Amazing Tools To Repair Old Bikes and Build New Ones!
For more than 30 years, the J. A. Stein Company has been designing and manufacturing tools to simplify the jobs that make life difficult for bicycle mechanics — especially when working on bikes that have seen hard use. We love the challenge of creating solutions to the issues that inevitably arise in the workplace, and have compiled an extensive “how to” list for jobs that are not easily solved. This is where our tools really shine — by bringing the joy of success to our users and elevating them to hero status in the eyes of their customers. If you have a suggestion for a new tool that you think would help with a specific issue, let us know!
