I also have a older Specialized Roubaix with a triple crank. The most comfortable bike I've ever owned and is my go to bike. At my age 70, the road can really beat you up if the frame is to stiff. The Roubaix is incredible when it comes to absorbing what the road will throw at you!
PS: I've had many bikes and now am down to a handfull. A tri bike which is incredibly stiff and punishing, the Roubaix
, a electric gravel bike( my newest), a folding bike for camping , and two tandems. the Roubaix is still my favorite!
