Shimano Ultegra

Ultegra R8000 series, a direct trickle down from Shimano's pinnacle Dura-Ace groupset, is pro-proven and designed for all-day riding comfort. Ride longer with superior ergonomics, advanced disc brake control in all conditions, and epic battery life.

Hollowtech II

Balancing stiffness and power transfer against overall component weight is a chief concern for any crankarm design. Shimano's Hollowtech II technology integrates the bottom bracket axle with the right crankarm for more stiffness and weight savings to achieve a high-dimensional balance. Its 24mm diameter, outboard bottom bracket bearing system provides better weight distribution and more pedaling stability, allowing for more efficient power transfer.
