The Danny MacAskill Lock-On Grip is the result of a collaboration between the all-things-grip people Lizard Skins and--you guessed it--MacAskill. It's the first single-sided lock-on model produced by the brand, and it's built with a variable diameter that cushions and absorbs trail chatter. The lockring is also emblazoned with MacAskill's name, which is a double bonus if you happen to be a MacAskill, too.
