I've been in several bike shops lately that used to sell multiple brands, including Trek. Now, they all seem to only be stocking Trek (Trek, Gary Fisher, Bontrager, etc). This isn't an isolated case, I've seen it three times lately. Today, I went in a shop that used to be about 40% Specialized, 50% Trek and 10% Haro. Today it was 99% Trek.

Is Trek driving their dealer network to drop other brands, either directly (telling them to, or lose Trek) or indirectly (bumping up their sales minimums such that they can't afford to sell anything else)? Has anyone else noticed this trend lately, or is it just me?
