The MX55's unique rack and pinion design securely locks the weight plates into an immovable position, allowing you to push your training limits further.
Each selectorised dumbbell features a double locking safety mechanism to ensure that weight plates cannot disengage from the handset. Each weight plate is secured by a dual plate interlock feature and by locking the selector shaft in place. This means that plates cannot fall from the handset.
Always use your dumbbells in accordance with the MX55 user manual.
