I've just bought new wheels which take cone seat bolts as opposed to the OEM ball seat. OEM bolt specs are M12 x 1.5mm x 23.5mm but I've got my eye on a set of M12 x1.5mm 26mm cone seats for my new wheels. I don't want to buy to find they're too long, so does anyone know the max length you can run on a Mk2? Thanks!
