You’re kidding, right? You’re going to pay me money to put your product or service on this blog?
No. You’re not.
Because if you do pay me to advertise, I will mercilessly ridicule you and your product and your sister. I will tell everyone that your product is a big, steaming, pile of donkey-doo. I will make shit up about how your [insert product here] failed during testing and killed twelve people.
However, the Internet is filled with favor-currying bike blog whores who would love to see your banner ad grace their masthead. Just google “favor-currying bike blog whores” and you’ll see what I mean.
On the other hand, if you have some really rad product or service, especially, like, if you make or sell good carbon tubulars for ‘cross with Chris King hubs, please ship me a pair and I will ride them. If I ever write a review (I won’t) I’ll be sure to say good things about them. Unless, of course, I don’t.
