Sunlite Standard Presta Valve Bicycle Tubes

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.

Not much to really say about these tubes. These are pretty good, lots of reviews talking about how cheap they are made, but all the ones I've used are fine, no issues yet. They are good while still being cheap, and have decently long valves. I haven't had any issues with blowouts due to the tube, all have been the tire's fault. Also no pinch flats, but I think that's more of an operator issue. Many people rush when installing tubes, but it's important to take your time so you don't cause any punch flats after riding for a bit.

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 bought these for my Catrike. They work and they fit.

These tubes were attractively-priced, appeared to be well-made, and performed just fine ... until both failed, due to the valve stems detaching at their base from the surrounding tube material, while riding a moderately bumpy gravel road. The fact that both detached within a short time of each other raises the possibility that there was a common cause. Over-inflation, or over-tightening of the nut at the base of the valve stem, can both be ruled out: pressure was monitored carefully, and only one tube was installed with a nut (which was only finger tight). Another possibility is that a solvent (such as a lubricant) softened the adhesives used at the base of each stem; however, no such solvent was knowingly used, and the odds of an accidental exposure to both wheels are slim. I therefore suspect that the adhesive used in manufacture was sub-par and became brittle and failed ... which is why I give these tubes two stars, which recognizes that some value small was had. I would not, however, buy them again.
