My dad just recently gave me his treasured Nishiki racing bike. He couldn't tell me much about it but I think it looks really cool and may want to restore it. I was hoping that someone could help me in determining more specific details about the bike but also give me some insights into what parts where most likely to have been mounted at sale.
The bike was purchased in Denmark hence does not reflect any of the serial number formatting presented here but I read some replies discussing how danish bikes were different in the numbering.
On the bottom bracket it says BT 2584 U just above the famous "N". Also, just above the serial number on the seat tube it says J47. Any ideas? From the numbering I would assume June, 1984 but don't know what the letters stand for. Any suggestions what a ´84 model would have had for components?
Thanks in advance

The presence of stamped dropouts, top tube cable stops and flat stay caps suggests an entry level model with a hi-tensile frame. The presence of stem mounted shift levers and brake safety levers also supports this level. This suggests either one of the Sport variants or an Olympic. The lower fork legs appear to be silver paint, as does the fork crown, part of the bottom bracket shell and possibly even portions of the headset. The questions is whether the fork blades were painted to cover rusting of actual chrome or whether they were just painted to simulate chrome. This would help differentiate an Olympic from one of the Sports variants.
The wheels have aluminum rims but they are mismatched suggesting at least one is a replacement. The pedals are definite replacements. The headset has a hanger for an era and level appropriate centre-pull brake, suggesting that the brake calipers have been replaced. I can't comment on the crankset and derailleurs due to the non-drive side photo.
It's definitely a mid-1970s entry level that has been significantly modified, complicating identification of the exact model.

The BT prefix of the serial number indicates that it was imported to Denmark by Taarnby, while the U suffix indicates 1981. However, if it was late 1981, it could be a 1982 model. The presence of SunTour Cyclone Mk II, would suggest the latter, as that was the debut model year for this version. The Shimano crankset appears to be a later replacement. We've had European mid-range Nishiki turn up under names like Trim Master, Road Master and Race Master, so it's likely some variant of the Master model name.
Thanks for the info. I guess i wasn't to far off with the year.
Mid-range? I thought the ONP was the top of the line or is it meant in accordance with the groupset? What would be the top of the line in terms of components in 1982? Suntour Superbe?

Old Bushwhacker....
Hi...brand new member here. suggested this thread.
Anyway from reading the thread intro, it seems like this bike might be quite old....
Nishiki Bushwhacker
18" frame, 21 speed, rear U-brakes, single-unit handlebar&stem
Serial CH 2543
(FYI, The site won't let me attach photos, until I make 10 more posts..)
Anyway....per your serial no. criteria, Canadian-made by Norco....1978 ?!?
Any correction and insights much appreciated.

Having said that, Cyclone Mk II was typical spec'd on mid-range models due to its price and position in the SunTour hierarchy. In 1982 the top SunTour models were Superbe Pro, followed by Superbe, then Cyclone. Depending on preference in the Danish market, it;s just as conceivable that the high end models were spec'd with Campagnolo Nuovo Record or Super Record, or Shimano Dura-Ace AX or EX. Again, you'd need to find a Danish reference, to be sure.
As for the ONP, it was a frameset offered in the late 1970s for a short period of time. They all have unique a serial number format and I have yet to see one from the 1980s.

Thanks T-Mar. An '88 is still pretty shocking....I just got it for almost nothing, seems to have all original mechanicals, and really rides nice.
I thought I read on your original post serial code criteria that Norco only made these bikes in Canada up to 1987.....?
(There is a sticker on the chain stay "Designed by NORCO")
And I mistakenly thought the term for the weird under-the-frame positioned rear brakes was "U-brakes"..what is the term for this set-up?

The brakes mounted under the chain stays are generically referred to a 'chain stay mounted brakes'. There are two styles that were typically used used in this location. One is the Roller-Cam and the other is the U-brake. Both are variations on the traditional centre-pull brake but were designed specifically for off-road use. The latter was introduced just around the time that chain stay mounting was being popular but the Roller-Cam precedes it and was not specifically designed for chain stay mounting, though it worked well in that application. There are several cases where manufacturers used both in a traditional seat stay location and even on the front fork.

Thanks again, T-Mar.
Digging into this, I perhaps have found some more 'triangulation' info to add. The derailleurs, brakes, and levers are all branded Shimano Exage 'mountain LX'. From a quick Google, the 'mountain LX' line was only available starting in 1989 (and one site says only for that one year..?).
So maybe the frame was built and painted in '88, but the bike actually finished in 1989....?

