Standard Presta Valve Bicycle Tubes

I've never had an issue with these. They're bike tubes. I was hesitant to buy other brands because people reported that they were receiving old, dry rotted stock. Maybe that's so, or maybe people are very bad at installing tubes correctly. Maybe some people don't understand that the object that causes flats often has to be removed from the tire or it will simply flat again the first time your ride it.In any case, I just wanted to endorse Sunlite. Great price for a reliably good quality tube.Protip: get a patch kit and learn how to use it. You can extend the life of a tube for years (yes, years) by repairing them.

Has held up really well over the years! These tire tubes have performed very well when needed to repair a flat. Easy to use and they have been perfect. No issues!

I purchased these tubes to use on my Bike Friday pocket rocket.I can imagine 451 bmx racers and possibly recumbent riders also using them.They are nothing special, other than that I have had only the usual amount of flats.After a week of ~40 miles of riding, they tend to go from 80 to 50 psi, so bear this in mind.However for the price the tube is decent. One of my major problems (which I have had with sunlite before) is that sometimes the presta valve assemblies seem far too brittle for normal use- I shouldn't have to worry about snapping the top of the valve off while hurriedly changing a tire in the rain.To this regard, they are very solid.So verdict- solid, no-nonsense tubes. Probably not the lightest, probably leak more than others, but for the price, not bad.I would take these on a tour.

Smooth stem plus removable core is too hard to find. Wish all tubes were like this one

Tubes work as described and seem to be good quality.

Tube is a tube seems fine 26x4. It's a tube... Please note if you intend to add some sort of tire sealant they have non removable presta valve cores. So it's some sort of hack to install tire sealant or run um raw and hope for the best. Where I'm at, due to thorns in the area it's a must. And yes I am familiar with tubeless setups but they are not for me. Anyway DO NOT buy if you intend to use sealant. Not sure if the tubes vary from batch to batch so YMMV.

I live in the North West. If anyone has ever biked out here you know about goathead thorns. These mother f====rs use to make my life hell. Since switching to a 10 speed/road tires that is no longer an issue. 100 PSI sure can repel ALOTTA HOLECRAP. I useto have standard 50-80 PSI tires on my bikes.. they got flats WEEKLY... even the green goo would make it so the tube would last for a month...Since 10 speed, 100 PSI+ tires? I have gotten ONE flat in 6 months, and it was a PINCH flat because I couldn't air the presto valve up ANYWHERE. (Only pet peeve is presto valve, however, the valve itself is great, just the rarity of compatibility is annoying.I have these tubes last me 6+ months of weekly riding of 50+ miles. Hell, my front tube is over 15 months old, ahhahha.

Good product. However, it is very easy to make a mistake when choosing the right size. You need to pay attention to the ISO and product number! Because there are 2 different sizes on the packages with some dimensions. This is misleading because the Sunlite 16 x 1.375 (349 x 25) / 32 mm (product #63138) is approximately 2 inches larger in diameter compared to the Sunlite 16 x 1.35 ISO 305 (product #63191).
