This is kind of reviving an older thread but I thought I’d add my Montare for posterity:
Serial number T5K90175 leads me to think November 1985 manufacture. Note the brake bridge and chainstay bridge are drilled through; no brazed in threaded inserts. Also notice the rack mounts on the seat stays are not the barrel type.
But when I got it, it had Deore XT M730 6 speed shifters, XT U brake, M700 brake levers, M700 front derailleur, M730 rear derailleur, FC-6206 crank, 600 “starfish” headset, and a regular Shimano threaded cup ‘n cone bottom bracket, not the later pressed in bearing type.
XT pedals, not SunTour XC.
The front wheel was a parallax type hub so it had been replaced but the rear wheel was a 6 speed freewheel and a Shimano high flange unit. I can’t tell exactly which hub as the whole thing was covered in red and black spray paint. Probably the stock unit with an RM-25 rim.
Bullmoose bars painted to match, with a Strong seatpost, silver with black head. Specialized Delta S saddle may or may not be original.
I’m thinking it’s a 1986 model that had the shifters, derailleur and freewheel upgraded with the dealer kit mentioned previously.