Still confused by these serial numbers
I recently purchased a Nishiki International from an estate sale. The previous owner had made many modifications such as upright bars with thumb shifters and Dia-Compe XCM brake levers. The serial number located on the bottom bracket shell is KI 09770. I am confused by the information provided by T-Mar for figuring out which manufacturer and what year this bike was made. Any help would be greatly appreciated. Thanks.

Yeah, not a Nishiki but I'm wondering if you know which Japanese bicycle factory/makers put their serial numbers on the seat tube near the bb?

There's a Nishiki Manitoba on CL, and I can't find any info on it, beyond a very low res page on mombatbicycles.com. Seller says it's a 1990, SN# 119(0? 8?)363.
It's filthy, and a bit chewed up, but no real rust, new tubes and tires, and only $25 (if it's still there). Any help would be greatly appreciated.

The serial number doesn't seem to fit but it's definitely the 1990 version based on the decals, monostay and Shimano 200GS components. This is an entry level ATB, 9th in Nishiki's 10 model, adult ATB line. Shimano 200GS was 7th in their ATB group hierarchy. The frame is plain gauge CrMo in the three main tubes. The west coast MSRP was $339 US.
The bicycle is set up as a commuter/city bicycle, with new "slick tires". The sellers mentions the possibility of needing new shift units because "shifting into the lowest gear is a bit sticky". This is not uncommon with older Rapidfire units and often can be rectified with aerosol solvent and new lubrication. It could also be a simple adjustment or cable issue, though you should budget for new units, just in case. Cosmetic condition is average for a three decades old ATB. Drivetrain wear appears to quite low. My concern is the lack of pedals and what the seller might be trying to hide by omitting them, as the price barely covers his investment in the new tubes and tyres. I'd definitely be taking my own pedals and wrench, so that I could test ride the bicycle. Also, do the usual checks for stuck seat post and handlebar stem.
You should have had this post several hours ago but we had a power outage just as I was about submit.

Thanks, T-Mar; timing is everything. 
Thanks for the info, it's very helpful. It needs a complete tear down, clean, and lube, including the sticky shifters. The lack of rust is notable because northwestern Humboldt County is damp, and everything rusts; if you let it sit still for too long, moss and lichen will grow wherever the rust isn't.

1979 Nishiki International build
Picked up a Nishiki frame for a hundred bones off of craigslist last week. He said it was a 1979 International--looks about right to me based on what I can see on the net.
Nice dropouts and fork ends, "double butted chrome molybdenum" sticker (frame feels pretty light)-- Suntour GTW dropouts and Tange chrome tipped ends. Chromed upside down "U" typical Tange style fork crown. Nishiki head badge in the the old American Eagle style (but reads nishiki). Sport touring geometry if my research serves me right. Pin striping lugs, MIJ, logos look more 80s than 70s but the frame build is more 70s than 80s-- changing of the guard I guess.
Serial number on the BB: KI 15999, with a stylized "W" underneath (not allowed to upload pics yet cause I'm new)
Came with potentially original stem, headset, and seat post. Stem is a WIII, about 3.5". Seatpost is cool and funky-- two bolt design that looks like the precusor to the modern high end standard. Headset looks like a Tange, nothing fancy, knurled top cup.
decent bit of rust in spots throughout but overall looks pretty clean. I did some steel wool and scraping work before hitting the whole thing with frame saver.
Plan is to build it up as a fast and fun ride--planning to mount my Tagaki Tourney XT crank on it (minus the granny gear to clear chainstays). That would give me 46 and 36 up front. I have a vintage sugino 127 offset BB in wonderful shape too, its either that or a new promax 108mm sealed BB. Ive got a super clean 6 speed sun tour procompe free wheel ~14-28. Planning to run my set of 700c Weinmann reverse concave rims. I ordered some fancy Challenge Dune cross tires for it too.
Probably will run diacompe center pulls (I have a pair, fingers crossed they reach 700c on this bike). I have an old TA specialties center pull mounted front rack that I think would be a fun additon---plus I don't have any decent sidepulls. I bought the Nitto Rando 44cm bars for this bike (have it on another bike and i like it). Planning to run two suntour bar cons for shifting, likely with an ARX front mech and VX or VGT rear derailleur. Ive got a nice set of drilled shimano 600 non aero levers to run as well. Ideally I can find a used selle SMP pro model or vintage Avocet touring saddle to cap it off. (maybe old SR pedals with boot clips, or thermalites)
