Park Tool 維修用錐形扳手/開口扳手 16mm (SCW-16)

That "Y" head design grips the cone flats without slipping off, which made truing up my old hub a much less frustrating job than it used to be. It's thin enough to get into tight spots, but the steel feels solid in the hand. Worth the upgrade over the cheap wrenches I was fighting with before.

Took my bike apart for a full hub overhaul and this 16mm wrench grabbed the cone nuts without slipping once. The "Y" head gives you plenty of leverage even in tight spots, and the steel feels solid enough to last decades.

The "Y" head design makes it so easy to get a solid grip on the cone nut without slipping, even in tight spots. It's a well-machined tool that feels sturdy in hand and has quickly become my go-to for wheel truing.
