Performance, value, durability - for once you can have all three; quite simply a brilliant groupset
The Shimano 105 5800 groupset has been revamped for 2014/15. Now in 11 speed, these components draw down technology from the Shimano Dura-Ace and Ultegra groupsets.
The main new features are an 11-speed drivetrain that shifts more precise and lighter than ever, improved brake power and better control of the bike.
Shimano's new 105 gives the widest range of road riders the opportunity to ride a groupset that is inspired by professional riders. Whether it is for everyday riding or longer rides & climbs in the weekend.
The 105 has that same light action and defined click engagement like Dura-Ace and Ultegra. Partly because of the polymer coated cables and partly because of the redesigned derailleurs and shift levers. This clearly shows Shimano's philosophy of system engineering. All parts are individually designed to work together as one groupset. The shift levers have a compact grip which provides more comfort and control during a ride. The lever can be customized for different hand sizes with a 10mm screw type reach adjust.
The iconic four arm crank trickled down from Dura-Ace to the new 105 and gives the best power transfer and balance between stiffness and lightweight. It also has one bolt circle diameter for compact and traditional double chainsets which means one crankarm fits all chainring size.
Compared to the previous 105 groupset (5700) Shimano made the brake system more efficient and increased brake power with 10%. This is mainly due to the new symmetrical dual-pivot brake caliper.
