Different tools for different jobs.

You guys know me- I have a large collection of iconic steel (and some aluminum) bikes, and I ride them all hard. Very hard, considering my age.

Yesterday, rode a 30+ mile course with a close riding buddy. I was on steel, he was on his Project One Superbike. Time: 1:54.
Today, same route with the same buddy on his same bike, but I was on my sole carbon bike, a Canyon Endurace with 105. Time: 1:45.
Yep, a nine minute difference.

Yesterday was maybe more fun, but today was crazy fast. Probably could have done better than 1:54 on the Mooney, Cinelli or Pelizzoli, but still.
