Many of our club members ask about triathlon wheels for their bikes. I ride a traditional road set-up with Mavic Ksyriums which I love but I do more riding than anything else. I would like to solicit some input from RSTers about their experience with disc wheels or other time trial / triathlon specific wheels. Which have people used? What do you like / don't like? Are they worth the expense, etc? I would love your input.
