I don't think this is right. Though I don't have problems with these muscles cramping, I definitely feel strain in them during cycling. For me, I feel them when I am trying to turn big gears hard. That doesn't mean that I'm not using them other times, it's just that they feel strained under those conditions. I have once or twice overstrained them (not quite sprained), such that they were sore for a few days on one side or the other.
