This racing season I am lucky enough to be riding and racing on the excellent Specialized Tarmac SL4 Pro complete with the new cutting edge Shimano Ultegra Ui2 electronic groupset. After riding and racing the bike over the past month in various disciplines including 6hr training rides, 1hr Crits, hilly road races of 70+ miles and a recent hillclimb (where I got my 1st win of the season on this machine) I thought it would be a good time to share my experiences of riding the SL4.
