Review on ROCKBROS Bike Bicycle Cargo Rack: Versatile, Quick-Release Rear Bike Rack with Fender for Mountain and Road Bikes - 110-165 lbs Capacity by Leo Torres

Quick release buckles make a world of difference. See, this is a four star rack that gets an extra star for adding quick-release buckles to the racks. Is it worth the extra ten dollars over identical racks? definitely. You must understand that there are three nuts and bolts that attach this type of rack to the bike frame. The road vibration alone means that you have to tighten them regularly. And they don't use locking bolts, so you'll need to take a wrench and screwdriver with you to tighten them. That's six puffs in awkward spots just to keep the bottom half of these racks from falling apart over time. With quick release buckles, just twist them every few rides and you're good to go. The fender might look crappy, but it comes in handy when driving on wet roads.
