|Description||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 50/34t (Bottom Bracket Included)
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
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 Features:
Shimano has included a new spring mechanism and cable pitch in the new 105 rear derailleur in order to provide robust adjustability.
105 Front Derailleur FD-5800:
The new 105 front derailleur has a longer link arm and a new spring mechanism compared with the last generation component.
105 Brakes Set BR-5800:
The new 105 brakes feature a new symmetrical dual pivot caliper 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.
KMC 11 Speed X11-93:
A high performing and extremely durable, half nickel plated 11 speed chain. The X-Bridge technology is specially designed to enable fast, smooth and precise shifts thanks to the shaped outer plates. Compatible with all 11 speed road/MTB systems.
