CYDY Ultra-lightweight TPU Tube, 23g, for BMX and Small-wheeled Bikes, 65mm

Before use, please check for any initial defects by inflating the product to 0.35 bar/5 psi or less and immersing it in water to check for air leaks. Please note that the warranty will be void after installation. • While this product has excellent heat resistance, if you plan to use the brakes for extended periods on a bicycle with rim brakes (e.g., long downhill stretches), please use pumping brakes or be mindful of the rim temperature rise while riding. Also, if you anticipate an increase in air pressure due to heat, please lower the air pressure beforehand. • Do not apply air pressure exceeding 0.35 bar/5 psi when the tube is not mounted on a tire. This may cause it to burst. • Although the tube joints are strong, some tubes may take time (several days) to inflate. Riding is not affected even if the tube is not fully inflated. • When using a portable electric pump, please use it via a hose. The heat generated may deform and damage the valve.
