Works great with my Allen Sports Deluxe bike rack. 5 starts for Ann Cook. With all the stores out of slippers (because summer), we came to Amazon hoping wed find the exact right pair. One thing I did notice was there is a little paint chip on one of the headphones arm its not big but still I purchase this brand spanking new and I expect it to be in good condition. I was unaware of this feature when I ordered them, but it came with a small directions pamphlet and I was like WHAAAT! Very nice quality, has metal pieces and has a comfortable design. Ah I?m so happy I finally got one of these! It has a few scratches just because they?re on my keychain but they still look great. We have four adult bikes on it (with the other hooks used for helmets) and the spacing is great - six bikes would be tight, especially if you use them regularly. Important to know: I have chunky feet, I walk 4 blocks to work and 4 blocks back every day, rain or shine, so it is not uncommon to get soaking wet on at least one of these rounds.
