Well, there's a solid business reason: "why not?"

I won't buy another Performance or Nashbar product. Maybe they have improved but years ago when there wasn't much else out there I had way too many pairs of shorts disintegrate and I've seen too many pedals fall off and other parts fail. TE has some very reasonably and competitively priced shorts from quality manufacturers, and most importantly, the staff on the phone use the products and are knowledgeable -- completely the opposite of the Performance and Nashbar. TE provides the absolute best in customer service. You get what you pay for.
