The 4-arm awesomeness that's revolutionized Shimano's Dura-Ace and Ultegra cranksets has trickled down to the 105 level with the FC-5800-S 11-speed crankset. While shedding grams and increasing stiffness over the previous, 5-arm 105 cranks, the 4-arm design features the same bolt pattern for compact and standard-sized road chainrings so the versatility of the crankset is maximized. No need for a new crankset if you seek to change gearing -- simply swap out the chainrings. That's a win-win situation in our book. And for those who prefer a traditional color aesthetic for their components, this version of the Shimano 105 5800 crankset features a silver finish.
  • 4-arm design is super-stiff plus lighter than traditional 5-arm cranksets
  • Cold forged aluminum construction delivers remarkable strength
  • Hyperdrive SG-X chainrings provides smooth shifting
  • Reinforced construction around chainring area ensures improved stiffness to weight ratio
  • Same bolt circle diameter for compact and traditional-sized double chainrings means one crankarm fits all chainring sizes
  • 50/34t compact chainrings provide low climbing gears without sacrificing much in top-end speed
  • For Shimano 11-speed drivetrains
  • Silver finish
