Bicycle Inner Tube Protection Pad
Material: Polyurethane polymer composite
Weight: about 33-53g (see product parameter list for details)
Uses: It can greatly reduce the chance of the inner tube being punctured, thus protecting the inner tube.
Tip: 26 inch anti-stab tire pad can be used for 14/16/20 inch because the long part can be cut off; and 451 can use 700C as the same reason.
