I seen a post here these mounts pulled out completely . I picked up a nice used 2010 TF in XS for my daughter and it looks like very small fractures around these as well . I think the metal is a bit thin and hard in this area after forming. .......Just a heads up. .......I am sure if a bottle rack had more mating surface against the frame or was bedded down with some sort RTV sealant it would try to rock the cage from side to side. We opted for camelbacks anyway and the XS frame only has room for a very small bottle.
