Deluxe Replacement Bottle Cap (450/590/750/800)

The DELUXE REPLACEMENT BOTTLE CAP works great for me and it fits many different bottles. No leaks and fits tightly. Would love to see a valve in the next version to prevent liquid from spraying. Very pleased with my purchase and the quality is excellent.

As my only water bottle location available is under the down tube my water bottle is totally exposed to the dirt. This cap keeps the spout clean and ready for use. Simple and effective.

This does exactly what it's supposed to, despite riding in dust, mud, and other conditions that leave the bottle exterior filthy the actual part you drink from stays perfectly clean!

I realize Fidlock, like many companies, make you buy more than you want (can't just buy the mount piece that attaches to the bottle alone), but this just makes no sense. Why are some bottles tops able to be protected by a cover piece but not all? Make this cap for all bottle sizes, c'mon now

It's a good design that works. Only four stars bc it's expensive.
