Now with a 4-arm Hollowtech II design passed down from Ultegra and Dura-Ace, the Shimano 105 FC-5800 50/34T 11-Speed Crankset achieves the perfect balance of lightweight rigidity and power transfer. It's lighter and more unyielding than its previous 5-arm design and features reinforced construction around the chainring area for an even better stiffness-to-weight ratio. Asymmetric 4-bolt pattern is the same for both compact and standard chainrings, so one crankarm fits all chainrings sizes. The chainrings are also interchangeable with Ultegra and Dura-Ace for even more versatility.
