This is a water bottle spacer, it has a 5.1mm internal diameter to go over an M5 bolt, an 8mm external diameter and is 5mm long. Can I find anywhere that sells them at a sensible price? no I can't THIS is the only place I can find them but there's no way I'm paying that. Does anyone know where I can get them at a reasonable price? Surely there must be somewhere. I've got 2 but need a couple more.
