PowerSet: Loads supported by the bearings in the bottom bracket are transmitted from the spindle through the balls. In normal cartridge bearings, the lower balls are the ones that support the entire load. Our patented POWER SET® system ensures all balls support equal loads. Thus, guaranteeing a smooth pedalling and a greater durability of bottom bracket bearings.
Angular contact ball bearings: support both axial and radial loads. These bearing types cannot be separated; therefore, they are mounted in pairs. In a standard single row radial ball bearing, only 3 or 4 balls make contact when pedalling. But with our patented preload system, all balls are engaged, spreading force over a larger surface, decreasing friction, and minimising wear.
FullySealed: Every dust particle or water droplet is a potential cause of bearing noise or wear. That is why all our bottom brackets are fitted with up to five O-rings to keep dust, water, mud and moisture out of the bottom bracket.
Axial Seals:
All our bearings are fitted with not one but TWO seals to protect against dust and moisture ingress. This section is crucial for maximum durability and performance of the bottom bracket.
7075-T6 aluminium: Aerospace quality and precision in one of the most capable aluminiums. Moreover, we have developed a particularly scratch-resistant matt anodising with a finish that would be worthy of any art gallery.
T6 heat treatment: For most aluminium alloys: 6061, 6063 and 7075, the best heat treatment is T6. The T6 heat treatment delivers increased hardness as well as other mechanical properties such as normalisation of its grain structure. This guarantees that all our aluminium products will perform perfectly throughout their service life.
High precision CNC Machined: All our products are manufactured with the help of the best CNC machines on the market providing incredible precision in complex geometries. This is critical to achieve minimal deviations in the concentricity of our DualCupTech™ and its tolerances across all surfaces.
