105 Hydraulic Disc Groupset
The most popular road groupset worldwide is now 11 speed and has hydraulic braking power
The new 5800 series 105 features technology that has trickled down from Shimano's high-level Dura-Ace and Ultegra groups. The new 5800 front derailleur has a longer link arm and a new spring mechanism when compared with the last generation component. Shimano has included a new spring mechanism and cable pitch in the latest 105 rear derailleur, said to provide robust adjustability.
The fully hydraulic braking built into the sleek shifter body provides powerful, controllable and consistent stopping power with much less effort when compared to standard rim, or cable operated discs.
Both SS (short) and GS (medium) options are available, with the latter needed for a 32T cassette.
