Unisex's BMX Inner Tube, Orange, 20 x 1-1/8-1-3/8

I've had zero issues with standard rubber tubes, and usually only replace them when the valve stem stem gives out - I ride park/dirt only and rarely get pinch flats or blow-outs. So after seeing these everywhere, I decided I wanted to try these "amazing" tubes everyone is talking about.They are unlike any tube I've ever seen, so I followed their directions for install and inflation - got it to about 65psi no problem, tire seated properly; we're looking good.I only got 2 runs in at my local dirt jumps until I heard the dreaded hiss coming from my front tire. Upon checking the tube, it split/tore along the bottom side that sits against my nice, clean, Odyssey rim strip. I checked both before installation, and after the flat, for any debris or sharp edges in the rim - there were none. Total garbage.These are lighter, but I couldn't feel a difference at all (I run Ti-spokes, THAT makes a difference) and certainly not worth the price; now I'm just waiting for my rear tube to blow any day now.I'll stick to the super thin rubber BMX tubes I've been using for 20 years that are $4.00 each and support my local shop.

For this price, I would expect them to pump up evenly. while trying to air up my tire, I kept getting weird flat spots with no air. I finally took the tube back out and pumped it up and saw this. Unfortunately I waited too long to install them, so I'm sure the return period is over.

This listing is for 20 x1 1/8" - 1 3/8" tubes. This size only works with the very thin-width rims/tires that come on mini and junior BMX race bikes, built for young kids (5 to 11ish years old). The rims are the same width as road and gravel bikes--nothing close to what standard BMX bikes have.The first reviewer said he rides dirt/park exclusively. No dirt/park bike would ever have 20 x1 1/8 - 1 3/8" rims; they're all 20 1.75". All of them. He bought the wrong size--by a long shot.The second reviewer obviously bought the wrong size as well, evidenced by his uploaded photo. The "flat spots" he was talking about, are actually the areas in which the tube held its intended 1 1/8- 1 3/8" inflated diameter. The other areas are where he managed to balloon the tube far beyond its intended width by inflating it inside the wrong size tire. I'm sure this is how reviewer 1's tube looked inside of his tire too, and why it obviously didn't hold up.These tubes are actually everything they are touted to be. They are 60% lighter and significantly more puncture resistant than butyl rubber tubes. You just have to buy the correct size.

Produits a éviter absolument. Mon fils les as montées hier sur son BMX. Elles ont éclatées après 1 journée d'utilisation.
