Tech Tips:

1. Before installing your new tube, always run your fingers along the inside of the tire carcass to check for sharp debris or thorns.
2. Ensure the 45° angle is pointing away from the sprocket or brake disc side for the easiest possible air pump access.
3. When inflating, pump the tube to 5-10 PSI first to ensure it is seated evenly within the tire before reaching full operating pressure.
