Do it right Nick at Lloyds has the correct rivets, One pack has all different sizes,Easy to install IF the fork steerer tube is removed, Push through the hole and bend down the excess rivet from the inside of the head tube, ALSO use a little super glue as well, I have a 15 tooth cog located from a member, THANKS to all that replied, Great bunch you members!
