Last week, after a couple years of hybrid riding, I made the move to a road bike. For the first time I'm also using clipless pedals. After my first ride, and two subsequent rides, I have sore leg muscles - but it's a different soreness than I've experienced in the past - say from riding the hybrid longer distances than usual. Is it the different riding position, the effect of the clipless pedals, or a combination of the two? I'm just curious . . .
