50 Lb vs 90 Lb Plate Specs
Total Weight
The RitFit set provides a total of 50 lb, which includes the 4-foot barbell and 30 lb of plates. This total mass is fixed for this specific configuration. In contrast, the Barbell Standard set offers 90 lb of plates alone. It does not include a barbell in the 90 lb set specification. You get nearly double the resistance mass with the Barbell Standard option. This higher weight allows for heavier loading without needing additional accessories immediately. The RitFit option is lighter, which may suit beginners or those with limited space. You must decide if you need the bar included or just the plates.
Barbell Inclusion
The RitFit product is a complete set that includes a 4-foot Olympic barbell with collars. The bar has a 25 mm shaft diameter and needle bearings for spin. This means you can start lifting immediately without buying a separate bar. The Barbell Standard product is strictly a plate set. It fits 2-inch Olympic standard bars but does not come with one. You already need a compatible bar to use these 90 lb plates. If you lack a bar, the RitFit set is more complete. If you have a bar, the Barbell Standard plates are a standalone addition.
Plate Compatibility
Both products are designed for standard 2-inch Olympic equipment. The RitFit set explicitly states that all 2-inch weight plates are suitable for its bar. This ensures broad compatibility with other gym gear you may own. The Barbell Standard plates also specify a 2-inch hole sleeve diameter. This confirms they fit standard Olympic barbells. Both options avoid the need for specialized adapters. You can mix and match these plates with most home gym bars. The compatibility is identical in terms of hole size. There is no functional difference in how they attach to a standard bar.
Barbell Length
The RitFit set includes a 4-foot barbell, which measures 48 inches in length. This shorter length is often used for hybrid or Volcano knurling bars. It is suitable for general-purpose training and CrossFit settings. The Barbell Standard product does not include a bar, so no length data applies to the plates themselves. The plates are independent of bar length. However, you must use a bar that accommodates the weight. A standard 7-foot bar is often recommended for 90 lb sets to balance the load. The RitFit bar is fixed at 4 feet. This limits the types of exercises you can perform comfortably compared to a longer bar.
Build Quality
The RitFit barbell features an oxide finish and is built with high-quality steel. It comes with a lifetime warranty against bending, indicating a focus on durability. The plates are part of this durable system. The Barbell Standard plates are described as powder coated and extremely durable. This finish typically offers better rust resistance and grip than bare steel. The data does not specify the steel type for the Barbell Standard plates. The RitFit set has a documented warranty. The Barbell Standard set highlights its construction quality but lacks specific warranty details in the provided data. Both aim for long-term use.
Who should buy each set
Beginners needing a complete starter kit
This RitFit set includes a 4-foot barbell and collars with the plates. You get a total of 50 lb ready for immediate use. The 25 mm shaft diameter and needle bearings allow for smoother spin. The oxide finish provides durability for long-term training. You do not need to purchase a bar separately, making it a practical all-in-one solution for home gyms.
Users with standard 2-inch Olympic bars
These plates feature a 2-inch hole, fitting standard Olympic barbells. You already own a bar, so buying just the 90 lb of plates is more efficient. The set includes various thickness options, such as 1.25 inches and 0.45 inches. This allows you to load your existing equipment precisely. You avoid paying for a bar you do not need.
Intermediate lifters seeking more resistance
The 90 lb total weight offers significantly more resistance than the 50 lb option. You can progress your strength training with heavier loads. The powder-coated finish ensures the plates remain durable during intense workouts. You can mix and match these plates with your current setup. This flexibility supports long-term athletic development without replacing your entire rack.

Frequently asked questions
Can I use 90 lb plates on a standard 1-inch bar?
No. The Barbell Standard set features Olympic plates with a 2-inch hole. Standard bars have a 1-inch sleeve. You cannot load these plates onto a standard barbell without an adapter. Always match the plate hole size to your bar sleeve diameter to ensure safe loading.
Is the 50 lb set suitable for serious strength training?
It depends on your goals. The RitFit set includes a 4-foot bar and 30 lb of plates. This total weight is ideal for beginners or those with limited space. It is not designed for heavy load capacity or advanced powerlifting routines. You will need heavier plates for progressive overload.
What is the difference in bar length between these sets?
The RitFit kit includes a 48-inch bar. The Barbell Standard set uses Olympic bars, which are typically 7 feet long. The shorter bar limits your range of motion and exercise variety. Longer bars allow for full squats and deadlifts with proper form.
Do I need separate collars for the 90 lb set?
The product data does not list collars for the Barbell Standard set. You must check the packaging or product description to confirm if they are included. Olympic plates require secure collars to prevent sliding during lifts. Always ensure you have safety collars before lifting heavy weights.
Which plate type is better for home gyms?
The 50 lb RitFit set is more compact. It includes a 4-foot bar, making it easier to store in small spaces. The 90 lb Olympic set requires more floor space and a longer bar. Choose the compact set if storage is a primary concern for your home gym.
Can I add more weight to the 50 lb set?
The RitFit set is a fixed configuration. It includes a 4-foot bar and specific plates totaling 50 lb. You cannot easily add standard Olympic plates to this bar. If you need to increase weight, you must purchase additional compatible plates or switch to a different bar system.
Are the 90 lb plates compatible with 2-inch sleeves?
Yes. The Barbell Standard set features plates with a 2-inch hole. This matches the standard diameter of Olympic barbells. You can load these plates directly onto any 2-inch sleeve. Ensure your barbell is rated for the total weight you plan to lift.
