    84 Bianchi Limited?

    Cleaned and pretty much rebuilt.
    I originally posted this as an 89 because thatís what the seller told me. Since then, Iíve had a chance to date the complete Shimano 600 6207 group as having been manufactured in Sep. 83. So, Iím calling it an 84. T-Mar thought it was a Limited, and Iíve since seen photos of another Limited that confirm this to my satisfaction.

    There is some evidence that it is an Italian made frame. Although, it appears to be a mid-level at best. There is no decal indicating the type of tubing.

    I was able to rebuild the rear hub, headset, and pedals that felt a little like spreading peanut butter. It is obvious to me that the grease is original as well. Makes me wonder how the bikes sold today will look in 25 years. What I like most about this bike is that Iím pretty convinced that this is the same bike that rolled off the showroom floor in 84, except for the following items that I changed:

    Bar tape, cables, pedal straps, brake hoods, tires.

    Iíve just ridden it around the neighborhood to make sure everything works. It rides nice, and fits me really well, so I think Iíll keep it for awhile. If I were to sell it, what would be the West Coast selling price?

    Agreeing with miamijim, for you to get that would be plenty. I followed you through this bike process and know all about the market phenomenon. Celeste mid-level, mid-80s, decent shape Bianchis go for about the range, on a good day one hundred more on e-bay to those who don't know any better; suggested and confirmed to be Italian made for what difference that makes.

    If I recall correctly, the frame dates to 1985 and it has Italian theading in the BB. This was just about the time the Italians were pulling back maufacture of the mid-range models to Italy, due to the drastic change in the Yen. New 600EX is appropriate for a Limited of the period and tubing was Bianchi Special by Columbus. This was a butted tubeset and almost certainly Marix/Cromor. Original price was $520 US.

    I'm not familiar with west coast pricing, but from what I hear,it is very high. If it were celeste, it would be worth even more.

    Not that it matters, but you keep saying it has 600EX. My understanding is that the "EX" was an improvement over the standard 600 and I believe is denoted by the 6208 model #. This is the 6207 group. Everything else sounds about right. Thanks.

    A question I forgot to ask. When dating a bike by it's components, how much of a time-lag do you usually allow? In this case, the manufacturing stamps dated to Sep 83. Allowing for shipping of the parts, the building of the bike, etc; would you allow 6 months or more for the actual dating of the entire bike?

    Shimano used 600EX to refer to the 2nd generation 600 group. 600EX had 62xx series part numbers, where the 6 refers the group and the 2 to the generation. While refering to your components as 600EX would be corrrect, I don't believe I've ever done so. I believe I've always refered to them as New 600EX, as that is what they were orignally introduced as in 1984 and has become common terminology to distinguish it from the older and cosmetically different 600EX, which is commonly referred to as Arabesque 600EX.

    6208 was simply the part number series used for the upgraded New 600EX components introduced in 1986 such as the indexed rear derailleur, shifters and freewheel. Parts which were not up-graded in 1986, such as the crankset, front derailleur and pedals retained the 6207 series of numbers. Both were 600EX or New 600EX, if you prefer.

    For reference, here's the vintage Shimano 600 timeline and designations:

    Shimano 600
    1st generation
    1975-1980
    Designated with various 3 digit numbers originally, but redesignated as series 61xx circa 1980.

    Shimano 600EX
    2nd generation
    1978-1987
    series 62xx
    sub-series 1978-1983 (a.k.a Arabesque 600)
    sub-series 1984-1987 (a.k.a. New 600EX, sometimes refered to as 3rd generation)

    Shimano 600AX (a.k.a. aero 600 )
    3rd generation
    1981-1983
    seriess 63xx

    Shimano 600 Ultegra (a.k.a. tricolor 600)
    4th generation (sometimes refered to as 5th generation)
    1988-1997
    series 64xx

    You'll notice that 600EX ran concurrent with 600AX and that New 600EX retains the same 6200 part number series. Clearly, Shimano considered New 600EX to be a continuing development of 600EX and not a new generation. However, it would appear that Shimano had 2nd thoughts about this, as when they introduced New Dura-Ace in 1985, it was clearly styled on New 600EX, yet received a new 74xx series designation, to distinguish it from Dura Ace EX, which was 73xx series. Consequently, you'll sometimes see New 600EX referred to as 3rd gneration and 600 Ultegra as 5th generation, though technically they are 2nd and 4th generation by virtue of the 2nd number in their series designations.

    Unfortunately, Shimano's series designations are not 100% consistent, sometimes leading to confusion. Sorry if I've confused you in trying to explain it. However, the bottom line is that your components (and any components designated 62xx) are techically 2nd generation 600EX, though those for 1984-1987 are commonly refered to as New 600EX.

    Components manufactured in September 1983 would generally be for the 1984 model year. Typically, the product for the next model year starts manufacture about September. However, there is no hard and fast rule, it could vary either way by a couple of months.

    Also, in the case of components they can sometimes be much older than the bicycle. This is generally due to poor stock rotation. Obviously, you need a new shipment of parts before you use up all your existing stock. Sometimes, the new shipment gets placed on the shelves in front of older strock, delaying it's use. If this happens for several shipments, the product being pushed to the back can be quite old before it get used. To prevent this, most manufacturers use a system called FIFO (First In, First Out) meaning that new stock gets placed behind old stock, so that the old stock gets used first.

    In your case, the problem is complicated by the fact that production of this model was transfered from Japan, back to Italy. It's quite possible the parts were from shipped from the original Japanese manufacturer and not Shimano. This may have caused additional delays and may account for 1983 coded components on a frame that is clearly 1985 manufacture.
