mount you chose are working together.
