You could start your own thread here in C&V; the wrenchies here know a LOT about bikes of your vintage.

Good news about the stem. You did observe the limit line on it, right? And yes, drop bars are quite a different world, if your experience is mostly with uprights. Nice thing about the trainer is, you can sit up, exercise your back, etc., all without breaking cadence.

...probably not the best forum for such questions. Just sayin' . I don't want to say anything bad about the road forum, so I won't say anything at all about the road forum. Thumper's mom had some good advice there.

I worked with Omar at Oasis Custom Cycles in Phoenix, AZ to repaint my 1985 Maruishi Record (see above for original coral pink build). Once it was stripped down it became clear the 1985 frameset and the 1986 frameset are not the same (there's a link floating around among these forums to a review of the 1986 version)--the 1985 is definitely seamless double-butted 022, whereas the 1986 has been written up as seamed, quad-butted 022.

Anyway, Omar brazed on front and rear eyelets for racks/fenders, and painted it a metallic coffee brown that reminds me of the 1981 Trek 600s. Decals from velocals. Rebuilt it how I want to ride it (I've never been one for an 'authentic' rebuild--e.g., this now has a late 80s xt rear derailleur with a 12-32 cassette), and it'll be with me this Spring 2021 at Eroica California.

Would you have any information on a 1983-85 Maruishi Professional SPR? I have a pearl white 54 cm frame and fork I would like to try to restore. Most of the components that came with the bike are from 1983. Also have serial number. Any information would be great thanks.

I've been working on a few projects these past few months. This one in particular began many years ago with Suntour components, as I had a boatload of hoarded Cyclone and Superbe bits.

When I received the frame/fork in 2006, the only indication of an assigned group to this model was a Dura Ace crown race with the date code KK (November '86). Shimano EF dropouts are date coded KG (July '86). It was an easy decision to go with the 7400 group.

Some of the parts I sourced from a fellow forum member, others from ebay.

I've not seen anything online. The brochure I used to post the one pic is all I have. I too wish there was more info available.

First road bike purchase!

Just recently picked up a road bike for the first time. Been riding on MTBs for the better part of my life, realized none of my friends were into it and would rather ride road, so found a used Maruishi 'aerolite' for sale.
unfortunately, I could not find any information on it online, and I also cannot post pictures here for you all to see.

Any information you all have regarding the 'Aerolite' would be greatly appreciated.
I assume all components on the bike are original, and came with the following:
- Shimano 105 groupset
- Shimano Biopace oval chainring 2x
- Laprade seatpost
- Black Nitto quill stem

Sounds like a very decent ride. You can get around the newbie photo block by uploading photos onto your album, and then someone can do a picture assist.

This color was called "Metallic Rose". I had one that I bought from the shop I worked at in 1986(pretty sure). I used to race it back then!
The shop I worked at as a teen in the mid-late 80's sold Maruishi and Motobecane. I always tried to grab a Maruishi when it was time to build the next bike. The Motobecanes were absolute crap! We all hated assembling them because it took so long to get them working halfway decent.
The Maruishi bikes went together so easily and quickly. Never found any empty cigarette packs thrown in the box with the bikes from Maruishi!

Hello my friends) Maruishi Roadace before/after some upgrade. I bought this bike a month ago. I would like to know more about this model, may be you know: year of manufacture, riding style, why three oval chainrings in front, and something else interesting. Thanks) Photo in my albums in profile.

Welcome to the forum. This is a very interesting bicycle. The serial number indcates 1977 or 1987 manufacture and late enough in the year that it could be a 1978 or 1988 model. The derailleur cable routing over the bottom bracket shell would be more typical of 1977/1978 but the logo style, presence of a set of bottle bosses and areo triple crankset point towards the latter.

The bicycle would appear to be an Asian market model based on the lamp bracket mounted on the right fork blade and the fork crown mounts for the front rack. As for its intended purpose, the fenders, rack and lighting system mounts suggest it's a city bicycle, intended for commuting, running errands and light exercise, primarily in urban regions, while the components are indicative of an entry level model.

I'm not sure if the handlebars and saddle are original. Brake safety levers had largely fallen out of use by this time and it was more common to see this style of bicycle with flat handleabrs and less racy saddle, at least in North America

Most interesting to me is the Light Action Positron derailleur system. To the best of my knowledge, we never saw these in North America. Shimano introduced Light Action for the 1984 model year but I thought Positron was replaced by SIS in the late 1980s, with Light Action receiving SIS as early as 1986. Yet the rear derailleur has a blind P-pivot, which Shimano didn't introduce on other derailleurs until 1987. To this end, I'd be very interested in knowing the derailleur date codes, which should be located on the back of inside parellogram arm for the rear derailleur and the back of the inside cage plate for the front derailleur. The format is a double letter (see attached example). Selected photo assist...

You won't be able to add photos until you hit a certain number of posts.

The date code LK confirms 1987 over 1977, just as T-mar surmised. Late '87, so possibly even a 1988 model.

Thank-you for taking the time to check the date codes. While the date code for the rear derailleur is missing a character, the front derailleur was manufactured in November 1987. The timeframe corresponds with the serial number and confirms that it is almost certainly a 1988 model year bicycle that was manufactured in very late 1987.


I did manage to find an instruction sheet for these NP-41 derailleurs with an October 1986 date, so they appear to have been introduced for the 1987 model year, which is consistent with blind P-pivot feature. The instructions are printed in Japanese, supporting the possibility that they may have been available only in the Japanese and surrounding markets, and explaining why they are not included in the American market catalogues of the era. It's enlightening to know that Shimano continued to offer Positron after the introduction of SIS. It would appear that Positron had a much better acceptance in some markets outside North America, where its reputation is poor, though I personally found it to perform as claimed.
