Cinelli 1A stem constantly coming loose, argggh!!
This is my first post on Bike Forums.
I was hoping that somebody could give me some help with the stem on my bike, that is constantly coming loose. I bought the bike (31 year old track bike made by Rapparee, Irish family business that made high quality bikes) a week ago and since then the handle bars have physicaly come out of the steerer tube during use (starting from a stop) twice.
No matter how much I tighten the expander wedge it still works it's self loose after a few miles. I don't want to carry a 6mm allen key with me everywhere I go.
Please help as I can't trust this bike when i'm using it, which spoils the enjoyment of the lovely bike completely.
