Grindstone

The Grindstone is the next evolution of Tension's flagship hangboard. Combining unmatched comfort, improved design, and the utility of our former hangboard models, the Grindstone represents everything we’ve learned about designing and manufacturing single piece hangboards.

The Grindstone is based around an asymmetrical edge layout to ensure equal grip spacing for each edge size to deliver a more consistent training stimulus.

The custom edge profile eliminates typical pressure points of a standard rounded edge,  making it possible to train 4, 3, 2, or even 1 finger at a time without the need for designated pockets.
