The format is Chromag&';s first single clamp grip for those who like to make use of the full width of their bars, allowing you to run your hands right up to the edge. Chromag had found some single clamp grips suffer from additional twisting, which is why they designed the sleeve to snugly fit the bars towards the ends. After examining wear patterns of grips that have been through the ringer, Chromag implemented several different patterns and zones into the format to deal with the different dynamics going on in each part of your hand.
