Hey Guys! This is my dilemma. My LBS is unloading there 2014 bikes to make room for the 2015's. My guy i deal directly has given me these options. Both bikes are identical except for the groupset.I can go 105 with an FSA SLK compact crank,or full ULTEGRA. Price difference is 488.58. Any and all input is GREATLY APPRECIATED! Thanks!
