Shimano’s Ultegra components have long been counted on by riders for a mixture of efficient performance and great value. This Ultegra crankset has a technological trickledown from the more expensive flagship Dura-Ace piece. Aggressively angled lines help with power transfer while the Hollow Tech technology keeps things light. An asymmetric spider can accommodate the redesigned chainrings and bolts which are included in the redesign, helping with better chainstay clearance on some bikes. The tooth profile of this crank has also been altered to improve shifting efficiency and chain retention. If you are looking for an economical crankset with excellent power transfer, light weight, and reliable shifting, this Ultegra crankset is a great component for you.
