Product Description

The Box One Race Stem Lock keeps your setup together if you're riding hard enough to break your steerer tube.

Cold forged and fully CNC-machined from several high-strength aluminum alloys, new Box One Stem Lock offer peace of mind and a level of added protection against losing your front wheel and fork legs in the event of a broken steerer tube.

All new Box One Stem Locks are backward compatible with existing Box forks and may work with forks from other manufacturers.
