The seatpost bolt (8x1.25) on my 88 Bertoni broke for the second time. The first one lasted twenty years, the second one I found at a hardware store lasted one year. Just riding along and snap! the saddle is hanging, and I'm riding home standing the whole way.
If I went to a higher grade bolt, say 12.8, would that help the issue? I couldn't find one at a bike store, but I could get a 12.8 at Mcmaster Carr.
Thanks for any comments you have,
