SQMIZE® BBP-XS25 Training Bumper Plate 25 kg – B-Grade

B-Grade: This Batch Has a Noticeable Odor

The SQMIZE® BBP-XS series is virtually odor-free. This batch does not meet that standard: The rubber has a noticeable inherent odor, which varies in intensity from plate to plate. The cause is a deviation in the material compound during production.

Everything else corresponds to the standard series specifications. Dimensional accuracy, weight tolerance, hardness, rebound characteristics, stainless steel insert and durability have all been tested and approved without any changes. The statutory warranty remains fully applicable.

The odor will fade over time. In a well-ventilated room, it decreases significantly over the first few weeks; outdoors or with the window open, the process is faster. If the plates are used in a garage, basement or outdoor area, the odor is usually barely noticeable from the beginning.

For this reason, we are offering this batch at a reduced price.

The Largest Weight in the Series

25 kg per plate, 50 kg per pair. With this weight, the bar enters the range where deadlifts and squats reach their working sets, while the smaller plates in the series take care of the finer increments. The SQMIZE® BBP-XS series redefines the price-performance ratio in the field of bumper plates: high-strength solid rubber compound, classic black design and professional quality at an affordable price.

25 kg at 76 mm

The jump from the 20 kg to the 25 kg plate costs 4 mm in thickness. 5 kg more weight at 76 mm instead of 72 mm — the compound is more densely packed in the heavier weights. On the sleeve, this is the reason why the 25 kg plates allow the highest loads before the available bar space runs out.

The entire weight is contained in the solid rubber, which also absorbs the impact; the stainless steel inner ring serves solely as the connection to the bar. It has rounded edges and runs smoothly with its 50.4 mm opening on any professional Olympic barbell with a 50 mm sleeve. The color pigments are incorporated directly into the rubber compound rather than applied to the surface.

Rebound Under Full Load

At 86 Shore A, the compound is on the harder end of the bumper plate scale. Accordingly, the rebound is low: The barbell lands, bounces briefly and stays in place. The heavier the bar, the more this behavior matters, as the bar should remain within reach after being dropped at full load. The series has undergone more than 15,000 drops in testing.

In training, the 25 kg plate provides the base load. For heavy pulling variations, front squats and cleans from the floor, the bar reaches the desired load with just a few plates per side, while the pulling height remains unchanged across all weight increments because the outer diameter remains consistently at 450 mm.

Technical Specifications

A Word About Toxic Substances

We do not use plasticizer oils rich in aromatic compounds during manufacturing, from which polycyclic aromatic hydrocarbons (PAHs) can be released. Compliance documentation in accordance with RoHS and REACH is available for the BBP-XS series.
