Important: Select your bike make, model and rotor diameter carefully. The rotor diameter must match your brake bracket, and the mounting pattern must match the wheel hub.
What’s Included
- 1 EBG V2.1 rear floating brake rotor in the selected size and fitment
- 1 set of fitment-specific titanium mounting bolts
Not included: Brake caliper and caliper conversion bracket.
Why Upgrade?
Repeated hard braking, long descents and technical off-road riding can push standard bicycle-style rotors beyond their heat and rigidity limits. The EBG V2.1 combines a heat-treated braking ring with a floating aluminum carrier to improve thermal stability, maintain consistent pad contact and reduce the risk of distortion through repeated heat cycles.
Materials and Construction
- Braking ring: Heat-treated 420J2 stainless steel for strength, wear resistance and corrosion resistance.
- Rotor thickness: 3.5mm for increased rigidity and heat capacity.
- Floating carrier: CNC-machined 7075-T6 aluminum for high strength with lower rotational mass.
- Floating construction: Allows controlled thermal expansion between the braking ring and carrier to help reduce warping.
- Machined braking surfaces: Designed for stable pad contact and predictable braking response.
Compatibility Notice
Requires a Surron Ultra Bee rear caliper or another rear caliper compatible with a 3.5mm rotor. Standard stock e-bike calipers are not compatible.
