2G Circular Barbell Review
Choosing the Right 2G Circular Barbell
When selecting a 2G circular barbell, several factors contribute to comfort, longevity, and suitability for your piercing. Here’s a breakdown of what to consider:
Gauge & Diameter: Finding the Perfect Fit
The “2G” refers to the gauge (thickness) of the barbell – 6mm in this case. This is a fixed dimension if you’re looking specifically for 2G jewelry. However, the inner diameter is crucial and varies. Common sizes are 12mm (1/2 inch) and 16mm (5/8 inch).
- Smaller Diameter (12mm): Best suited for tighter piercings or those who prefer a more snug fit. May be more comfortable for initial piercings or sensitive areas.
- Larger Diameter (16mm): Offers more room for movement and is ideal for piercings that have fully healed and have space. It can also be a good choice if you prefer a more relaxed fit.
Incorrect diameter can lead to discomfort, irritation, or even rejection of the piercing. Always measure your existing jewelry or consult a professional piercer to determine the correct size.
Material: Prioritizing Biocompatibility & Durability
The material of your barbell significantly impacts its safety and longevity.
- Titanium (G23): Considered the gold standard for piercing jewelry. It’s incredibly biocompatible, meaning it’s less likely to cause allergic reactions, even in sensitive skin. It’s lightweight and corrosion-resistant. It will generally be the most expensive option.
- Surgical Steel (316L): A popular and affordable choice. It’s durable, hypoallergenic for most people, and easy to clean. However, some individuals may still experience sensitivity. Ensure it’s 316L surgical steel, as lower grades can contain nickel.
- Stainless Steel: While cheaper, standard stainless steel isn’t ideal for piercings due to potential nickel content and lower biocompatibility.
Choosing a biocompatible material minimizes the risk of irritation, infection, and allergic reactions.
Threading Style: Secure & Easy Use
Circular barbells come with different threading styles, affecting how secure the balls are held in place.
- Internally Threaded: The threads are inside the barbell ring. This creates a seamless look and is generally considered more secure as the ball screws directly into the ring. It also makes changing the ball easier.
- Externally Threaded/Loaded: The threads are on the outside of the ball. These rely on pressure to stay in place. While generally secure, they can sometimes loosen with wear and require pliers to open and close the ring for ball changes.
Internally threaded barbells are often preferred for their security and ease of use, but externally threaded options are readily available and can be reliable if properly maintained.
Other Features to Consider:
- Ball Size: 10mm is a standard size, but larger balls can be more visually striking.
- Color/Finish: Available in silver, black, rainbow, and other finishes to match your style.
- Quantity: Some packs offer multiple barbells, providing backup or allowing you to experiment with different sizes.
- Surface Polish: A highly polished surface ensures comfort and prevents snagging on clothing.

How We Tested 2G Circular Barbells
Our recommendations for the best 2G circular barbells aren’t based on subjective opinions; they’re the result of rigorous data analysis and research. We began by compiling a comprehensive dataset of available options, focusing on key attributes like material (Titanium G23, 316L Surgical Steel, and Stainless Steel), inner diameter (12mm & 16mm), threading style (internally vs. externally threaded), and user reviews across multiple platforms – including online retailers and piercing forums.
We prioritized materials known for biocompatibility, giving higher weight to Titanium G23 due to its consistently positive performance in allergy and irritation tests reported in dermatological studies. Comparative analysis of user reviews revealed patterns regarding durability and ease of use for different threading styles. Specifically, internally threaded barbells consistently received higher ratings for security and ease of ball changes. We also considered the prevalence of nickel allergies and factored that into our assessment of stainless steel options. While physical product testing wasn’t feasible across all variations, we leveraged existing industry standards for material composition and manufacturing quality to assess product reliability. Our goal was to identify 2G circular barbells offering the best balance of safety, comfort, and longevity, aligning with the considerations outlined in our Buying Guide.
FAQs
What does “2G” mean when referring to a circular barbell?
“2G” refers to the gauge, or thickness, of the barbell itself. For a 2G circular barbell, the gauge is 6mm. This measurement remains constant, but the inner diameter (size of the circle) can vary.
What material is best for a 2G circular barbell, especially for sensitive skin?
Titanium (G23) is widely considered the best material for 2G circular barbells, particularly for sensitive skin. It’s highly biocompatible, lightweight, and corrosion-resistant, minimizing the risk of allergic reactions and irritation.
What’s the difference between internally and externally threaded barbells?
Internally threaded 2G circular barbells have threads inside the ring, providing a seamless look and secure fit. Externally threaded barbells have threads on the outside of the ball and may require pliers to change the balls. Internally threaded are generally preferred for their ease of use and security.
How do I determine the correct inner diameter for my 2G circular barbell?
The correct inner diameter depends on your piercing and personal preference. A smaller diameter (12mm) is good for tighter piercings, while a larger diameter (16mm) offers more movement. It’s best to measure your existing jewelry or consult a professional piercer to ensure a comfortable and secure fit for your 2G circular barbell.
Final Thoughts
Choosing the right 2G circular barbell hinges on prioritizing biocompatible materials like titanium and understanding the nuances of diameter and threading. A well-fitting, high-quality barbell not only looks great but also promotes healthy healing and minimizes the risk of irritation or rejection.
Ultimately, investing in a barbell that suits your individual needs and piercing is crucial for long-term comfort and satisfaction. Don’t hesitate to consult with a professional piercer for personalized advice and ensure you’re selecting the best option for your body and style.
