It will generally help interval power, almost anything a couple hours or less. For the typical USA races it is generally beneficial. The kids that lifted improved a bunch reducing time on bike and increasing time in gym. USACycling coaches don't like that so much as they are trying to build multi-day endurance stage athletes and they tend to value road miles vs gym time. I think the gym time at the expense of *some* road time is worthwhile if you are a USA race type.
