The K2 Power Strap for the Pinnacle 130 is the replacement 45 mm strap that runs across the top of the boot cuff, using K2's cam Power-Buckle rather than a plain velcro closure. The power strap takes the highest load of anything on a touring boot and is the part that usually fails first.

• 45 mm cam buckle strap: the cam buckle pulls tighter than a plain velcro strap, which is where a stiff boot gets its cuff support.
• For the Pinnacle 130: K2 list this strap for the Pinnacle 130, and it should not be assumed to fit the other Pinnacle flexes.
• Restores cuff tension: a stretched or torn strap costs the boot its downhill support, and replacing it is far cheaper than replacing the boot.
• A service part: the Pinnacle line is discontinued, so this is legacy stock kept for boots still in use.
