One of my children rides an old 48cm Angliru (not a 'proper' Pinarello, I know). It is a nice, useable, lightish bike with a good geometry for the road. We have various brands and non-brand bikes in the family. Take the stickers off and they differ little.
I think some people get a little too brand-aware about what are essentially just bicycles; many of which roll of the same conveyor to have different branded stickers put on them.
I hear 'born-again' cyclists on high-ticket machines chatting during rest breaks and they are often obsessing about upgrades and expensive tweaks that will have little or no benefit beyond conspicuous consumption and bragging rights at the cooler. It's fun if it flicks your switch, but it's not necessary.
The cycling press do not help. Somehow, we feel comfortable deriding the motoring press for sucking up to their advertisers and boosting 'brand image' whilst finding the same behaviour somehow noble in the cycling press.
They are bicycles and
Halfords is a bicycle shop. Good for them.
