A broken steerer tube is one of those race-day failures no rider or parent wants to think about — Box One Stem Locks are built so you don't have to. Cold forged and fully CNC-machined from several high-strength aluminum alloys, they add a level of protection against losing your front wheel and fork legs if a steerer tube ever lets go. That means extra peace of mind every time you load the gate. They're backward compatible with existing Box forks and may work with forks from other manufacturers, so upgrading your current setup is simple.
