I recently bought two old Takara road bikes. One of them is an early '80s Tribute with a touring style geometry. The other is a mid/late '80s (I don't know the model) with race geometry and 700c wheels rather than 27". I only plan to keep the latter of the two, but my question is which component group should I take? The older of the two has Suntour Alpha 5000 shifters and rear derailleur and Suntour LePree front derailleur as well as a Sakae crankset and Dia-Comp brakes. The newer has Shimano Exage Sport front, rear derailleurs as well as shifters, crankset (with biopace...boo), and brakes. Both sets of components perform fairly well for their age. My plan as of now is to replace the bottom bracket and put on the Sakae crankset and also use the Shimano Exage drivetrain minus the crank and the Exage brakes. I don't really know much about either Suntour nor Shimano Exage. Where did they stand in something like the Shimano line now days? Does anyone know anything about either of these lines? What would you recommend?
