Aldo nuthing. I am saying mm becos we have fownd that iff your rear spindel is out by even a cuple of Mill , the difrence can be a lot out at the tier edge , wen alineing the two wheels ,I have fownd that 2'mm out at the spindle end can put the edge of the tier out by eneything between 5,to 10, mm , wen alineing the wheels depending on the bike and the swing arm , frame ,Jigging alinement wen it was welded up at the fabracaters , What allso makes a diffrence is ,you need to do up the back spindel tight as well , well take the tenshon up in the swing arm , wen alineing the wheels , as iff you dont it can make up to 5,mm diffrence on the spindel as all the swing arms that I have come akross on aprilias are all under tencion wen Tourq'd up , iff that makes sens .:thumbup
