The updated Shimano 11-speed compact crankset features a new four-arm HollowTech II design similar to that of the current Ultegra and Dura-Ace.
Lighter and stiffer than earlier models, this Shimano 105 5800 11-Speed Compact Chainset has a reinforced construction around the chainring area to further improve the stiffness to weight ratio. The chainset uses the same bolt circle diameter for compact and traditional double chainsets, which means one crankarm fits all chainring sizes.
