I just picked this bike up for $130. It's in great shape, and is a high quality bike. Problem is I have no idea what it is. The headbadge says "topeka schwinn". The top tube has a "vitus" decal. Dura ace 7401 rear derailleur, Dura ace hubs, front derailleur, shifters, brake levers. Shimano 600 headset and crank. The handlebars and stem probably aren't original. Tubular wheels, Wolbler profile 20 (profile 18 front) rims on dura ace hubs. The numbers under the bb shell read "E080525. It also has a fancy stamped "CLB" and the word "Brevel" under the bb shell. There are more words, but they are underneath the cable guide. I'll take that off in a bit and figure that out. The crank has the letters LL stamped, indicating a 1987 year if the crank is original.

Does anyone have any idea what this bike is, and what year it is? also approximate value would be great.

Thanks in advance
