Kenda Standard MTB Presta Valve Tube

I was having trouble with keeping air in my carbon rims. I gave up and ordered these tubes. No more losing air or flats. Easy to install, no air loss. I had to find a longer Presta valve for my deep rims. Kenda came through. Perfect tube.

I use these on my mountain bike, which originally came with shrader valves. Nice that the portable pump not matches my road bike.

Been using these tubes for several years on a MTB that I use for commuting to work on my local not very bicycle friendly roads, I'm mystified by the amount of broken glass fragments I'm constantly on the lookout for and trying to avoid which everyone knows sometimes is a hit or miss situation, that said I believe this tubes hold up rather well considering the circumstances

Find a 2.8 around town!

Itself as tube at a good price. Nice to have along on a big day if the tubeless sealant fails.

Re: my letter about the split almost new tube, I removed the front tube which was still holding air for inspection and the inner diameter of the tube in line with the valve stem was splitting in several places, ready to blow at any moment. Both of these tubes were of a batch # ending in 413.

Good standard tube with important removable valve stem for use with sealant.

I'm currently using these tubes on a recent 650b conversion. They are in a pair of used National Tire Company, (same as Nifty Swifty) 33mm wide touring tires. For overkill I have slime tire liners. Been running them around town 50 to 70psi, no problems. Am looking forward to touring/camping this summer with this setup. Gave them 5 stars for my use. Maybe lighter ones for speed oriented applications.

Pretty happy with Kenda tubes and this one is no different. Good quality and gets the job done

hey, it's a tube..it holds air and it's shape well enough. I don't get flats much except in August when the goatheads come out. I look forward to punctures. Kenda's do the job just fine. And, yeah, I'd recommend them and will probably buy more.

Great price for an important specification! I went into a bike shop to get a backup inner tube for my new bike which has 650B tires. The store representative sold me 26 1.75 inner tubes saying they were the best size for my bike tire. This was a very bad idea.

I discovered the mistake when I got a flat on a very rainy day. Through about 10 years of commuting I have found that most flats will occur in the rain. I think due to rubbish washing out into the road.

I popped out the old inner tube and installed the new one. Tried to pump it up and ... oops, it would not inflate. Found that the tube had been gouged when installing. Used a patch kit and fixed the hole after pushing my bike to a covered area. Installed the patched 26 tube and again tried to pump it up. Same issue.

Bought this inner tube size (the right one for a 650B tire) and installed with no issues. Bad store rep, bad store rep. No biscuit! Go lay down in your bed.

BTW, I really like 650B tires for bike commuting. I also have a 700c which has some advantages.

Use Kenda 650b tubes on my touring conversion bike. They are paired with lightweight 38c Panaracer Pacenti gravel tires. The last thing I want is a flat when I am touring. This tube is thick enough to to help ward off those tiny slivers of glass and wire that work their way through the tire casing without completely failing so the worst you get is a slow pin prick leak. The valve stems are short but work fine with Velocity Synergy rims. No splitting or pinch flats to date. Good value.

decent enough

Great spare tube for tubeless tire

I wish it came in a size smaller.

This tube was satisfactory for my application. I would purchase a Kenda again for my next purchase of a tube.

Tubes worked great, the wife is out riding right now

Been using it for a few months now, approx twice a week. Mostly up and down single tracks. So far so good. Would recommend this product, especially when it's on sale.
