Discover the ultimate cycling experience with the BWSHLF 27.5′ Mountain Bike Inner Tubes, designed for durability and performance. Each pack contains two inner tubes crafted from high-quality butyl rubber, ensuring that your rides are not only smooth but also puncture-resistant. With a unique formulation that includes 60% high butyl rubber, these tubes offer exceptional air tightness, eight times better than conventional natural rubber. This means you can enjoy more time on the trail and less time worrying about flats.

The sidewall thickness of our inner tubes measures between 1.1 to 1.2 millimeters, significantly thicker than the standard products available on the market, which typically range from 0.8 to 0.95 millimeters. This added thickness provides enhanced protection against punctures, allowing you to ride with confidence over rough terrains.

Before purchasing, please confirm that your bike is compatible with 27.5′ wheels and tires ranging from 2.1 to 2.4 inches in width. The 48mm Presta valve is suitable for most mountain bike inner tubes, making installation straightforward and hassle-free.

Every inner tube in this pack undergoes strict quality control inspections to ensure reliability and performance. Our tubes are round cured to provide uniform roundness, which is critical for maintaining balance and stability while riding. You can rest assured knowing that each tube has passed rigorous explosion-proof and inflation tests, giving you peace of mind during your biking adventures.

The packaging is designed for convenience, featuring an exquisite carton that allows for easy replacement and storage of your inner tubes. Please remember that all inner tubes must be placed inside the outer tire before inflation. This precaution is essential to protect the inner tube from potential explosions when inflating.
