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.

5800 Crankset Features:

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.

  • 105 FC-5800 Chainset 53.39t or 50.34t
  • Crank Arm Length: 172.5mm
  • HOLLOWTECH II design - Optimum balance of lightweight and stiffness
  • New gear dimension for great improvements
  • Improved gear for less chain touch in small/ small combination
  • Hyperdrive SG-X-chainrings
  • DUAL-SIS-compatible
  • Includes Bottom Bracket

Dual Control Shifters Set STI 105 ST-5800 Features:

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.

  • Powerful and controllable braking system

105 Rear Derailleur RD-5800 SS Features:

Shimano has included a new spring mechanism and cable pitch in the new 105 rear derailleur in order to provide robust adjustability.

  • Short Cage

105 Front Derailleur FD-5800 Braze On:

The new 105 front derailleur has a longer link arm and a new spring mechanism compared with the last generation component.

  • Braze On

105 Brakes Set BR-5800:

The new 105 brakes feature a new symmetrical dual pivot calliper design, with a higher arch allowing clearance for up to a 28mm wide tyre. This results in a 10% increase in power.

105 Cassette CS-5800:

The new 105 11 Speed Cassette uses close ratios that Shimano say optimise rhythm and cadence control.

  • 11.28t

CN-HG600 11-Speed Chain:

The new CN-HG600 11-Speed Chain uses Shimano’s low friction surface treatment known as SIL-TEC. The new chain’s PTFE surface coating reduces friction whilst boosting durability. The technology first debuted on Shimano’s flagship Dura-Ace 9000 Chain a couple of years ago.

  • 116 Links

Please note that this groupset does not come supplied with outer cables.
