Fuji had a brief fling with the Edge/Blaze pseudo-gruppo around '89-'90, with the '89 del REY (think sport-touring version of your bike) and the '89-'90 Ace. My '89 del REY Edge crankset actually took a third chainring; not sure if that applies to the version installed on the Ace. And yes, the black seat post and stem do not take well to hasty height adjustments; mine came appearing similar to yours.

As stated by madpogue, this would be a 1990 model. The serial number format is consistent with Fairly of Taiwan, a known Fuji contractor during this era and, if so, indicates October 1989 manufacture. That's late in the enough calendar that it would be a 1990 model.

Bridgestone Kabuki Submariner
 
Picked up a Bridgestone Kabuki Submariner 10 speed yesterday. Seller had it listed as a 1975, is that correct? Serial number is B685293. It has a Suntour V-GTluxe RD, Suntour FD, Suntour power shifters, Dia-Compe brakes, SR stem and Bridgestone Kabuki bars. The Osama RT-SF pedals are in rough shape. I searched for some but only found KTT RT-SF pedals. Appearance wise they seem to be the same, but I am unfamiliar with Osama pedals.

I know that it has stainless steel main tubes with aluminum lugs, and yes, it has the quill seatpost.

The serial number indicates a 1976 model manufactured very early in that calendar year. I concur, the pedals appear to be rebranded KKT (Kyokuto). While I don't have a 1976 Bridgestone catalogue, the 1975 version states a generic " light alloy rat trap with reflectors" but a 1975 Bicycling magazine road test specifies KKT RT SFAL. Regardless, it should be easy enough to determine if they were manufactured by the Kyokuto Mfg. Co., as their trademark should be stamped on the dust cap and/or wrench flats. The trademark is a simple interlocking square and circle (see attached).https://cimg1.ibsrv.net/gimg/bikefor...f18f479f0c.jpg

The pedals have FGK Japan on the dust caps, and the wrench flats have F3L/R and 57V on them with what I presume is a manufacturer's logo. A Google search of the those initials and numbers did not yield any results other than FGK as a performance exhaust manufacturer in Japan.

I thought that Osama might be a KKT model series, like Pro-Ace. However, I went back and looked in some of my old Japanese literature and found some listings for Osama brand pedals. This would appear to be corroborated by the FGK markings, which I assume is the trademark for the manufacturer, as it was pretty common for the Japanese to use a "lucky" three letter abbreviation (e.g. KKT = Kyokuto, MKS = Mikashima). That round symbol with the backwards JIS is a compliance mark for Japanese Industrial Standards.

It looks like Osama and KKT were competing brands during at least the late 1960s into the 1970s, and possibly longer. Still, it is strange that the product/model numbers are the same.

zookster 11-14-22 06:56 PM

Interesting, thanks for the history. When it comes time I will try to find some Osama pedals, or use KTT's that are similar.

I'm helping my friend move along some bikes and want to ensure I've got as much information as possible. I believe this Univega Via Carisma frameset is a 94, but I want to verify. I couldn't turn up any useful Univega catalogs.
The serial number is WEKG40085.

Recent SR find. Appears to be a ~1980 model, Semi Pro (not really), 600 Arabesque parts. Serial name conforms to Miki.

First, realize Univega never made bikes. They had others make them for them. Many assume they were all made by Miyata, which is not true. Many of the their MTBs, even in the early 1980s, were made in Taiwan. By 1994, China was in play as a possible country of origin.

In your case, there is not a lot of value there, exact year will have little to no bearing on value. If I had that frame, I would be donating. I've donated a couple of dozen of them. In my area, MTBs generally go cheap. A MTB frame, even less. Hopefully your market is better. Even road bike frames go for very little, until you get to the high end of the product line.

H2Rick 12-16-22 12:39 PM

OK.......maybe I can get these TWO identical1983-ish Schwinn World Tourists figured out.....and you're NOT seeing double.;)
#1 is s/n SA003919 with headstock badge #0150.
https://cimg9.ibsrv.net/gimg/bikefor...d0f60a45fa.jpg
Second one is s/n GD806531 with headstock badge #1048
https://cimg5.ibsrv.net/gimg/bikefor...5f156ece34.jpg
Now the first obvious difference is the "SCHWINN" and "World Tourist" decals.
The second thing is that Shimano didn't release the model "EM" thumb shifters that are on BOTH these bikes until the 1983 model year as per Shimano documentation. The earlier models were equipped with stem shifters.I have no reason to believe that these "EM" shifters were added onto these bikes later.
The third thing is that no Schwinn catalog I've been able to find shows the World Tourist 10 speeds from 1980 thru 1986 EVER being available in this 2 tone paint scheme of "Warm Silver" with "Charcoal" fenders,
The fourth thing is the pedals which are obviously different.....but both sets of pedals seem to be original as is everything else on these bikes except the seat on the 1st bike.
Fifth thing is please ignore the metal "dork disk" on the 2nd bike. I put this on because the original plastic one (same as shown on the bike in Pic #1) was in poor condition.
Now, if someone can shed some light on the big difference in the serial numbers (different manufacturers?) and badge numbers to help me solve this really perplexing mystery, I'd be eternally grateful.

JC Penny made in Japan
 
Okay this will stretch some brain cells.

