ASENDIWAY 6Pcs/Set Bike Rack Hitch Mount Bicycle Car Bike Rack Strap Replacement Cradles Cargo Carrier Spare Hooks with Rubber Straps Car Racks Accessories 1-1/4"&2" Truck Hitch Red&Black

I used these to replace the cradles on my old Bell trunk bike rack, which were falling apart due to dry rot. They were very easy to install and fit perfectly. They have a small screw in the bottom that lets you tighten them to the bike rack bar a bit. The elastic straps fit very snugly and securely, which is great, but it can be difficult to wrestle them on and off. The cradles themselves are a bit more stiff than I expected, but they do have some flexibility, so they can accept larger top tubes. Not sure if that flexibility will be limited in cold weather yet, but I'll update if that's an issue. They're definitely an upgrade over the original cradles on the bike rack though, and they'll likely give me years more use out of my rack at a tiny fraction of the cost of a new rack.

Update: after 4 months, all 6 are broken. I use my bike rack around 1-2 times a week. Total crap.I've been using these new replacement bike rack cradles for about 6 weeks. Two are broken; the red plastic split in half. When they arrived, I should have received three right side versions and three left side versions. Had to install one backwards because my package contained 4 left-side and 2 right-side. Disappointed and shopping for replacements again. I regret throwing away the originals. Even broken, they were better than these.

My old Bell rack mounts were disintegrating, and these slid right onto the 1" bars after I removed the rack end caps. The red plastic is hard, so hopefully they don't damage/scratch the bike tubes. The black straps are silicone/rubber, so they seem like they'll be easy to use and secure.Better than spending $75 on a new rack!

This fits my 1 inch bike rack tube nicely. There is even a screw to tighten the cradle onto the bike rack tube. The strap has good elasticity to tie down the bike. My biggest concern is whether the plastic components will crack or break over time due to sun exposure and age.

The plastic on these is very soft, bolts strip out if tightened too much and entire cradle splits in half after a few uses, especially in warm weather.
