The most noteworthy detail of Campagnolo's 11-Speed Carbon Bar End Shifters is that they use a return-to-center function. The difference between this set and the alloy version is simply a matter of material. The carbon fiber gives these an aesthetic to match your Super-Record, Record, and Chorus groups. Plus you'll save 11 grams over the alloy versions.Like their Ergopower levers, the 11-Speed Bar End Shift Levers can make sweeping gear changes. This allows you to shift up to three gears at a time, up or down the cassette. Of course, you can also make single gear changes. The front shifter shares the same basic function as its Ergopower counterpart. It features indexed movement that allows you to easily and accurately trim the front derailleur to accommodate any front/rear gear configuration. And after each shift, the levers return to their pre-set center position.These Campagnolo 11-Speed Carbon Bar End Shifters have a compression plug that allows their installation in any modern time trial or clip-on aero handlebars. Just remember when you install them, our photo shows these as you'd see them while on the bike. They come with a Campagnolo stainless steel inner shift cable and housing set.