1979 JC Penny bike made in Japan.
Unusual Shimano components.
The longest lugs I've ever seen (except maybe some Hetchins).
Two (2) Serial numbers!
Shimano Titlist deraillers
UG chain (uniglide chain, the fastest stretching chain ever)
Suicide levers that work very well.
Tourney center pull brakes with built in quick release half saddle.
early One-Key crank extractors built in.
Selectra cranks. Spockets twist lock in to place and are held by 1 small screw (each).
the most minimal branding. One tiny JC Penny decal below the derailleur. No name badge with just a bike logo.
Specs decals on the top tube. gearing and weight. (note the Schwinn Super Le Tour 12.2 was being sold at the time. 700 grams lighter).
Inverted bb cups used on some of the FFS cranks. No shields or seals to keep the grease in and the crud out.

9278565 and J9S7388
The first 9 in the serials seems to suggest 1979. One shimano crank has an April 1979 date code.
What factory?

Doubt if this helps much but the "Japan" decal on the ST is the same exact one I had on my Shogun. Same font, same colors.
Interesting bike for a Penney.

rickpaulos 01-08-23 01:30 PM

found the JC Penny catalog pages!
photo on the first page, write up on the second.
Looks like they only offered 1 frame size (34" minimum inseam).

rickpaulos: My 2 little contributions are:
AA) I've seen numerous 70's bikes with ALPS bars on them. One bike is my 1972 Hiawatha and, if I was at home I'd be able to show you a loose set of bars that were pulled off a Norco hulk of 70's vintage. For some reason, those ALPS "Road Champion" bars are relatively common in Canada.
BB) the Titlist rear der is definitely 70's stuff, probably late 70's which, according to what I've been able to find, was the end of the Titlist name. Yours appears to be the final version released around 1977, so that fits with the Penney catalogue dating.
IMHO, that Penney bike seems to be a parts bin special with probably a single run from a single contractor, so is probably quite "rare"......although not worth much except to a collector of oddities.......and there ARE guys like that.;)

If it's a parts bin special, whoever put it together did well - especially for a production hi-ten frame of that era.

The Schwinn Super LeTour of about that same time frame only weighed about 1.5lbs less (12.2kg / 26lb 14 oz vs 12.9kg /28 lb 6.6oz for this one). And the Super LeTour was CroMo and if I recall correctly sported Araya alloy rims.

[MENTION=20650]T-Mar[/MENTION] and all!

I purchased a bike with a repainted frame, primarily for the B.E.L.T. seat for $120 Canadian. Advertised as a Bianchi. I assumed it had been stripped of the good parts and rebuilt with a mix. Seller seemed to be honest, just not into bikes. I bought in an evening and then the cold snap hit and so I just removed the seat and left the bike in my garage. Assumed it was a Japanese made frame set.

Serial number is LS321511.

I tried your serial lists for KHS and Hodaka as they made frames for Bianchi and their number system didn't seem match this serial. Unsure what I actually had, I posted it as a thread and was told, no - not a Bianchi. Not overly worried as it was cheap and if I were just to strip it I'll not lose any money.

Can you Id it? Could it be one that follows the "S(1) (Japan): MSyxxxxx" format??

I've attached a photo of the serial number


https://cimg6.ibsrv.net/gimg/bikefor...79d3cf5127.jpg

I'll go see Jody LEE at Jester and have him decide it the "rake" issue is worth adjusting.....

Well, the serial number format is consistent with Bianchi's Japanese source and would indicate a 1984 model manufactured in December 1983. There's not much original left on the bicycle including the paint. The post looks small for the Columbus SL/SP decals and there were no Columbus models manufactured in Japan at this time. The presence of dropout eyelets point towards a lower level model. Assuming you picked this up in Canada, I'm leaning towards a Bianchi Bici I or Bici II. The post diameter may help to identify the model.

Thank you ​
I checked the seatpost and it is 25.8mm!

I believe a PO had inserted a too small post and simply torqued down the bolt. This means the post is dangling loose below the bolt and the tube has been cranked in about 1mm.

I will have to coax it back to the correct diameter. Would you hazard a guess as to the proper size? I'd have guessed 26.8.

It's difficult to say how much it is pinched. The Bici models of this era came with either a hi-tensile steel or Ishiwata Magny seat tube, depending on the model. So, there's a fairly large range of potential seat tube diameters. You'll just have to gently pry it open. then see what fits properly past the bottom of the cinch slot.


BTW, besides all the replacement components, I don't believe the fork to be OEM.

Yamaguchi sports frame - What bike is this?
 
Hi all,

I've seen many similar frames on this forum and I'm looking for some help. I'd like to re-spray this bike and possibly even add the correct decals if I can!

A few pieces of info that might help:
- Fully loaded with Shimano 600 arabesque (I love these!) [only deviation from Shimano 600 is that the rear wheel skewer is Campi ]
- Looks to be original paint since the fork and chain stay still have chrome
- the frame is very light, "YAMAGUCHI Sports Frame, Sakai Japan", "Mangalloy"
- Original bike shop sticker is from Hank and Frank Bicycle in Lafayette CA
- Serial G2027 stamped on BB
- Ukai rims

aramic 02-24-23 06:37 AM

of course a great one

If G2027 is the complete serial number, that appears to correspond to the "Fuji Special Series 84-86" format as T-Mar noted in his OP. Paraphrasing, the format is

Gy##(#), where

G - alpha month code, A-L
y - numeric year code
### - numerals, sequential numer within production run for month and year

Unfortunately, that's also outside the date range that [MENTION=20650]T-Mar[/MENTION] identified for the Fuji Special Series frames. Maybe I missed something. Or maybe he can shed additional light.
