Shimano Dura-Ace R9270 Groupset

Including Shimano's finest components, the Dura-Ace R9270 Groupset perfectly suits the flashiest bike builds and the most discerning road riders. The electronic Di2 gears utilise a semi-wired configuration that sees the wireless STI levers send rapid gear change signals via a deft touch of a button to the derailleurs. The rear derailleur, front derailleur and internal battery are hard-wired, communicating with each other to ensure fast and accurate gear changes. This semi-wired format ensures excellent derailleur run times between charges and provides a stronger gearshift action for snappier gear changes. The gear system can be hooked up to the new E-TUBE smartphone app so that the rider can completely customise the gear change behaviour in line with personal preferences and the terrain.

The 12-speed cassette closes the jumps between sprockets to enable a more consistent cadence and increases the gear range for when tackling challenging climbs. The sprockets of the cassette are shaped via Shimano's Hyperglide+ format that, in partnership with the more positive derailleur action, grants silky smooth actuation. Complementing the cassette, the Hollowglide II aluminium chainset is extra-light but exceedingly stiff to guarantee efficient power transfer from the rider to the drivetrain.

Refined lever hood ergonomics afford more handholds, especially when adopting an aggressive, aerodynamic riding position, and the carbon brake lever with Servo Wave technology markedly heightens control of the hydraulic disc brakes. These levers are linked to one-piece calipers with 10% extra pad-to-rotor clearance to quieten operation in bad weather or after lengthy descents.
