Hi all, I am enjoying my Specialized Sequoia on the backroads of our town. I am putting in the miles and have been toying with doing a century.

For those who have ridden a century, what kind of bike would you recommend? One with a more upright position or more aggressive position? How does a carbon compare to an aluminum for long distances? Should I consider upgrading my Sequoia to a Ruby or Roubaix?

Thanks for any advice and tips you may have to share with this newbie. I enjoy learning new tips from the veterans here on the forum.
