Grindstone Mk2 (Prototype Defect)


WARNING! This is the prototype version of our New Grindstone Mk2. The 10 mm and 8 mm edges are at risk of breaking on this hangboard, and we do not recommend using them.

However, the 30, 25, 20, and 15 mm edges are all good to use like normal. As well as the Jug rail and the single 55 mm edge in the middle.

Normally we would not sell these, but due to an increase in demand and a decrease in stock, we will be selling these prototype defects for you to use at your own risk. We have a very limited number in stock. and when we run out, they’ll be gone forever. Please train responsibly, and thank you for Social Distancing in these tough times!
