The 8-sided profile of the Octa Grip is based around simple ergonomics. The inside shape of a closed human hand gripping the bar is not perfectly round, so by using a slightly shaped grip profile Eclat were able to create a grip which simply fits to the shape of your hand, ensuring a more secure and comfortable hold on the bars. ###section### Product Specs DIAMETER: 30mm LENGTH: 170mm PACK SIZE: 2 (Pair) Colour: Gum, Black, Black With Red Swirl, Grey With Black Swirl
