Close ratio gear combination for minimum shifting gap provides improved cadence while reducing pedal effort. HG-X chainring with patented spike pins gives smooth and fast gear shifts under load. Stiffness and strength increased with advanced design due to wider spaced bearings and oversized axle.
Although the crank arms and spider arms are noticeably bigger, which increases stiffness, the overall weight has dropped by 7g over the previous edition of Dura-Ace. Shimano has adapted the crankset to work with disc brake road bikes that generally have 135mm rear hub spacing and shorter chainstays without the need to increase Q-factor thanks to its wider chainring spacing. The Double version offered here comes in numerous gear combinations to best suit each individual riders needs. Please note: Bottom bracket is NOT included
This crankset features a gear range that provides the perfect pedalling performance for large wheel bikes. It's smaller chainrings give an efficient and silent performance, even when used on long-travel full-suspension bikes. Plus, this double crankset has a 2-Piece aluminium construction for the perfect balance of strength and low weight at an affordable price. Shimano HG-X Further evolution of shifting performance, a directional mountain bike specific 10-speed HG-X chain provides smoother shifting, lighter weight and greater overall performance. This directional chain features an outer chainring that's optimized for front shifting while the inner chainring is optimized for rear shifting.
This 10-speed double chainring features Shimano's Hyperglide and Dyna-Sys technologies. Remarkably stable and extremely efficient, the Shimano XT 10-Speed Double Chainring is an excellent upgrade or replacement component.
