OK dumbell grip. Can be loaded up to 70kg with the chrome weights from Hammer only make sure to use a tool to
fix the locks to assure they stay fixed.
The only improvement would be a better knurling and a rotating grip, to avoid it slipping I will tape them with Goat tape or
similar grip tape to improve the shape and grip of the handle.
Great that it is 48cm, its hard to find anyone making longer grips!
