    Oldie but still good with Shimano 600 components

    Hi all,

    My old Nishiki "Comp" bike has Shimano 600 parts. The Okanagan is a lot more hilly than Southern Ontario and I'm a lot older than when I used to race back then.
    In short I'm looking for info on the chain rings 600 Wcut, the present set is 50/40. Is/was there a smaller size available that is a simple replacement?

    I'm guessing your crank is 130bcd given the age. You can put a 38 on there but that's as small as you can go. You can get a new crank & bottom bracket for well under $200.00 that can have a 34 or if you look for sub compact even smaller.

    Thanks,

    I'll have a closer look at that and figure out the ratios.

    Yes it is 130 bcd.
    The other question is what exactly does "Wcut" mean and what is different as far as performance goes?

    I have no idea what this 'Wcut' you're talking about is, I thought it was a typo.

    It means the teeth are uniform and not shaped at all. U cut would be more accurate. Pre-Superglide.

    In practical terms is mean old and not very good. Although I don't think it really matters on the small ring. And if it works good enough for you now with the big ring I suppose that doesn't matter either.

    Old is right but since it still works I'm "frugal" that's what it is.
    But after reading, reading and reading some more I just ordered a 30T 130 Sram ring.
    The black anodizing will probably clash with the glare of the large Shimano ring.
    Next step could be replacing that 50T with a 46T. Time will tell.

    20 teeth is a big jump. A 16 tooth jump works well on modern drivetrains, but will probably not work very well on mix and match rings. Your existing front derailleur could be problematic too.

    Not sure how you can get a 30T/130mm ring. The smallest ring you can physically fit on a 130mm bolt circle ring is 38T. It's either a 110mm ring, or a smaller ring for a triple.

    No, you didn't. Doesn't exist.

    Not sure that's possible with the 30 ring but hey. I did something similar with gear from the same era back in the day. I was preparing to do the Tour of Strongland back in the early 90's & the course profile is extremely hilly/mountainous with long climbs. I didn't have any gearing for that as all I had was suited for crits.

    I was running 52/42 on a Suntour Superbe Pro drivetrain. I think I bought either TA or Stronglight 38 ring. On the stand it shifted fine but once on the road it never shifted right & would drop/jam the chain more often than not. Because of the vintage of your bike & the cost involved, replacing the entire drivetrain is an option that would give you the best shifting possible on par with modern bikes but involve the most work & expense.

    Since cost is your main objective, your best option is to look for a much smaller crankset. Try to find a cyclocross crank with gearing of 46/34 or such. You'll probably have to replace the bottom bracket as well & while you're at it you might as well replace the cassette & chain too to give you a better range of gears. With equipment that old you can't just replace one thing only because it has worn in together. This is the least expensive option & you would be able to use the existing derailleurs. With the quarantine, Allieexpress is your friend for deals.

    Well it exists on Amazon.ca.
    Complete with a recommendation to get the 46T 130 to go with it.

    As always: seeing is believing, if it doesn't fit it simply goes back.

    No, it's not possible. The teeth would be in the middle of the bolt circle. Provide a link, I have to see this.

    If seeing is believing then take a look at this picture of a 30t ring with 104 BCD and you should see and believe how a bigger BCD is not possible: https://www.wolftoothcomponents.com/...ant=3647675653

    You're definitely looking at a misprint or not understanding correctly what it being sold.

    Well, after the information I got on the forum and a bit of additional research I found this

    https://www.amazon.ca/gp/product/B004YWGW9S/ref=ppx_yo_dt_b_asin_title_o04_s00?ie=UTF8&psc=1


    As far as I can see yes, I'm wearing glasses size 130x38T should fit the bill.

    That is, if this as a Sram ring and not a scam ring.

    The extra "insurance":
    <Ships from and sold by Amazon.ca.>, so far I have yet to have a problem when that applies.
    Not living in the big smokes, with fewer local sources, does have one big advantage: cleaner climate and all the scenery one can handle.
    Speaking of which; our Provincial Park will re-open tomorrow,
    and neighbours report a mother bear with two cubs in our neighbourhood. That and the obligatory "rattlers" will make re-opening for some a bit of a "challenge".
    More than 2 meters of social distancing recommended in both instances.
    Cheers

    OK the second chain ring arrived today. The parts fit perfectly!
    Looks? Doesn't come into the equation.

    Minor adjustment of the derailleur required, also have to find a replacement screw/nut assembly. There's always one or the other part that gives out after only .....39 years
    Perhaps a new chain would/could be in order.
    Other than that, ready to tackle the hills gradually.

    PS the local situation: slowly getting back to the new normal e.g. I got a haircut (two weeks back) which was overdue.
    The Traffic in the park and on the roads is thankfully still less than normal.
    OTOH the traffic on our RailTrail flat 28k with hardly any undulations is super busy on the weekend. I restrict time trial training on the MTB to the five other days.

    FC-6206 Shimano 600 was a triple with 110 bolt circle with a 50 outer and 38 inner (or 36 biopace, and then a 26 tooth granny ring....The rare FC-6210 was a 110mm double with 48 outer and 36 (or 34) inner.
    The model number of the crank should be stamped on the inside of one of the arms....
    If your opinion differs from mine, ..........Too bad.

    Buying parts to hang on your bike is always easier than getting fit.

    If you feel wimpy and weak, get out and train more, ya wee lassie!

    Honestly, those Shimano numbers/designations don't mean anything to me. But I know that, with the new 46/38 combo, climbing hills has become easier. It isn't quite "spinning" on my test loop, but a lot better.
    Even SWMBO, she's the stickler when it comes to aesthetics, has seen the light i.e. it works and makes "things" easier.

    You're going to want to lower that front derailleur a bunch, it's wayyyyyyy too high now that you have installed smaller chainrings.

    Yes, I did already.
    Applied some "Epic Ride", shifts like ..... very nicely.
    If it doesn't rain, time for that 25K loop with the "nice hills".

    Only thing missing is that one nut/screw assembly. A set of five is ordered, surprisingly from a Canadian source.

    Used to have a bike with 600 components... sooo nice. The same bike is somewhere in the Falcon thread.
    Do you have the SIS levers or friction?
