What are your thoughts on the bikes from bikesdirect.com? I want to get my wife a decent road bike so we can ride together, but I really don't want to spend $600+ on a bike she may not enjoy riding (meaning, she may not biking at all as she is an avid runner). I've never heard of Windsor, Mercier, or Dawes bikes. Are these decent bikes? Looks like they all have the same components as entry level Fuji, GT, and Trek bikes.
