I'm looking to upgrade the wheels on my Felt Z5. It came stock with Mavic CXP22 and I want to upgrade to something lighter. My budget is under $500. For around $400 I can buy either the BWW Blackset Race 13 at their "Performance" level or Vuelta Team V. These will be used mainly for training and century/charity rides. Any compelling reasons why I should choose one over the other?
