ION fitness Fractional Plate Set 15 Kg

Overcome your plateaus with this Set of Fractional Olympic Plates ION fitness Weight: 15 Kg set of micro-increments (0.5-2.5 kg), made of SBR rubber with a steel core.

With ultra-precise weight tolerance (±1%) and IWF color coding, they allow controlled and safe progression.

Compact diameters (134-210 mm) and 51 mm Olympic hole. Essential for powerlifters, weightlifters, and rehabilitation seeking improvement through progressive overload.

Featured Highlights ION fitness Fractional Olympic Plates

• Range from 0.5 kg to 2.5 kg: Five fractional weights that allow minimum increases of just 1 kg total on the bar (0.5 kg per side) up to 5 kg total (2.5 kg per side), the micro-controlled progression that maintains progressive overload without intimidating jumps.
• Allows sustainable linear progression: With increments of 1-2 kg total, you can progress session after session for months instead of stalling trying 5 kg jumps.
• SBR rubber + natural rubber: Hybrid composition combining SBR (high-strength synthetic styrene-butadiene rubber) with natural rubber to provide exceptional durability, vibration absorption, and superior grip texture.
• #45 Steel Core: Medium carbon steel insert #45 (equivalent to AISI 1045) providing exceptional strength, precise weight, and long-term durability without deformation.
• ±1% weight tolerance: Each plate weighs within 1% of the marked weight, meaning a 2 kg plate will weigh between 1.98-2.02 kg, exceptional precision surpassing the ±2% of standard bumpers.
• Critical for micro-loading: When working with such small increments, precision is key – a 0.5 kg plate with ±3% tolerance could weigh up to 0.515 kg, completely unacceptable.
