100g Heavy-Ball Pro Accelbooster Tennis Racquet Removable Weight Adjuster (Screw-On)

The AccelBooster Heavy-Ball Pro 100g Racquet Weight Adjuster is designed for tennis players who want to take their training to the next level. With a precision screw-on mechanism and a solid 100g weighted disc, it pairs perfectly with the AccelBooster Accelerator training system to help you build power, consistency, and real-world racquet feel — all in one compact little puck. Whether you are drilling groundstrokes, working on your serve, or just trying to develop that extra bit of arm strength and swing speed, this weight adjuster gives you a simple, effective way to dial up the resistance without fussing around with complicated setups. It fits snugly, stays secure during play, and comes off just as easily when you are done. No drama, no tools required.

Key Benefits

• Boosts training intensity: Adds 100g of targeted resistance to your racquet, helping build arm strength, swing speed, and muscle memory faster than standard unweighted practice.
• Simple screw-on design: Attaches and removes with ease using the built-in screw mechanism, so you can switch between training and match play without missing a beat.
• Purpose-built for the Accelerator system: Engineered as part of the Heavy-Ball Pro product line-up to work seamlessly with the AccelBooster Accelerator for maximum training effectiveness.
• Compact and travel-friendly: Small enough to toss in your tennis bag without a second thought, so your training never has to take a day off.
• Durable gold-finish construction: Precision-machined with a knurled edge for a solid grip and a finish that holds up to regular use on and off the court.
