I am getting back to riding after a long break and want to ride a century next year on the East coast. I live in PA. I have done four centuries many years ago and will be riding the same bike I did when I last rode a century 10 years ago. I am up for a challenge as during the last 10 years I have entered the Clydesdale group and will spend the winter on the trainer. I have upgraded the components from 600 to Ultegra 6500 9 speed but moved from a triple to 54 /39 on the front and went from 7 speed 12 - 19 to 12-27 on the front. Any info or guidance appreciated.
