  Product Description
Performance without compromise

Three key words have emerged as the theme for the DURA-ACE® system: Speed, Smooth and Strength. Speed and Smooth result in effortless shifting, improved braking operation, enhanced ergonomics and an attractive feeling and design. Strength is focused on the critical need for lightweight without sacrificing rigidity, durability or precision. "100% Power Transmission" is the goal pursued by the fusion of these three concepts. Ride Dura-Ace® to see why Lance has ridden to 7 Tour de France victories aboard Dura-Ace® components.

While the grade of materials and the surface treatment of the races may change between groups, one thing is constant. Shimano hubs exclusively use a cup and cone bearing system in all of its hubs. Cup-and-cone bearings offer greater strength than sealed cartridge bearings due to their ability to displace lateral and vertical loads more effectively for super smooth rotation in real world riding conditions. Cup-and-cone bearings also allow for easier maintenance, adjustability and serviceability.

Shimano Dura-Ace HB-7800 Rear Hub is a super lightweight, 10-speed compatible, smooth rolling, 32 Hole hub featuring Double Contact Sealing, Stainless Steel Balls, and user-friendly Dish Distance.
