Great for my mountain board!
Put them in my mountain board i fixed up. the tubes it came with (i bought it used) were cracked and through my greatest efforts to patch it, it kept leaking so i finally went ahead and bought new tubes. they got here very quickly and all i had to do was unfold it, throw it on and pump it up. the metal value is very sturdy and i felt do doubt in pumping it up really full. way easier than trying to patch it and so far its worked great and i'm glad i bought new. i don't think i'm hardcore enough to pop them yet, but for now they are a perfect fit.
