Rogue Hi-Temp Bumper Plates
Recycled rubber bumpers rated for daily drops from overhead — the standard for home Olympic lifting and CrossFit setups. Coarser texture and higher dead bounce than virgin rubber, but built to last through tens of thousands of drop cycles.
Recycled rubber rated for daily drops from full overhead extension — the standard choice for anyone training Olympic lifts or CrossFit at home. Steel-reinforced center inserts maintain hole geometry through years of drop cycles. IWF-standard 450mm across all weights keeps deadlift setup consistent.
Pros
- ✓Rated for daily drops from overhead — no cracking over time
- ✓Steel-reinforced center insert survives years of drop cycles
- ✓IWF-standard 450mm diameter across all weights
Cons
- ✗Recycled rubber has higher dead bounce than virgin rubber — consider space
Fringe Sport Olympic Bumper Plates
Virgin rubber bumpers with lower dead bounce and a cleaner look than Hi-Temps. A good alternative for lifters who want bumper performance with a quieter drop — useful in shared spaces or on smaller platforms where bounce distance is a concern.
Virgin rubber gives noticeably lower dead bounce than Hi-Temps — plates stay where they land rather than bouncing into walls or lifting platforms. Useful in shared spaces or on smaller platforms where bounce distance is a real constraint. IWF-standard diameter and steel-reinforced insert match Rogue's specs.
Pros
- ✓Lower dead bounce than recycled rubber — stays where it lands
- ✓Virgin rubber less likely to crack or peel at stress points
- ✓IWF-standard diameter and steel insert match competition specs
Cons
- ✗Slightly higher price than Hi-Temps for lower volume of rubber
