Fitted some inexpensive stem bolts to the Boardman. The old ones had a bit of surface rust. The new ones are red aircraft aluminium. They go nicely with the frame. Very light of course.
However an hour or two later I read some conflicting advice on the wisdom of using aluminium stem bolts, including the comment to one person who’d done this that “I hope you have a good dental plan”.
The consensus seems to be – only use steel or titanium for load-bearing connections like the seat post or stem. I think I’ll take them off again and put some steel ones on from a spare stem. Perhaps I’ll use the red ones for a bottle cage.
