They are great tires, not flat proof but very durable and ... pricy. I started with a 2005 roubaix comp and recently did the following upgrades(last 2 years). It's perfect now in my eyes, not cheap though.
2009 Roubaix sl pro frame upgrade
carbon ruby bars
Easton ea90slx wheelset with dura-ace cassette, and continental tires
carbon water bottle cages
and with the last tune-up, dura-ace rear derailleur and the COOLEST lizard skin bar tape.
It's addicting, but I'm done for now!
