Hello, My name is Charles S. Clark. I live in Westernport, Md.USA. I'm 68. I was so glad to have found this site thru another bike site. They had taken over Vitus and didn't have any specs on vintage bikes. I bought in the 80's or so a custom fit VITUS 979 custom fitted all Dura-Ace group from a bike shop in Frederick ,Md. I was probably in my late 20's and this bike was like a ROCKET!!!! I loved this bike, BUT I've grown as you can see older. I do have at the present a Cannondale Synapse 3 carbon, compact crank Ultegra group, with Mavic rims. I've had to upgrade the gearing in the back to accommodate the MOUNTAINS in western Maryland. My Vitus 979 is CALLING ME to bring her somehow back to life. For bonded aluminum this bike rode like a DREAM!Oh, I probably only put a couple thousand miles on the bike. When I got a job with the USPS as a letter carrier and was walking 22 to 24,000 steps a day, the last thing on my mind at the end of the day was to ride my bike. Is there any way to upgrade the components on this bike? Thank you for all your advice and help. Cheers!
