Perfect fit for my bicycle. Replaced the defective tube yesterday-it was a fairly simple process. Box comes with two tubes, tire removal/installation levers and instructions on how to remove and install the new tubes. Tubes seem like good quality. Time will tell, but I would definitely purchase again.

Holds air great and feels more heavy duty than what the bike shop puts on . Caps on presta valve screw on tightly and dont strip out like my bag of replacements backups. The tire levers worked good. They feel cheaper than some ive got before but didn't break. Its nice they have a schrader valve removal tool. I will probably use it to tighten my car ac schrader valve because always pop my tubes before i ever need to service the valve. Its a 700 x 25c setup and the roads are rough around me so thats not a dig on the tube. First time changing a road bike tube myself. Only done mountain bike tubes before. Happy to get back on the road.

I absolutely adored the experience of installing this inner tube on my trusty 1993 Trek 1420 road bike - it was an effortless process from start to finish, with the tube fitting seamlessly onto the rim without any hiccups or struggles. The ease of fit was truly impressive, and I was delighted to discover that the size was spot on, perfectly matching the specifications of my bike, which has a 700x20-25c tire and a 27.5mm rim size, and the tube's 700x23-25c size and 28mm rim compatibility were close enough to work flawlessly. My overall satisfaction level is sky-high, and I must say that I'm thoroughly impressed with the quality of this tube. The only slight drawback I encountered was with the levers that were supposed to come with it - unfortunately, they felt flimsy and lacked the precision and durability that I've come to expect from good-quality levers. They seemed like they might wear out quickly or even break with regular use, which was a bit concerning. Luckily, I had my own reliable levers on hand, which saved the day and allowed me to get the tube installed without any further issues. If the levers had been better, my experience would have been absolutely flawless. However, this minor quibble didn't detract from my overall enthusiasm for the tube itself, which I would confidently rate a 10 out of 10. Without hesitation, I would wholeheartedly recommend this tube to fellow cyclists and would definitely purchase it again in the future - it's a top-notch product that delivers on its promises and exceeds expectations.

The product was very well manufactured, the tube came in a very nice and compact box showing how you guys care about reducing waste and cost, the box design was great, like the color scheme and how you guys put the installation guide on it, as for the product itself, it works great, this was my first tube installation so I did not have any levers, I only had that ones you guys provided which had me worried since it was plastic but that did not matter since it did its job perfectly, the tube was great and can handle some rough roads with not punctures. Only issue I had was with the lever itself, that yellow part inside that you use to like open the presta valve seems unnecessary and just kept falling out anyway. But, overall the product is amazing and was put very well together.

It's my second pack of this tubes. And have to say I had no issues with them. Works great, easy to install, and the price is good.

I cannot believe how bad these are. Every tube I bought blew at a seam a ride or two after an install. I would go for a ride and the tire seemed fine, I would go for another ride 5 or so days later and the tube was bad. I have been road biking for over thirty-five years and changed my share of tires, but these are hands down the worst quality tires ever. My front tire with a different brand tube has been fine for about 2 years. I thought I received bad one out of a batch run, but all the tires (I bought a few at a time on different occasions) are bad.

Solid! For well, packaged well, no complaints. Holding up!
