FAST & SECURE WEIGHT ADJUSTMENT: Change training intensity in seconds using the VEKTOR quick-adjust locking system. Simply loosen the precision knurled screw slightly to add or remove plates, no full disassembly required. The secure locking mechanism keeps plates firmly in place, allowing smooth transitions between sets without downtime.

STABLE, RATTLE-FREE CONSTRUCTION: Each weight plate connects using an interlocking alignment system supported by dual safety pins. This design eliminates movement between plates, reducing noise while ensuring a tight, secure feel during every repetition.

TRADITIONAL DUMBBELL FEEL: Unlike many adjustable systems, the VEKTOR Series maintains the balance and handling of a fixed commercial dumbbell. The solid steel handle features medium diamond knurling, providing confident grip control for presses, rows, curls, and heavy strength work.

ALL-METAL BUILD: Constructed entirely from powder-coated steel and alloy weight plates, the VEKTOR dumbbells are built for years of consistent training. The angular head design prevents rolling and allows safe placement on floors, racks, or benches between sets.

VERSATILE TRAINING: The flat-sided construction improves stability for exercises such as renegade rows and floor-based movements, while the smooth outer edges allow comfortable thigh placement before pressing exercises like incline presses or shoulder presses.

VEKTOR ECO-SYSTEM: Your adjustable dumbbells are just the beginning. VEKTOR weight plates are fully compatible with optional attachments, allowing you to expand your training without purchasing additional weights:

• Adjustable Kettlebell Handle – Convert plates into a kettlebell (up to 40kg)

• EZ Curl Bar (11kg) – Targeted arm and accessory training

• 1.4m Barbell (12.6kg) – Full-body compound lifting

• Dumbbell Stand – Ergonomic loading and organised storage
