I recently purchased the Inner Tube TR4 Straight Valve Stem, and I’m really impressed with its performance and quality. The valve stem is solidly constructed, and installation was a breeze. It fits perfectly into my tire, creating a tight, secure seal without any issues.

I bought this inner tube for my mini dirt bike, and it has worked perfectly. The material quality is excellent, and the reinforced TR4 valve feels strong and durable. Installation was easy, and the size (14” 2.50/2.75) was exactly as described.What I liked the most:Strong and durable materialEasy to installReinforced valve that prevents air leaksAfter multiple rides, it’s still holding up great. I will definitely buy it again when I need a replacement. Highly recommended!

Got it quick, but not heavy duty and failed on me. I would not recommend this stick with a good brand heavy duty. I usually run 3mm. This looks like one mill will not buy again.

I’ve been using the Ultraverse inner tubes with the TR4 reinforced valve for my mini dirt bike, and they’ve been excellent. The reinforced valve feels sturdy and reliable, even under high pressure, and the straight design makes installation simple. The tubes handle rough terrains well, providing a smooth and dependable ride without frequent air loss.They’re a great upgrade if you’re tired of cheap tubes that don’t last. Perfect for anyone who wants durability and peace of mind on their dirt bike adventures!

Bought this for a vintage dirtbike. Upon install the tube ripped. I was surprised for the price that the tube was not thicker which would have made ripping harder. The tire levers provided are pretty small and worthless for a motorcycle rimEDIT: the team reached out and was able to address my concerns. Bumping up my review for great customer service
