The most popular road groupset worldwide is now 11 speed 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 be 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 (medium) options are available, with the latter needed for a 32T cassette. Shimano R317 mechanical discs are a no fuss brake, with adjustable pad clearance & offer fantastic braking performance in all weathers.
