The most popular road groupset worldwide is now 11 speed & has enhanced braking power. The new 5800 series 105 features technology that has trickled down from Shimano's high-level Dura-Ace & Ultegra groups. 105 now gains the light yet positive shift action found in Dura-Ace & Ultegra levers; there's also a new compact shape that's borrowed from the levers of Shimano's more expensive groups. The lever can adjusted to accommodate different hand sizes via a 10mm screw-type reach adjustment. The new 5800 front derailleur has a longer link arm & a new spring mechanism when compared with the last generation component. Shimano has included a new spring mechanism & cable pitch in the latest 105 rear derailleur, said to provide robust adjustability. Both SS (short) & GS (long) options will be available, with the latter being compatible with a 32t cassette. 105 5800 Brakes have taken a step up to a new symmetrical dual pivot caliper design, with a higher arch allowing clearance for up to 28mm-wide tyre. The result is a claimed 10% increase in power. ...
