Spanish brakes specialist Galfer has introduced a new oversized Wave fixed brake disc for electric bikes and 29 inch wheels that need increased stopping power.
Galfer says it will improve the brake cooling and performance on most electric bikes – notoriously poorly equipped when it comes to brakes, one of several basic oversights made by most e-bike manufacturers looking for a lowest possible on-sale price.
Increasing the outer diameter and thickness allows the brake system to absorb the increased weight of an e-bike (which ironically are 10-15 kg heavier than an equivalent conventional motorcycle) as well as the increasing speed and inertia caused by the electric traction motor.
Used with Galfer Bike semi-metallic brake pads, the oversized disc is also said to improve braking efficiency and overcome some of the technological challenges posed by electric bicycles.
For DH bicycles, the new DB007W is designed for bikes with bigger wheels (29”), which reach greater speeds, as well as for use in steep circuits or with extreme heat. The disc can also be used in 27.5” and 26” wheels.
For safety reasons, Galfer Bike only recommends using the new oversized 223 mm discs on radial mounts (PM, Postmount) and not on axial mounts (IS, International Standard), and in frames capable of withstanding the extra stress caused by these kinds of oversized discs. The new disc can be mounted in original sized forks and frames without 180 mm or 203 mm adapters by using new brackets that Galfer Bike will include in its 2019 catalogue.
Also seen here, Galfer Bike is introducing a new semi-metallic brake pad compound for electric bikes. The new G1652 compound, violet coloured, stands out for its resistance to high temperatures, braking power, durability and quiet braking.
