Following the well-received introductions of its Dura-Ace and Ultegra 11-speed series component and wheel lines, Shimano introduces its new mechanical 105 5800 series components that also deliver the most lauded features of the new premium 11-speed groups: ultra light action shifting andpowerful braking. Designed to inspire riders of all levels, the all-new 105 5800 component group brings top-level performance to the widest range of riders, giving advanced functions, smooth operation and comfortable ergonomics.
The new 105 has an 11-speed drivetrain and adopted some key features from Dura-Ace and Ultegra. 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 Shimanos philosophy of system engineering. All parts are individually designed to work together as one groupset.
To finish the 105 5800 group are updated PD-5800 carbon pedals. Using a durable stainless steel body plate and wide bearing placement, the PD-5800 pedals offer maximum power transfer and increased lifespan.
