Quill stem bolt is covered I've just got a new bike (ordered online). It came all assemebled except for the handlebar stem (quill type) which is completely sideways. I believe I need to loosen the stem bolt and reorient it, however, the problem is that the stem bolt seems to be covered. There is a cap, I've removed the cap but I do not see the bolt. Any idea how I should fix this? Thanks.
The most likely scenario is the plastic cap was inserted to far. Using a drill bit slightly smaller than the access hole, slowly drill into the plastic plug. Drill just deep enough to go through the plastic when you hit the bolt head stop. Use an "O" riing pick or a dental tool to pull the plug out. If you can't raise the plug try to insert the correct size allen wrench through the hole you drilled and loosen the bolt a few turns. Tap the top of the allen wrench to loosen the wedge. Completely remove the stem. Unscrew and remove the stem bolt and push the remains of the plug out.
