New to the forum so forgive me if there is already a thread about this. I recently start mountain biking and picked up a 2000 (roughly) giant rincon se and I cant see to get the threaded stem tight enough so it wont move separate from the forks. Ive tightened up the top bolt and there isnt any back and forth play with the forks etc. Will tightening them collar nuts help this issue or no? If not, does anyone have any tips?
