Hello all, without sounding like a total newbie, i'm after some basic red valve caps for my mountain bike, i've been looking on ebay but many on there seem to be listed for cars and bikes (which i assume is motor bike). Would these fit my mountain bike, or are valve caps designed differently for cars and bicycles?

Here's what i was thinking of buying, it doesn't state whether they'll fit mountain bikes:

Thanks for any help
