The Head Worldcup Rebels i.Speed is the GS interpretation for the general public from this American founded company. Despite the fancy marketing words such as the “Intelligence” and “Kers” technologies, it all makes sense at the first look. Racing looks, with a narrow shape, finished by a not very aggressive cut tail are the things your eyes will discover first. The magic chip stickers are well placed behind the binding so you will see them soon. Don’t try to plug your iPhone or Android device, there is no port for them, which is a pity, don’t you think?
