I am wondering what my Apollo imperial is worth,
It has a full EX group that is in VG-minty condition, with exception of:
Dia Compe GranCompe Brakes and Levers that have a bit of road rash,
Kuwahara Tange headset
SR Seapost, Jaguar 2 Saddle
Wheels are DA laced to Araya Reds
Nitto Techtomic stem, nitto drops
Kyokuto Pro ace pedals, MKS cages and Cristophe straps.
They're sort of oddball bicycles. While the frames are well made, of decent tubing, they're oddly outfitted. They didn't use full Dura-Ace. While the Gran-Compe are great brakes are the equal of Dura-Ace, they stick out like a sore thumb. The cheap headset is even worse. On top of that, the Dura-Ace isn't even the top model. Shimano produced the old and new EX concurrently, and some of this is the old EX, notably the cranksetset. All this was an obvious attempt to hold down the original price but affects the resale value even more.
The large size could be a boon or bust. In my region, this would bring circa $200. I also believe it may be a little older than you think. Most of these models which turn up are circa 1981. 1985 would be unlikely, unless Kuwahara had leftover stock. There should be an open format serial number on the lower seat tube, which will tell you the exact year.
This bike is a part out. A mix of pretty good components, on a brand that doesn't get a lot of love, on an XL (hard to find buyer) frameset. If you have the patience/time/tools/interest in going the part out route, that will net you the most money.
+1 To comment below, both QR levers are on the wrong side.
