I'm going to start riding with Look Keo Classics and Sidi Genius 5 Pros as my first clipless setup. I always have a bag with me though so I figure I'll just change shoes when I get to work/the library/wherever. Does anyone have any beginner's tips? I sort of want to avoid 0 km/h falls, as it's dangerous for both me and my bike... D: Is it safe to start with the tension dialed down a lot so it's easy to unclip? Or is that less safe than it sounds?
