After reading this thread I want to jump in. I too have a hybrid, Giant--Sedona. regular peddles to boot. I want to be efficient with my riding and in this thought process am wondering if a move to clipless w.shoes or staying where I am is the right thing. I am preping for a century and am at a crossroads. I have fun and feel myself getting stronger doing what I am doing with what I have. As for shorts...I love mine. Wouldnt ride without them.
