Description	The 2017 Shimano Dura Ace Di2 9150 Groupset is a top-of-the-line electronic-shift road group. The latest instance of this high-performance championship group has some refinements and some larger changes; among the latter category are the introduction of a power meter and the incorporation of the off-road Shadow rear derailleur mechanism into the RD-R9150 mech. Among the more modest changes, a new look: the lines are sharper across the board, from the new, wider brake calipers, capable of surrounding a 28mm tire, to the front derailleur. The combination levers have also been refreshed; the lever itself is a bit smoother, and the hoods are textured. A very good road group.	The 2016 SRAM eTAP group is an electronic-shift parts group. The first from SRAM, eTAP starts with the top-end Red mechanical road group, adding versatile electronic shifting via traditional combination shift/brake levers or the novel Blip, locatable anywhere, complemented nicely with the S-9xx aero brake levers, an excellent pairing for time trials. Options for positioning include direct mounting, bar-end mounting, and a strap-on mount for 31.8mm bar diameters. The BlipBox communication hub mounts easily, compatible with Garmin mounts; when using paddle shifters the BlipBox is not required, Blip ports present for both left and right levers. Rechargeable batteries for the derailleurs are interchangeable; standard disposable CR2032 batteries are used for the shifters. An indicator light informs the rider when battery charge is low. Charge span is estimated to be greater than 1000km on the road. An excellent electronic-shift road group.	The 2016 Campagnolo Super Record EPS group is Campy's top-of-the-line electronic shift road group. With every component designed for high performance, you'll get lightning-fast, clean shifts, precise braking control, and exceptional power transfer. Super Record incorporates titanium and carbon fibre to offer an amazingly lightweight and durable road group. Electronic components include a multiple-mount battery, securable within seatpost or downtube, and a low-profile controller fitting snugly and conveniently out-of-the-way by the stem. In the very unlikely event of system failure the gear can be selected by hand, using Campagnolo's custom UnLock system. Mechanical componentry includes the ace Super Record skeleton brakeset and hollow-core, titanium-axled crankset. An exceptional electronic-shift road group.
