The 3-Way Spoke Wrench is a minimalist, light tool intended for emergency use. CNC-machined from hardened CRV tool steel that will retain its precision over time, this 4-in-1 wrench includes three spoke nipple tools and a valve extender tool.
Hopefully you'll never need it, but this handy tool will fit easily into a pocket or pack in case your wheel gets knocked out of true while you're on the road or you need to change a valve extender while repairing a flat.
