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.
