Three is better than one.
The Y-wrench is the home-mechanic's best friend, tightening and loosening most components on your bike while easily slipping into your apron pocket where it's always close at hand. Feedback's 3-Way Fixed Hex is made with S2 tool steel for professional-grade durability, and it has a rubber grip center and raised tool-size lettering for easy identification.
Available in a variety of bit options. Limited lifetime warranty.
