Sorry toeknee, for those in Flint... there are knurls on the handle bars. the measurements are: Two and a half inches Or Four inches From center to center of the knurls The above measurements of those knurls (on the ones I have) are plus or minus, aka approximate, aka + - Are these bars year specific , or have I acquired some non banshee specific bars? #flintlivesmatter Sent from my XT1585 using Tapatalk
