Rivnut tool.

Anyone near nottingham got one I can borrow for a minute? Bottle boss on my ht has started slipping.

I dropped into my local bike shop. They fitted a new rivnut, and a sparkly new bolt, for nothing (and I’m not even a great customer). They do know my face though

You can do it with a bolt and nut if you don’t have any luck.

Wors, don’t know what I didn’t think of that last night. Must have been tired. I’ve sorted them out that way before! Cheers.
