• Characteristics
• PowerSet Technology. By taking into consideration the behaviour of a bearing when it is under load we have designed a bottom bracket that reduces power loss by up to 20%.
• Preloaded System. All the balls come into contact with the bearing
• distributing the force over a larger surface area. By doing this
• we reduce friction and minimise wear.
• Angular Ball Contact Bearings. They support both axial and radial loads.
• Unibody design. Ensures the parallelism and concentricity of the bottom bracket.
• Fully sealed. Axial seals on bearings and fully sealed on all surfaces
• to avoid water or dust.
• All this technology combined allow to get the most out of the rider's power on each pedal stroke
• optimising your performance and making you go faster.
