Help with Nishiki Olympic

Hi everyone,

I'm new to the forums (and to biking) but I've been reading your posts trying to build up my knowledge. I bought a Nishiki Olympic and I'm trying to get more information about it (mainly the date). I tried dating the components but it hasn't worked out...the Shimano rear derailer has this number: L523 VIA and front has 2204 VIA. I looked under the bottom bracket for the serial number and not sure which one it is. I see:

C 68
G0886 or G0386 (can't make it out)
6127558

Cranks are Sugino VP, Shimano Light Action derailers, 6 speed cassette, SR seat post, Specialized stem, front rim is Araya, rear is a generic replacement, diacompe brakes and levers, headset is Tange Seiki Levin No. NL 500. Thanks everyone!

The 6-speed freewheel, low-flange hubs, and sidepull brakes suggest early 1980s, when the Olympic had morphed into a pretty decent bike. The original early 1970s Olympic was a heavy affair, with steel rims, cottered crankset, and very thickwalled frame tubing.

Try looking at the derailers again. Look for a small, two letter combination. I'm guessing the first of the two letters will be an f, g, h, i, or j. When you find that date code, compare it to the letters for Shimano component date codes here:
http://www.vintage-trek.com/component_dates.htm
If the month code is high, like Sept. to Dec. add one year to the year code. That will be a good estimate of the correct date. Or wait for T-Mar to read your thread and he should be able to nail it.

Ah, I see an HL between the limit stop screws which would make it 1983/84?

I bet you say that to all the Nishikis. = )

I took it to the LBS for a repair estimate (the chainrings are bent) and they said the spider is also bent. They recommended replacing the cranks, chainrings, cassette, and chain so it'll cost around $150 and I had paid $130 for the bike. Perhaps I can find cheaper parts on Ebay... I was debating whether or not to get a new bike and they tempted me with a Raleigh Grand Sport or a new Bianchi they had built using a kit (both bikes were around $650-750). I would hate giving up my Nishiki and I don't have room for 2 bikes but I'm wondering if the Nishiki is worth fixing up. I mainly go on shorter rides (15 miles or so) but I'm looking to go on longer ones.

The H & L between the travel adjustment screws are the identifiers for the "high" and "low" screws. The Light Action 523 rear deraileur was introduced in 1986. The 1987 model was actually designated an Olympic 12 and used the L525 rear derailleur, so this would appear to be a 1986 model.

Doh! I really need to start reading more post to brush up on my knowledge. Thanks very much for the help.

I have too many cranks and chainrings... and if you wait in line behind the other items I have awaiting shipping, I can send something out to you for cost of shipping... Do you want a triple or a double? I'll let you know what I have available... You may have to use your own chainring bolts and other hardware, but I even have a couple of old bottom brackets...

Also, you probably have a freewheel and not a cassette... If so, would you like a 5 or 6 speed? I have a couple of those I'll never use either. I may even have a 7 speed if someone who was asking about it doesn't get back to me. Need anything else?

BTW - for those of you awaiting shipping, as soon as I finish studying for Friday's test, I will get everything ready for shipping... really!!!!

Chainrings, derailleur and levers... you all know who you are. If I missed anyone, send me a reminder

You are too kind! I really appreciate this especially since I'm a poor graduate student/English teacher. I'll send you a private message soon and I can't wait to fix up this bike.

You should be able to rebuild your driveline using eBay parts, and as you have seen in LD's post, many of us here on BF C&V have stashes of parts, including some surplus to sell or donate.
