I have Exage 300 on my 1991 Miyata Triplecross http://www.flickr.com/photos/umpire5...7622871236122/. It has the Shimano Biospace triple crankset, and Exage cantilever brakes. The bike scoots like a rocket and I am not sure why...but it is the smoothest and fastest bike I have. The Shimano stuff is top notch. I have seen that even a lower level set of their components is better than most. I think you did great as long as you do a good job putting it together. Good luck and have fun!
