Kizer Superbolts are low-volume hex-key-mounting screws made with the finest Chromoly steel and precisely heat-treated. In the unlikely event of a stripped head, an additional socket allows for easy removal, genius!

The set of twelve includes 4x12mm, 4x15mm, and 4x18mm sizes to meet your frame and boot needs.

Compatibility
Due to the low volume of the bolts, these are very useful in lots of frame attachment situations when you're trying to use the maximum wheel size in flat configuration for example.
