We celebrate 50 years of the Shimano DuraAce, tracing the history of the groupset since its launch in 1973. Si rides Sean Yates’ 1984 7Eleven team bike with Shimano Indexed Shifting (SIS), a Lance Armstrongera Trek, Mark Cavendish’s 2011 Tour de France SWorks McLaren Venge with electronic Di2 shifting, as well as his own 12speed Pinarello F9.
