I have a 2014 or 2015 Specialized Roubaix that I bought used. I recently replaced the front derailleur cable after the old one broke. It is very difficult to move the front lever-maybe why the old one broke. The previous owner had changed the left lever because it broke, but he never said how or why it broke.
I have an idea but I need to compare my cable routing to another Roubaix. I need to see if mine is supposed to have a guide on the bottom bracket that extends to the hole through tje frame or an insert in the hole. If you could take a pic of how your bottom bracket and how the cable is connected to the front detailleur I would appreciate it.
