The original product has been constantly improved over the last few years and is recognized worldwide as the reference in function, material, and processing. For the 2015 season, it features a new inner body that provides even more comfort for the palm rest through a three-part inner wing (patent pending) with varying wall thicknesses. The grip rubber is sourced from Germany without fillers and is made from the highest material purity. It includes a forged aluminum clamp, rather than a pressed one, as used by imitators.
