Shimano Wheel Technology

Please contact skypartner@rapha.cc to place your order.

SHIMANO's ACCELERATION wheel concept follows the original DURA-ACE guiding principle of delivering the most efficient drivetrain system for performance road racing and riding. The new, ultra-lightweight rim designs results in lower inertia while maintaining stiffness and rigidity for acceleration and speed.

Precision: bearing durability in all conditions
For increased performance in real-world conditions, SHIMANO exclusively uses angular contact bearings, which better enable the hub to support lateral loading of the wheel.

At the DURA-ACE level, these high quality ball bearings and races, already ground to amazing precision are further laser-measured and matched.

Strength: Off-center rims mean more rear wheel strength
Off-center rim technology decreases spoke angle on cassette side, enabling more even spoke tension and a stronger wheel.

Quality, durability and lightweight. There's no question that SHIMANO builds wheels for the most performance-minded customers.

All DURA-ACE level wheels come with a 3-year warranty.
