POWER CHAMBER
Finally a lock with real balls! Our POWER CHAMBER proprietary locking technology uses high-strength industrial ball bearings designed to withstand extreme loads and impacts. These bearings combined with a shackle that pierces both sides of the cross bar effectively eliminate any gaps or areas of weakness found in other U-lock designs. Rated at a pull strength of over 8 tonnes, approximately the same weight as a fully loaded school bus, he POWER CHAMBER is a bike thief's mortal enemy.
