**Special return policy for inner tubes** Tubes can only be returned because if a manufacture's defect is at fault – separation a bond at a seam or valve joint. A tube can not be returned due to a puncture, improper installation or tearing at the valve joint.

Great Service

I’m always looking for quality replacement parts for the vintage Schwinn bicycles I restore at a fair price. Bikesmiths have been a great source for the tires and tubes that I need.

I’m riding with the same type of tube on the front as well as the back. The tires inflate perfectly and run smoothly.
