This is the best water bottle cage I've ever bought. It holds the bottle tight enough so it doesn't release after you hit a pot hole but easy enough to remove while riding.

Great appearance and it's made very well, but it's odd shape limits the stuff that will fit inside and it's a bit $$. I carry a multi-tool a small can of pepper spray, and my house and car keys. Since I went tubeless I don't use a seat bag anymore and I needed something. It doesn't attach to the head tube and will spin around and end up hanging on the bottom of the top tube unless you attach it. I used two strips of Velcro between the bottom of the bag and top tube and it did the trick, A 55 for the design and construction and a 35 for the lack of attachment to keeping it from spinning on the top tube.
