To keep a perspective we need to understand that the decal is a marketing thing. For years Columbus used a decal only saying some sort of Columbus in some tube(s) was in the frame. Reynolds had many different decals that got mixed and matched to frames during the various high production periods. Asian bike brands (especially at the lower end) were famous for miss leading the consumer wit what the tubes really were (many 4130 claims only applied to the tube the decal was on). Many frames and their forks are made in different factories and only mated during the assembly before shipping off the boxed bike. Many small builders began to not even decal their frames with a tube brand as they understood that it's the blend, the geometry and the rider's fit that makes a good riding bike. Some tube "sets" are not offered with all the tubes of the same version, yet the decal is there in the box.

I've always taken tubing decals with a certain amount of "salt". One trusts the maker/brand (whatever a brand label means these days in the out sourcing of today's world) to have suitable tubing that results in a ride that the decal suggests should be expected. If this isn't acceptable then one needs to make their own frame and, thus, really know from what tube brand(s) it's of. Andy
