Springs can be a testy bunch to handle. You may need to push, pull, twist, or otherwise contort to get it on or off the bike. Our second-generation spring hook is up to any task you put it to. The tip is precision cut using heat-treated carbon steel, while the PVC-coated T-handle allows you to put as much muscle into the job as needed. We are that confident of the quality of these tools if you somehow manage to damage one under normal usage, just ship it back to us and we'll happily replace it free of charge.
