Based on the serial number, the frame was definitely built in 1979. The serial number isn't very high, so I doubt it's a 1980 model manufactured in late 1979. The decal scheme is correct for the era. Enjoy your new acquisition.

Oh nice! Thank you T-Mar. Yeah isn't that seat post interesting? I've never seen one like it but to be honest most of the 1970s models I've worked on were lower end than this one.

Thank you for posting about Vintage Nishiki bikes and the serial number database. It helped me feel good about making my recent bicycle purchase. I am fifty and out of shape, I haven't had a bike I liked since I was 15 when I had a small Nishiki Mixte. I have injuries that make biking a better form of exercise so I looked for a vintage Nishiki. On craigslist I found a beautiful one: a blue 19" 1978 Nishiki Olympic Royal Mixte cruiser in fantastic condition with nearly all original parts (appears only seat and tires were upgraded in the 1980s per the bike shop guy). Many thanks for your posts, they helped me decide it was a great bike for me. I've ridden more in the last week than I have in 25 years. (Note I tried to post photos of bike, components and serial number like you asked for, but as I am new to the forum it is blocked.) Serial number: KH 04329 with a stylized W below. Incomplete components list: Tube labeled chrome molybdenum, Suntour Vx front and rear derailer, Crank says Super Maxy, Suntour "Power" Shifters, Dia-Compe brakes and brake handles, "Silver Win" handle bars, ARAYA rims "27 x 1 1/4 w/o (N)" (Aluminum).

Welcome to the forums. The site has a 10 post minimum before pictures can be attached to a thread, to discourage spam. However, the pictures are deposited in a gallery album. Here's link to your photos. https://www.bikeforums.net/g/album/20036379
The frame was definitely manufactured by Kawamura in 1978 and the frame number is low enough to be a 1978 model, as opposed to a 1979 model manufactured in late 1978. Based on the thorough description and pictures, it does appear to completely OEM, with the exception of the saddle and tyres. It was 4th in a 9 model adult line. Two additional facts are worth noting about the 1978 Olympic Royale, First, 1978 was the debut year for this model and second, the mixte model came in both dropped and all-rounder handlebar styles. However, if you wanted the latter, it was only available in blue, which was officially called "sapphire".
Good luck with your recuperation and exercise. Enjoy your new acquisition.

Hi T-Mar, everyone, just got a used ultra pro , SN says WN620692 - can't seem to figure out when was this made. Can you please help out? If it helps, this one is a 27 gears bike - not certain if any of the initial equipment was replaced (later after initial purchase). Most of these bikes as far i could see have 20 gears instead, so i am a bit confused about this.
also, it's got a carbon fork - perhaps this helps as well.
many thanks,
Ciprian

your Ultra Pro may be a European model. The serial number looks like a Danish VIN, except it does not have a letter at the end. If it is a Danish VIN then the letter at the end indicates the year. Also the WN indicates imported by Nordisk Cykelfabrik A/S.

Hi T-Mar, if I may, could I ask about my lovely Araya? This is the most "together" bike I have ever had, bought as a basket case, literally pulled out of solidified earth here in Arizona. I understand that Araya made only a short foray into making complete bikes. The BB shows C432754, nothing on the dropouts. Anything you might mention or direct me to would be gratefully received. Picture above.
Araya models manufactured by Araya typically have a serial number format starting with ARY. Consequently, this would appear to be contract manufactured. Those particular versions of the SunTour VGT and Compe-V derailleurs suggest a relatively narrow range, circa 1974-1977. Based on that plus the serial number, my leading candidate would be a 1974 model, contract manufactured by Bridgestone. Sorry, I don't know the bicycle model name.
the serial number on your Araya is an Araya serial number, not Bridgestone. In 1977 Araya started to put an "ARY" prefix on their serial numbers. Araya frames built prior to that had serial numbers without the the prefix.
The letter "C" at the start of the serial number is for the month of frame manufacture, C = March. The first digit "4" is for the year of frame manufacture, 4 = 1974.
The bike looks in very good condition for 1974.

Hummer, thank you so much for the information on the Araya. It's great to know its age with more certainty. The bike is a joy to ride, a great match between my dimensions and capabilities, and those of the machine. I see that you are in Rupert's Land, I dimly remembered it from my History lessons and take my hat off to you there in chilly Canada. Here in the greater Phoenix area even a frost is a thing to marvel on and post on Face Book, and we worry about the low temperature affecting the compound of the tyres. Best, Toby

Nailed it on this one-- its a JPR.
Waiting on a BB derailleur cable guide and some bar end parts before the bike is finished. Mounted the Challenge Dunes and they look great.

Nishiki Ultimate
Didn't need another machine and it was 30 dollars above my price these days.....(I just couldn't pass on it).....The campy parts have been removed and replaced with full Shimano 600.


A bit rusty, but it'll clean up nicely.

Has campy dropouts.

Serial Number: W90038091
Cant find this serial number anywhere in the data base. Also has 12585129 written on the bottom bracket shell. The original decals said it was a nishiki with Tange 1 tubing however I just want to know if it is in fact a nishiki and what year and model it is!
some photos of the frame:

I'm very impressed by the longevity and comprehensive coverage of this thread, came upon it whilst searching to identify a frame number on something that claimed to be a Bob Jackson, but is not. It's been butchered about a bit, I can't add photos I'm afraid, but the serial number is KS01110. Components were a mix of all sorts of good bad and ugly so won't help with the year I don't think. It's probably going for scrap but I'd like to know what I'm throwing out!
I know this reply is a little late.

This serial number is probably for a frame manufactured by Tsunoda. The serial number stamping font and format are the same as Tsunoda. The first letter "K" is for the year of frame manufacture. I am not sure but I believe that K=1980. The letter "S" is for the month and I am not sure which month.
Tsunoda frames are found with the Tsunoda brand name and other brand names.

The serial number is probably under the down tube or lower backside of the seat tube. It may be difficult to see because the paint is thick.
The paint style is not uncommon for 1990.

welcome to the forum. I have seen that format of serial number before and it was found on Nishiki models from New Zealand. The two models of Nishiki that I have seen from New Zealand are Prestige and Tri-A, and both were reported to be year 1985.

Hard to say dude-- I don't have a 1986 International, and I cant find a catalog online. Not even sure that a catalog could tell you.
But you're using a SR Laprade 26.8mm and it works? Could be a 26.8mm seat tube then, no?

Barbarian
Hi everyone - this thread is not just a nugget, but an ore of golden info.
I've got this Nishiki Barbarian (in Sweden). Serial # is EH403713 (unless more is characters are hidden behind the cable guide). I haven't found any info, pictures or catalogs that have helped me date it.
Can I assume it is a 1988 by the "H" in the serial? Does anybody have a link to 1984, -5 and 8 catalogs?
Other info:
I'm new on the forum (long time lurker), so I can't share the photos directly, but here is a link imgur [dot] com/a/2sPcjZK
Frame stickers say "Handmade by Nishiki", "Barbarian", "Tange MTB Cr-Mo Tubing, PG tubes".
Suntour deraillers and shifters
SR Custom triple crankset that very much feel like its oval.
Sansin hubs and araya rims.
hatta vesta crown

Nishiki international performance equipe- need info!
Picked up this super red and Shiki international 4130 CR MO And found this thread hoping to find some more info. Pick it up from the gentleman at a garage sale he didn’t have any info. Anything that you guys could give would be super appreciated! I tried uploading photos, but it saying I can’t because I haven’t posted enough on bike forums. The bike is white with a splattering of black and it’s a change number one made in Taiwan. Has the red and blue does Shiki emblems and it says it’s the performance equip
