I'm a new road biker, just 3 months into it. I'm adding to my 25 miles a week of running which I've been doing for many yeaars. I'm starting to ride about 50-100 miles a week, and will build upon that. But I'm still using the cage footing that came with my Trek 1000. Should I upgrade to clipless? And if so, what's appropriate for a newbie like me?
