27.5x1.75/2.3 35mm

I recently purchased some BWSHLF 27.5" Mountain Bike Inner Tubes. They shipped fairly quickly, was packaged nicely, and appeared just a advertised. These inner tubes were easy to install, going on in mere minutes. My mountain bike now has a new set of wheels and rides like a charm. Great product at a reasonable price. Give them a try, you will not be disappointed.

They work as intended on my ebike. I like that they came with a little nut that keeps the valve stem in place on the rim if the cap is off. Will buy more for spares. I bought these to go with new tires from the same company and am very pleased with both purchases.

Good tire

Bought these for my son's bike which shipped with the dreaded Presta valves. Drilling out the rim was not hard but not easy either. The tubes are very good. Nice value.

Perfect replacement for the inner tube's on the 29" Big Ripper

I ordered this item and it is what I wanted.I carry a tool bike under my seat on all bicycles I have. In bag are basic repair tools, tube, patch kit, and air.I have a new Aventon E-bike bicycle and ordered BWSHLF 27.5" Mountain Bike Inner Tubes (2 Pack ) believing it was the best bang for my buck.On-line images are a good representation of product.I do not know about durability as tubes are for emergency use.

I'm on my 2nd box of two and so far every time I've put a one of these tubes in my tire and ride my bike, the tire is flat the next day. To be sure I wasn't doing something wrong, I checked this time very carefully the outer tire was clean and the tire was full of air and remained full of air for 1 week because I did not ride the bike.After one week I went for a ride with my new inner tube. The next day, my tire was flat. I checked the outer tire and there was a tiny thorn from a patch of weeds that I walked my bike over before riding on the pavement.This tiny thorn could not have just barely been long enough to push past the outer tire and must have just reached the inner tube.I pulled out the thorn, circled where it was and took the inner tube out and the tiny hole was right where the thorn punctured the outer tire.The point is this inner tube is not durable in the slightest degree. It is definitely not puncture proof if this tiny thorn put a hole in it when it could have only barely reached it.So now I've put brand new inner tube #4 in from my second box of two and I'm planning to get one bike ride out of it before I have to replace the tube with a new one or fix another puncture again.

I started using these inner tubes, about two years ago. Best in the tombs in the world for the money. They don’t leak and they’re pretty hard to puncture. Get one of these tubes with a puncture sealant, money.
