less than 6 months but it his work bike so it got abused alot, i gave him my nitto stem off my look 'til he gets another
moral of the story: dont ride welded stems
the only reason this happened is- there was a garda/cop van beside him at the red light so he didnt blow through it, this is what happened as the light went green.
the funny thing is he sheered his left crank off the bb spindle the week before while starting off at a differents set of lights.
