Overview
The Rogue Cannonball Grips are a specialized grip strength training tool designed to challenge even the most seasoned athletes. By replacing a standard horizontal pull-up bar with a spherical surface, these grips shift the focus from the larger pull muscles to the hands and forearms. Whether used for pull-ups, dead hangs, or attached to a loading pin for farmer's carries, the Cannonballs are an essential implement for climbers, obstacle course racers, and strength athletes looking to eliminate weak links in their grip.
Key Features and Specifications
Diameter: 3” (76.2MM) spherical grip.
Material: Heavy-duty steel construction.
Finish: Signature Black Powder Coat with a signature "grippy" texture that holds chalk exceptionally well.
Attachment System: Includes (2) high-strength nylon webbing straps and (2) heavy-duty carabiners.
Versatility: Can be hung from pull-up bars, rig crossmembers, or attached to kettlebells and loading pins.
Sold As: Available as a pair.
Manufacturing: Proudly made in the USA.
Performance Benefits
Targeted Grip Strength: The 3” diameter forces an "open hand" grip, which significantly increases the demand on the finger extensors and forearm muscles compared to a standard bar.
Functional Training: Excellent for athletes preparing for Spartan Races, Tough Mudders, or rock climbing, as it mimics the irregular shapes and hanging holds found in those environments.
Joint-Friendly Movement: Because the grips are suspended by nylon straps, they allow for natural humeral rotation during pull-ups, which can reduce strain on the wrists, elbows, and shoulders.
Scalable Difficulty: Use them for simple static hangs to build baseline endurance, or progress to weighted pull-ups and "L-sits" for advanced core and upper body development.
Maintenance and Care
Chalk Removal: Regularly brush the spheres with a synthetic bristle brush to remove packed-in chalk and sweat. This maintains the integrity of the textured powder coat.
Strap Inspection: Periodically check the nylon webbing for any signs of fraying, thinning, or "UV rot" if used outdoors. Replace straps immediately if any structural damage is found.
Carabiner Lubrication: If the carabiner gates become sticky, apply a small drop of dry lubricant to the hinge to ensure they snap shut securely.
Storage: When not in use, store in a dry environment. While the powder coat is durable, prolonged exposure to moisture can lead to oxidation at the attachment eyelet.
Warranty Information
Rogue Fitness offers a Limited Lifetime Warranty on the steel Cannonball spheres against structural failure or defects in workmanship for the original purchaser. The nylon straps and carabiners are considered wear items and are covered by a standard 1-year warranty against manufacturing defects. The warranty does not cover aesthetic wear to the powder coat finish.
Frequently Asked Questions
Q: Can these be used with a 1" or 1.25" pull-up bar? A: Yes. The included nylon straps are designed to wrap around any standard pull-up bar or rig crossmember, regardless of its diameter.
Q: Are these too big for athletes with small hands? A: The 3” diameter is specifically designed to be challenging. While athletes with smaller hands will find them very difficult to wrap their fingers around, this "open-palm" challenge is exactly what builds superior grip strength.
Q: Can I use these for lifting weights? A: Absolutely. You can clip the carabiners to a Rogue Loading Pin or the handle of a kettlebell to perform "Cannonball Farmer's Carries" or heavy single-arm holds.
Q: Do I need to use chalk with these? A: While the texture is designed to be grippy on its own, most athletes find that a light layer of gym chalk significantly improves performance and safety during high-rep hanging movements.
