Shimano 105 5800 11-speed Groupset

Smooth, Round and Natural' - the ethos behind Shimano 105 components. The 105 groupset makes 'pro-level' technology more accessible to part time racers and fitness enthusiasts.The all new 105 5800 Groupset now has an 11 Speed Drivetrain , with all components gaining trickle down technology from Shimano’s existing Ultegra and Dura-Ace groups.
Specification
  • 105 now gains the light and responsive shift action found in Dura-Ace and Ultegra Levers, with a new compact shape that’s been borrowed from the levers of Shimano’s more expensive groupsets. The lever can also be adjusted to accommodate different hand sizes.
  • The new 5800 Crankset features a new four-arm Hollowtech II design similar to that of the current Ultegra and Dura-Ace. The new chainset is stiffer and lighter than the five-arm design it replaces and Shimano have reinforced construction around the chainring area to further improve the stiffness to weight ratio.
  • The new 105 11 Speed Cassette uses close ratios that Shimano say optimise rhythm and cadence control - available in a range of sizes
  • The new CN-HG600 11-Speed Chain uses Shimano’s low friction surface treatment known as SIL-TEC.
