So it's 84. Centurion ups the game on the Turbo with the top group from Suntour and those sweet looking brakes/hubs. That's a nice machine. They come with a new bike right under it as well as the Elite RS. The 3 frames are very similar except for the tubing. The Compe TA is the only one with a complete group. It probably shifts better than the Turbo and is cheaper. The lineup looks great, but then those cease & desist letters show up from BF Goodrich and KHS. They have to quit using the Turbo and Compe TA names. Dang it!
