Hi Everyone,

Last month I knocked the curb. I unscrewed the front head to make adjustment. I found the whole front set is so tight, even if I totally unscrewed everything. Anyway, when I wanted to retight the top screw as shown in photos, I found I could just not lock the thread!

I am not expert for bike but I would like to try myself before I send the bike to the shop. You suggestion would be appreciated.

Regards,

Jing
