SHIMANO WH-RS770-C30-TL | ULTEGRA Grade Wheels That Balance Agile Response and Easy Handling

Light acceleration and natural handling. Road wheels that make every ride more enjoyable.

The SHIMANO WH-RS770-C30-TL is an ULTEGRA grade road wheel that offers a balanced improvement in "riding quality," with a light response the moment you pedal, stability during cruising, and a natural ride that reduces fatigue even on long distances.

The 28mm-height rim, featuring a carbon laminate construction, achieves both lightness and rigidity. The moderate rim height setting makes it easy to handle in a wide range of situations, from flat roads to climbs and long rides.

Furthermore, its road tubeless compatibility reduces rolling resistance and improves comfort. It's a highly satisfying upgrade from stock wheels and comes highly recommended for those who "want to ride more comfortably."

This model offers a noticeably "lighter ride" sensation when upgraded from stock wheels.

The feeling of initial acceleration and speed maintenance is particularly natural, and it's not overly stiff, making it well-suited for long rides. Thanks to the exquisite balance of the 28mm height, it offers a consistent and easy-to-handle experience across flat terrain, climbs, and crosswinds.

Additionally, the quiet rotation feel of the Silence FH is a characteristic sign of SHIMANO's quality. It's a wheel that can be easily recommended not only for racing but also for those who want to make their daily rides more comfortable.
