This accessory is an inner tire, this is one, not a set (China Factory Shipment).

Please be sure to choose the corresponding model when ordering, accessories once sold, no refund or exchange, thank you for your understanding!

Bike and accessory may be shipped separately.

*NOTE: When replacing the inner tire on your bike, be sure to add a little air before mounting. This will prevent twisting or curling, which can lead to pinch flats. And check that the tire is even with the bead on both sides of the rim.
