Real Rock Feel. Rotating Power. Serious Grip Gains.
Train like you climb — with shifting holds, uneven surfaces, and no easy angles. The Crux Gear Rock Ball is designed to challenge your grip, wrist, and forearm strength with dynamic, dimpled facets that feel like real rock. Whether you're pulling, hanging, or band training, this single-handed tool adds serious tension to your setup.
Why You’ll Love It:
- Rock-Like Surface – Asymmetrical dimples simulate natural rock for varied grips and evolving difficulty
- Rotating Eye Bolt – 316 stainless-steel swivel reduces wrist strain and allows fluid grip transitions
- Versatile Mounting – Includes short webbed strap, steel D-rings, and 12kN wire-gate carabiner for fast attachment
- Single or Paired Use – Train one arm at a time or grab two for symmetric strength-building sets
- Compact + Travel Ready – Lightweight and portable with a cotton carry bag — throw it in your pack and go
Why It Matters:
The Rock Ball is more than just a round hold — it’s a functional grip trainer for climbers who want to build strength that transfers to the wall. Train wrist stability, pinch pressure, and open-hand power, all with a tool that adapts to your level and style.
It’s not just grip training. It’s climb-ready conditioning.

Compact, clever and slips into my gear bag without starting a weight negotiation.
Lightweight and durable
Lightweight, compact.
Can also use the 10 degrees backwards to have your phone almost vertical
Love the phone holder, saves me weight carrying a tripod about in my pack and gets all the best angles on the wall I can record my full route even on high climbs without spending ages setting up tripod
LOVE this piece of equipment, I love how the different surfaces challenge your grip in different ways you can also move the rope around to change the way you can grip it, been using this for my 1 arm assisted chin up work
The Quadblock is my new fave training tool. It packs light, adoreable and has sooo many uses. Perfect for warm-ups, pinch gains, finger isolation training, injury rehab and looking fabulous in my gear bag.
The Phone Stone holds my chunky phone and weighs next to nothing. Perfect for capturing the punt. I won it through one of their Insta giveaways—definitely worth a follow.
