Tube, 20", Select Size & Valve Type. 1 Pack or 2 Pack Money Saver. Regular or Presta Valve Bicycle Inner Tube, Sunlite, BMX, Recumbent, Stroller, Youth Bike, Toddler Bike, Trailer

these tubes are a great fit I use them on a folding training bike far exceeds the basic functions of my other tubes one thing to keep in mind though these are presta valve tubes if you have regular shrader valve rims like I do you'll need the insert converters right here on Amazon they are worth it get a couple of pairs just in case AND THEY HOLD HIGH PRESSURE FOR WEEKS hey best buy anywhere!!!!!!!

Mislabeled. Far larger than the 20” description. Reading other reviews, I now see I’m not the only one burned by this. Unfortunately, I bought these a while back as spares, and haven’t needed them till now, so I’m long past any return date. It’s too bad, because they APPEAR to be good tubes ... the presta valves are well made and have a removable core, which is a great feature. Sadly, I can’t trust the brand to ship the right size, so I have to look elsewhere for this weird size/valve combo.

I purchased this tube for my son's specialized riprock 20 bike. This was part of a emergency kit that I was putting together when we are on the trails.

Don't go by the photo. These are the standard "yellow box" tubes from Sunlite. They work fine but be aware they aren't the thorn resistant ones as shown in the photo.

When I went to install both tubes on my bike, only one tube fully inflated. The one that did not inflate seemed to have a defective valve. I contacted the seller and, surprisingly. got an immediate response. I was sent a replacement tube, which inflated well and was installed on my bike. So far they both have been fine on the bike and I'm hoping for no flats!

I'm happy with both tire & a tube - noticeable difference in ease of a ride. Tire is surprisingly grippy on almost any paved road. Really good rubber quality, highly recommend.

Great purchase. Using these for backup in case of flat on the trail. Remove tire and tube..check tire and remove any object..install new tube and inflate. Viola! Back on the road again👍

Fit fine one pin holes after a month and when I replaced it with the second it popped when I put air in it. The one that pinholed inflated unevenly like the rubber wasn't consistent. Overall really disappointed in this product.
