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

Garbage. They barely fit and the casting and carving are a total mismatch. What I dislike the most is that the threads are so short that you can't even lift the cap high enough to close the end of the valve. I had to retype each one and sand it down a bit to make it work. Don't worry, use plastic caps that at least have enough threads to close the Presta valves.

I have installed these valve covers on a Trek DS8.4 hybrid and a Trek Fuel EX8 mountain bike. The valve stems would break through the tops of standard plastic valve covers after a few years. Pros: - Well done. Clean knurling, tights threads, well colored - Good and tight fit on 4 hoops - Quality control of my kit was good. All 10 fit well and are snug. - No risk of the top of the lid breaking through if I overtighten it. - Enough to share with a friend. Cons: - Not yet.

They fit but not as well as my cheap original plastic. Unfortunately, I only used the first one 32 days after purchasing it. The problem doesn't seem to be enough threads as they don't thread in deep enough to cover most of the stem like I would expect from years of using valve covers. This is my first time using metal caps from this manufacturer or brand (Yuauy). I have four Presta valved bikes and wouldn't be upset if I lost them. I will be looking here for any reviews or comments that would…

More than half of the valve stem caps were not screwed on properly and would not screw into my wheels. If you decide against the advice and buy this item: Check each cap as you receive it. Don't install two and hope the rest will work in your pocket when you need them. When installing, I recommend turning counterclockwise a few times to properly tighten the threads before fully tightening. These caps are easy to break threads. The few that worked look good. Not the update I would get. When they

I'm getting used to this issue as this is my 3rd set of Presta caps (all from different manufacturers) which for some reason were made with a finer thread pitch than the spec says . for (you can actually see the difference in threads). Has an aftermarket manufacturer figured out what pitch to cut for a Presta valve? Standard plastic Presta LBS, Presta caps from various major bike manufacturers work, but every time I got an aftermarket cap it took me some pliers to put it on (never fully…

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…

Ever since I've been riding bikes with Presta style valves, I've had trouble with plastic caps breaking after so many miles/rides/hours in the sun. I'm sure it's a combination of three issues. I've always found a broken cap when checking air pressure and I personally love the caps on my bike. While many bike forums state that caps and eyebolts serve no purpose, I believe they add aesthetics to the bike and also keep the valve area clean when riding wet/muddy. fit normally. To date there are no…
