The new 11-speed Shimano 105 group is a huge leap forward from the previous 10-speed family, narrowing the gap to its higher-cost siblings Ultegra and Dura-Ace down to a mere sliver. The 105 FC-5800 11-Speed Crankset gives you oodles of performance and gets the drivetrain rolling without draining your bank account. This crankset is lighter and stiffer than previous models, featuring a new, eye-catching 4-bolt spider and chainring configuration with carbide construction to increase shifting precision and power transfer. Pairing all that function with its overall sleek design means you'll get down the road fast and look good while you're at it.
- Hollowtech II design has an optimum balance of lightweight and stiffness for better power transfer and acceleration
- New gear dimensions enhance overall performance
- Improved gearing for less chain touch in small/small combination
- Reinforced construction around the chainring area further improves stiffness-to-weight ratio
- Hyperdrive SG-X chainrings for super smooth front shifting and special tooth profiles, pick-up spikes and ramps help make the front derailleur shifts quiet, easy and trouble-free
