SHIMANO DURA-ACE Di2 ST-9070 Shifter Set Pair Electronic 2 x 11s Road Bike NEW

SHIMANODi2 DURA-ACE STI SHIFTERS - PAIRDura-Ace Di2 has become renowned as "the" electronic shifting system totrust. And while it neared perfection, leave it to Shimano to improveupon it even more with the advent of the Dura-Ace Di2 9070 11-Speed STIShifters. First and foremost, you'll notice that the new Di2 features 11 speeds,which is quickly becoming the number to hit. But beyond that, Shimanolooked at the aesthetics and ergonomics of the levers to create touchpoints that enhance your riding experience. The shape of the levers hasbeen given even more of an outward curve while also growing in length.This allows for a better interaction with the levers, whether you're onthe hoods or in the drops. Speaking of the hoods, they are made from adual-compound rubber composite with a perforated design, but are nowsmaller and slimmer in shape. Conversely, the shift paddles have beenwidened for a better interface in the heat of the moment. Shimano stilladds in 10mm of reach adjustment.Beyond the aesthetics is the shifting performance. It is here thatShimano's Rider-Tuned philosophy takes shape. For example, with the Di29070, you're able to select one of five different rear derailleurshifting speeds. More impressive is that the 9070 is now capable ofperforming shifts up to 28 teeth on the cassette. To enhance shifting,a more minimal single-wire E-Tube connection is used. This also makesfor more options for the inclusion of satellite shifting systems.DESCRIPTION:Manufacturer: SHIMANOModel: DURA-ACE Di2Model #: ST-9070Compatible components: SHIMANO DURA-ACE 9070 and 7970Type: ElectronicUse with: E-tube electric cables (not included)SLR brake cable set: not included (comes as shown)Speeds: 2 x 11Hood material: Dual-compound rubberLever blade material: Carbon fiberColor: BlackWeight: 237g/prCondition: New - in OEM packaging
