Grab-On are a dense foam grip, in 4 sections that slide on the bars , with some effort..
glue them on , and while the glue is wet it is a lubricant.. hair spray is another popular grip installation aide..
But you can always double wrap with common foam tape, twice... I do , the old tape goes on 1st , then new over it..
