Riding clipless on the road bike is WAY more second nature than riding clipless on a mountain bike. I'll start off by saying (knock on wood). I have only fell once while riding my road bike and that was a case of hitting some loose sand and going too slow. Started falling before I could even think about unclipping. But on the mountain bike..... well quite a few low speed falls. I even fell 2 times in the same place on an out and back ride. Thought I could make it through the sugar sand (Florida special) nope... got in the middle of it fell. Of course covered with sweat it just stuck to me. An hour later on the way back... I JUST KNEW I could make it through it this time.... NOPE.... Almost the same exact spot.. Another time was riding a trail with a friend and at the last second saw this BIG A$$ spider hanging down in front of me (never ride in front in Florida). I tried bailing before I hit the spider.... Didn't unclip fast enough.... down i went...... But didn't hit the spider so it was a success... LOL The friend I was riding with thought I was having some kind of fit....
