Rebel bituminous weight set 4×5 kg, 31 mm bore, Classic Disc

Rebel bituminous weight set 4×5 kg, 31 mm bore, Classic Disc includes four 5 kg plates with a 31 mm centre hole designed for use with standard 31 mm bars and barbells. Each plate uses a bitumen-filled construction to provide compact, dense mass in a Classic Disc form factor. The set is intended for strength training, home gyms and group fitness environments where space-efficient, durable plates are required to add incremental load to lifts, squats, deadlifts and barbell conditioning.

Advantages

The bitumen-filled plates deliver a smaller diameter and reduced thickness compared with traditional iron plates of the same weight, allowing more weight to be mounted on shorter sleeves and saving storage space. The Classic Disc shape offers a stable, low-profile design that is easy to handle and load. The 31 mm centre bore is compatible with standard bars and barbells, making the set versatile for a variety of training setups. Materials and construction are chosen to provide a durable surface that resists chipping and dampens noise during use.

Suitable for

• Home gym strength training and progressive overload
• Barbell conditioning and general fitness classes
• Squats, deadlifts, bench presses and accessory lifts
• Situations where compact, space-saving plates are preferred

Key specifications

• Plate weight: 5 kg each (4 plates total: 20 kg)
• Centre bore diameter: 31 mm compatible with standard bars
• Design: Classic Disc style with bitumen filling
• Construction: dense bitumen core with protective outer shell
• Intended use: barbell weight plates for strength and conditioning

How to use

Slide the 5 kg plates onto a compatible 31 mm bar sleeve ensuring they sit flush against collars or existing plates. Use spring clips, collars or safety locks rated for your bar to secure the plates during lifts. Because these plates are denser and more compact, check balance and clearance on the bar before performing dynamic movements. Combine plates incrementally to reach the desired load for exercises such as squats, deadlifts, bench presses and barbell complexes.

Usage recommendations

Inspect plates and bar sleeves periodically for wear or damage and store plates in a dry place to preserve the outer shell. Avoid dropping plates from overhead onto hard surfaces to extend service life and reduce noise. When pairing with other plate types, ensure even loading on both sides of the bar and confirm collars are secured before use.
