I have a very nice 1983 Centurion Turbo for sale! The frame is made out of Champion #1 (Tange 1) tubing w/ Suntour Pro chrome dropouts. The Turbo model was only made in 1983/84. I think it followed their Professional Models. This was the top of the line Centurion model back in the day! I bought this with most of the original equipment, but I changed the original mechanical components (Suntour Cyclone Mark II) with Shimano 600EX and a rear Dura Ace 7700. I wanted to keep as original as possible, but could not find a rear Cyclone derailleur and downtube shifters. I still have the original Cyclone front derailleur if you want it. The Shimano 600/DA equipment is better than the Cyclone Mark II anyhow. I know the 84' model came with full Suntour Suberbe Pro, and that is considered the best, but the 83' version came stock with Cyclone, so I don't feel bad for changing it to 600EX. It has the original Araya 20A ultra narrow rims w/ Suzue Sky Road sealed hubs, Aero Mighty Comp crankset/ pedals, and very hard to find original Dia-Compe Aero Grand Compe AC-300G brakes. New tubes, cables, housing, hoods, and Continental Ultra Sport tires (700x25), but has room for 28's or maybe bigger. I also put on a hard to find vintage Avocet Aero aluminum seat post w/ Turbo saddle. It's just such a sweet ride and it feels like a racing machine when you are on it. You can definitely feel the difference while riding on this bike, compared to other
