The first ergonomic grip for wide riser handlebars, a favorite in the enduro and gravity riding scene. Arms and elbows automatically come into the correct position thanks to the design of this handle. The CNC machined clamp on the inside makes the outside of the handle soft and allows the hand to be placed on the outside of the handle without pinching the nerves. The GE1 slim is the thinner version of the GE1 handle.
