You have to consider your own perceptions. As cycling fans you are aware of the teams and riders connected with doping and may make your decisions based on that. To the average man in the street he doesn't necessarily put the two things together and so the brand sticks in his mind. It might be exaggerating to say all publicity is good publicity, but it is a fine line and establishing awareness of the brand is the first thing a company wants. As I said in my earlier post, Rabobank are happy with their coverage through this year's tour.
In reference to the points other people have made:
1) Local rivalry is a very different concept to what we are discussing in relation to cycling. Anything Geordie is doomed to fail in Mackem land, and vice versa. Just like no Man City supporter would have anything that could connect with Man United and so on.
2) Festina, I might not necessarily think watches in a game of word association but when I look in a shop window at watches the Festina ones do get singled out for attention as I know the brand. Would I buy one? If I needed a watch and the price and style was right then yes I would.
3) Fortunately neither I nor anyone I know needs a hearing aid. However, the only hearing aid brand I know of is Phonak, therefore I'd look at their's first. Similarly if I were talking to the doctor about which would be best for me I would probably ask about Phonak. I certainly wouldn't be thinking of Floyd Landis.
4) The case of Ratner is entirely out of context. He, as the owner of a high street store, announce that he sold 'crap', people are bound to pick up on that. There is no comparison, in my view, with what has happened in cycling.
Finally, I would not go out of my to avoid 'tainted' products. I'm intelligent enough to decide which product is best for me. Thus if Phonak are the best hearing aids, I'll buy Phonak hearing aids.
As for not buying anything that has been implicated in/ financed drug cheating then you might as well quit cycling. We all use Shimano or Campag, just like the pro's. I wear Nalini clothing of occasion, as do plenty of pro teams. I ride a Specialized bike, as do two pro tour teams (along with all those that wear the helmets, shoes etc). All that money goes into providing for the teams. It may be as kit and not as cash that goes straight into the coffers but it is money saved that can be spent on other things.
