I am looking for a good road bike to ride my first century. Carbon vs alum and compact double vs triple. I currently ride a Specialized Vita Elite. I have participated in a local 34 mile Cancer benefit race and last weekend completed the 25 mile leg of the Hotter'n Hell Century in Wichita Falls TX. I am racing on and off with my brother and he recently purchased an older Specialized Roubiax Elite Triple. I just can't keep up on my Vita Elite, so I am looking to purchase something like a Ruby or Dolce type bike. Any suggestions?
