Ultegra FC-R8000 Crankset

Shimano's Ultegra FC-R8000 Crankset represents true trickle down from Shimano's flagship Dura-Ace group not only visually, but in the technological features that make both cranksets light, stiff, and shift with precision. The new, aggressively angular lines increase stiffness, providing excellent power transfer. The chainrings and bolts were also redesigned to provide better chainstay clearance for shorter rear end bikes or road disc bikes with wider dropout spacing.

Shimano has the technical expertise and manufacturing prowess to create industry-leading shifting and stiffness to weight for the rings and crank arms, respectively. The latter property is owed to Shimano's Hollowtech II arm construction, a heavily guarded secret.
