How durable is the bars finish? 

The BLK BOX Hybrid Bar – 15kg features a bespoke coloured finish, offering a good level of corrosion resistance and durability while greatly enhancing the athlete to feel the knurl. We recommend regular cleaning of the bar using a nylon bristle barbell brush. DO NOT clean the BLK BOX Hybrid Bar with cleaning or disinfectant/sanitising spray or any other chemical cleaning product, as this can damage the bars finish. 

Why are bearings important? 

Bearings are introduced into barbells to ensure a smooth and/or fast spin when performing Olympic weightlifting movements. This spin reduces the force exerted on an athlete’s wrists during these movements. The BLK BOX Hybrid Bar has 4 sets of needle bearings, ensuring a smooth spin under heavy loads and reducing the torque experienced by athletes during the movements.  

Why is whip important? 

Barbell whip is phenomenon best recognised where the bar seems to bend during a movement, then snap back into its straight position. It allows the athlete to introduce momentum into their lifts that is caused but the bar, and not by them. A lifter can use the whip of the bar to help propel the weight upward adding incremental gains to their training. Although it removes some stability from the bar, a bar with high whip can handle a lot more weight before bending permanently than a bar with lower whip.
