“The Cervélo S5. The winningest bike in the 2016 Tour de France. 5 stages. All terrain.”
How many S5 bikes do you think I’d sell?
Anyway, I sold another S5 today. And no, I didn’t use that Winningest line.
If you want slogans that sell, ask the people who have to sell your product. Or at least ask someone who is willing to put himself into the hearts and minds of potential buyers.
