Review on 10-Pack Black MTB Presta Bike Bicycle Road Racing Coloured Valve Cap Dust Covers - High-Quality Metal Anodized Aluminum Alloy, French Style Tire Accessories by Richard Summerall

Haven't had them in a while but bought them to sell with my bike to replace the cheap plastic bottles that came with my new road bike. Thanks to advice from other reviewers, I made sure all ten caps were properly tightened. 9 out of 10 of them fit the caps easily, and the last one wouldn't screw on until I took a closer look and realized it still had some of the processing in it. It was pretty easy to take out and so all the caps worked great. So if you're having the same problem, just make sure all caps are clear of obstructions. I expect them to last a long time and I think they look pretty chic.
