  1. Warning!!!
    Clipless pedals are very dangerous.
    I’ve been riding bicycles continuously since I was 5. Have even commuted to work year-round in suburb north of NYC, Had been using Shimno clipless pedals for about 10 years and had several occasions when I couldn’t release from the pedal and dumped over. The last time, at age 58, caused my right hip to fracture. I needed 2 surgeries and 6 months of rehab. After the accident I found out about two other cyclists who suffered hip fractures because they couldn’t release from their pedals.
    Needless to say I took them off my Trek and will never use them again.
    The Pain was not worth the gain.

    • There is no doubt that clipless pedals can be difficult to get out in certain situations. For the longest time, I actually left the test platform clipped into one side of the pedal. This allowed me to have a stable platform to rest my foot in certain circumstances where I did not feel comfortable with my foot clipped in. Usually this was rock gardens. Not all pedals come with a test platform however but this worked for me. Additionally, I adjusted the tension to about the easiest setting and I always clean both the pedal and the shoe cleat. Honestly they are almost too easy to get out of now. I find when I jump and pull up with my feet, I actually come un clipped. Just as dangerous as I can loose my footing. All in all, for me using clipless is still worth the risk until I fracture something that is…
