Cycling is not a full-body activity, so you need to do something that exercises those muscles (and all other parts of your musculoskeletal system, i.e. connective tissues...) and weight training can fill in those gaps. Also, it's a total myth that if you cycle, you don't need to do lower-body exercises using weights -- cycling does not exercise all parts of the legs equally and can lead to muscle imbalances over time.
