Is it just me or what?? These do not thread onto my Presta valves!?!??!?!? They are the right diameter and start to screw onto the valve but only make it 1/4 turn and start to cross-thread. I've tried them on multiple bikes, same thing. Weird!!!

BEST ANSWER: Yup, it's you alright! (kidding). I bought 3 sets of these in 3 different colors and I had no issues with any of them so it definitely seems weird that they aren't working for you. All of mine thread on easily and snug up nicely. The fact that yours start to go on and then stop makes me think there may be a defect inside of them. Hopefully they aren't buggering up the thread on the valve.

Sounds like a defect. I've ordered two for my two bikes and they fit nice and snug. Though in comparison to the plastic ones that came with my bikes, they will feel like they screw in short, but they are secure.

Sounds like you got a bad pair somehow. I’ve purchased several pairs of these caps and the all have been great. They add a little finishing touch to a nice bike.

Mine thred on about 4 turns easy.
You may have received bad ones perhaps a bad tap in the manufacturing process.

They fit fine on my Presta valves with Continental and Michelin tubes.

I didn't have an issue. Bad batch? Ask for replacements.

I found the problem: it's only with Continental Presta valves, others are great! All of the plastic caps (mix-match any) fit the Conti valves because they have some give whereas the alloy caps do not deform to fit so it seems it's a Conti problem.
