I have worked in the food service for 30 years. I battled a storm that produced a tornado on my way out of SC, headwinds of 70 mph in the Rockys, snow and ice, and never had a problem with the bag slipping, handling the car, or any of my stuff getting wet or damaged. I also bought a pair of Park Tool HBH-2 handle bar holder that keeps the wheel from pivoting, which helps ensure it stays parallel to the wall (no tire twist). ***And since Ive been composing my review, my 14 year old daughter just stole these slippers from me. It comes with three heights, which makes it super compatible with any type of trainer and bike. This was the perfect gift! I had to admit I rather enjoyed the analogy. Ordered size 5, true to size. The single issue I got with these hooks is when you mount them the holes are slightly not parallel to the body so the hook will not sit perpendicular to the surface. nice open sound plenty of detail.
