I have several SB's, so I tried to confirm their dates of manufacture using their serial numbers. Not sure the guide works for them, though. Like the gentleman up-thread with the SB Whistler, mine have SN's that start with two capital letters, followed by 5 numbers. That doesn't seem to fit the Yamaguchi system suggested for them, as it starts out with letter-number-letter. The ones that do appear to correspond (during the mid-80's) to the SB sequence look to be those of Fuji, Kawamura, Maruishi, Miyata and Tsunoda - but of them, only Maruishi's produced dates that make sense.
Specifically, mine have SN's that start with either F (like both the Whistler's and the SB Mystery Bike's) or G; followed by either H, N or S. Assuming the second letter refers to a fortnight, Mariushi's system would give them dates ranging from April '86 to April '87 - certainly a period compatible with their colour schemes. Do you think Maruishi could have been the (or a) builder of early SB frames? Or have I muffed something? Thanks so much, BTW, for putting together and sharing all this info!
While we've definitely seen Yamaguchi manufactured Steve Bauer, that doesn't mean they were the only contractor. The guide is a dynamic process and I am adding new sources on a fairly regular basis,. as they surface and are identified. Yes, I saw the bicycles you mentioned and Maruishi is definitely one possibility. Unfortunately, Steve Bauer don't surface very often and I have few samples in the database. It you want to submit your serial numbers and pictures, that may increase my confidence in Maruishi being a contractor for the brand.

T-Mar - Tried responding with pix, but they wound up in the gallery, without my message appearing at all (??). I presume you can find them though, and I hope they help! (I do find it curious that two of them have the NS on the BB, but the third is on the seat tube. It'd make you think a different company made it - yet the SN's all follow the same letter-number pattern...)

It's normal for pictures to default to a gallery album under the member's forum ID, when the member has less then 10 posts. I regularly refer there for picttures from new members. However, in this case I can't find your pictures. They should be less than a day old and near the front but I don't see an album with your forum ID. Regardless, since your next post will be your 10th, you should be able to attach pictures to your post.

Hmm...I can get to them by going to the gallery and clicking on "My Pictures" - but I don't actually see how one goes about finding someone else's.
I'll re-post.

All the pics, even those for members with less than 10 posts, should be here https://www.bikeforums.net/g/albums
However, there might be restriction on new members viewing other members albums. I'm not sure. Regardless, it's a moot point now that you've achieved 10 posts.

Based on the liveries, they are all 1986-1987 models. This raises my confidence in Maruishi being the manufacturer but what escalates to the matter to "almost certainty" cataegory is the tubing decal of the Mistral. The layout is suspiciously reminiscent of the generic tubing decals applied to Maruishi models of the mid-1980s. Similar decals are also seen on Maruishi manufactured Nashbar bicycles of this era.

It was fairly common for marketing brands such as Steve Bauer to use multiple contractors. They were always looking for the best balance between price, workmanship and materials, so contractors could change from year to year and often their were different sources for different levels of bicycles. Based on your collection, it would appear that Maruishi was the prime source for at least the entry level and lower mid-range models during 1986-1987.

Based on the serial numbers, the Mistral and Chinook should be 1986 models, while the Cyclone should be a 1987 model manufactured in late 1986. I've seen cases where manufacturers have changed the serial number location each time they rolled over the serial number sequence and some who used alternate locations depending on the customer, but neither case would seem to fit your bicycles.

Thxs for posting. However, if you want to survive on the forum without being constantly called out, you'll have to learn to post photos taken from the drive side, so that the drive train components are are more visible.

Thx for the info, T-Mar - and the tip. Just posted some shots of my ''new'' SB on the ''Mystery Steve Bauer'' thread. Hope I got it right!

MMMmm..I got an 80's Sears road bike, I guessed it was an FS10, but none of your numbers are near those on my bike, for instance, mine doesn't have any letter codes, but an 8 serial number whose first 3 numbers are "702" followed by a "489" underneath followed by a dot and another 6 numbers... any ideas who would have made this, and dates?

I can contribute with two serial-numbers, I recently bought a Miki Sakai bike, branded Fåglum! It has a Miki Sakai-sticker and the serial-number M2C07685, which would make it a 1982. Dura Ace AX seatpost, steer and breaks. Gears and crankset are 600AX.

Gösta and Erik Fåglum, two out of the four brothers that dominated the Swedish cycling in the 1960's and 70's, supposedly put the wheels of the bike together. One of the brothers was a front-figure of some kind of the Mizutani-bikes (it was earlier called Seraph) in Sweden, for a short while. I read somewhere that he also ran a shop selling branded bikes but my clues kind of end there.

I can't add images in this post since I haven't posted ten times yet, but they are in the gallery bikeforums(dot)net/g/album/15021556
Any clues around this frame would be of great interest to me!

I also have my modified Koga Miyata RoadSpeed where the headbadge only says 'Miyata'. Serialnumber F510237, making it a 1977. I could find it in the 1978 catalogue. Any info on this frame is of course also welcome, even if it's not as big of an enigma to me as the Fåglum one.

Also, Thank you T-Mar! I have learnt so much by reading your posts and replies over the years and it has inspired me to find out even more about my bikes. Internet wouldn't be the same without you

Thank-you for the contributions. I know nothing of the Fåglum brand and only a little about the Fåglum Pettersson brothers and Mizutani. I know the four brothers were one of the top TT teams of the era and that Gosta won the Giro d'Italia in the early 1970s. Mizutani and the sister brand, Seraph, were both available in America during the early 1970s bicycle boom but had a relatively small presence. The company traces it roots back to 1924 and the factories were destroyed in the war. Circa 1947-1948 a new company was established and it still exists today, though the name has changed to an Anglicized version. The current company is primarily an importer and distributor of bicycles, parts and accessories, though they still offer the Seraph brand.

In America, Miki is best known as one of the contractors of the Centurion, Sekai and Specialized brands. During the period in question, they were considered one of the better Japanese contract manufacturers of mid-range and higher grade bicycles. I've seen quite a few early aero frames but offhand I can't recall one like this. Generally, the down and seat tubes are either aero along their full lengths or aero in the middle with round ends, to allow the use of standard lugs and clamp style front derailleurs. Your frame appears to have down and seat tubes that are aero at the top and middle but round at the bottom bracket end. If so, this is an interesting compromise that would result in both good aerodynamics and a stiff bottom bracket. I guess I shouldn't be surprised to see such a novel solution coming from a family of TT specialists!

While the Koga-Miyata may have a 1977 serial number, it is relatively high, so it could very well be a 1978 model manufactured in late 1977. The one thing I find interesting is that we have had some other submissions from Sweden that were Miyata and not Koga-Miyata. The bicycles didn't match the American Miyata models or the Koga-Miyata models. The owner was of the understanding that the there was a Swedish company designing and importing Miyata bicycles from Japan and not through Koga-Miyata. Of course, maybe I'm erroneous in assuming that you in Sweden based on the Fåglum.

Regardless, thank-you again for the submissions. I'll add Fåglum to the list. BTW, I saw what you did with your forum name.
