UltraverseBike Inner Tube for 27.5 X 1.75/1.95/2.10/2.125 inch Bicycle Tire with Schrader Valve – Rubber Tubes for Mountain and Trail, Cruisers, MTB, Gravel, Enduro, Downhill, City Bikes - 2 Pack

It came in good quality, easy to install well worth the price and as a plus the tools helped a lot

I purchased these tubes to run with a tannus tire armor system and larger diameter tires. The tire armor was too problematic. I am now using my stock tires with these tubes and have had no issues so far. I find it funny how hard it is getting to find quality bicycle tubes with scrader valves still. So far so good. The rides I have been taking are both on and off road, lengthly rides, no flats yet. Even after pulling a small thorn or two out of my tires. I either got really lucky or these tubes did their job pretty well. So far, my only complaints are this. The tire levers snapped while I was trying them out, the soft plastic used for the schrader core too. The tire levers would be OK on an easy to remove tire, some are not easy. Mine are not the easy kind. The are really tight against the rim, scwalbe hurricanes, and I was not able to get the bead over the rim with the included levers. Both schrader core tools shredded trying to remove the core on some of my other bike tubes. So really the only problems so far were with the included tools, not the tubes. But hey, I paid for the tubes, the tools were a bonus. Thanks for the consideration tho Ultraverse. Oh, and these were installed on an 70lbs Aventon Commuter lv2 ebike.

The tire pry tools are extremely helpful to remove the existing tire and seating the tire after installing the tube. The tube seems well built and slightly thicker then the original that came with the bike.

Inner tubes work perfectly 4/5 stars because I’m just now opening and using them but one came with a hole sadly

The manufacturer claims tubes can resist some punctures. That isn’t true. I installed an within 7 miles had a flat. Small puncture from either a pointed rock or puncture vine. I replaced the tube with the second tube in the box and 4 miles into the ride a hole at the seam. I had installed a liner so I know it was a product defect.

I had a challenge with one of the inner tubes that I purchased. I contacted Ultraverse and they sent me a full replacement in one day. They have been super easy to work with and the communication has been great. If you need inner tubes, this is the place to buy them.

I tried several inner tubes for my bike, but they kept puncturing when I was riding my bike in the city. These ones seem to hold up very well. I'm pleased!The levers that it comes with would definitely work, but I would recommend getting a good pair. I've used different levers that came with other tubes and they did not feel very solid and felt like they could cut up the tire. I recommend "Pedro's Tire Levers" they are some of the best tire levers out there.

Good enough to prevent some things, but whenever I'm riding lately after I put these tube's in the air starts to deflate within about 3 days if I dont keep the air fullEdit: was a 3 star, but they fixed the issue and it rides super good now!

Properly packed and labeled. I havent open yet as I only need this for spare while bringing when I go biking.
