Dekes Posted July 6, 2008 Report Share Posted July 6, 2008 I was taking apart my bike and saw this weird bolt at the non-drive side of my BB. It would be nice to unscrew it so i could maybe clean the inside of the bb. I have no clue though whether it's right-hand or left-hand thread or even whether there is thread or not. Has anyone seen this before or does anyone know if this bolt can be unscrewed or what it's function is? Thanks. Quote Link to comment Share on other sites More sharing options...
trials_pimp Posted July 6, 2008 Report Share Posted July 6, 2008 Thats the Lock ring for the BB Bearing preload Nut. Undo that, then Undo the Preload nut and you can remove the Axle and Bearings. You could remove it to clean inside, for what its worth, but remember the old Addage, if it aint broke dont fix it. Quote Link to comment Share on other sites More sharing options...
