This is a rear carrier for a Giant "ROCK" mountain bike. I don't know the model number, but I found a picture of the "ROCK," so please check photos 11-12 of the listing. I stored it without using it much, but there are some scratches and rust on the screws. I also have the cargo straps, so I'll include them (I don't think they've deteriorated. Sorry if they have(^^;). Please consider this item, understanding that it is a used product. Thank you for looking.
