    need pictures of rear derailer hanger clocking 71 supersport

    When I got my bike it had some cheap improper derailleur hanging off on the cable, Someone on here who was generous sent me the proper one for a 72 super sport, the issue I'm having, is the 72 had the derailleur inline with the rear axle, and mine has the integral forged hanger, the hanger plate wouldn't line up properly at all, I flipped the hanger plate over, and it seems to line up, but the derailleur doesn't seem to be tensioning my chain properly, the chain acts like it has too much slack and wants to skip teeth on the ring gear under high load, I've seen some pictures with the derailleur cogs at a different angle then mine, and I'm wondering if the plate is putting it at an improper angle, I'm trying to figure out to get the smart phone to take non blurry pictures, so as soon as I do I will post some, does someone have some good shots of the derailleur mounting on a 71 supersport? Maby they can help me figure this out, I also cant shift into the largest gear, no matter how many adjustments I make, the cogs look straight and inline,

    Pictures are worth thousands of words of explanation. Also, you may be able to find pictures on the "Classic & Vintage" forum, which describes your Schwinn Super Sport.

    A word of warning: I think your Super Sport has an unusual Huret dropout that is sometimes incompatible with "regular" derailleurs. It'll mess up good mechanics who aren't familiar with it.

    ugh. I remember HATING Huret Derailleurs with a passion, when they were on new low-end bikes in the late 60s, early 70s. in fact, pretty much any bike that had a Huret was, IMNSHO, a 'bicycle shaped object'. Even Simplex was better.

    This is the derailleur that it sounds like you have; if so you have figured out it's not the right one.

    ss.jpg

    During 1972 Schwinn changed from the Huret cast dropouts (with hanger) to the stamped out one above (no hanger). The below Schwinn Approved version of the Huret Allvit Super Touring derailleur (below thumb nail from Velobase.com)is what came with your frame with the Huret dropouts.

    The below thumbnail is the Huret derailleur of a similar design..

    Yes I have the Huret cast dropout, so apparently the one for the 72 isn't the proper one, what do I need to look for and what aftermarket derailleurs will work with this dropout?

    sorry for the confusion, it's a 71 Schwinn supersport, I guess some terms have changed over the years since I was into this stuff, when I say clocking I mean the angle of the plate that holds the derailleur when it's bolted to the bike, thats what I was always told it was called, things have changed so much in 20 years I guess

    Clocking was not used 20, or 30, or 40 years ago. Grammar and spelling have not changed either. I would suggest that others will tend to put as much effort into providing assistance as you put into constructing a clear post. It's quite easy to edit the post once it's up, and it's better to wait until you can use a computer, or at least to take more time, rather than to post a hard-to-read entry with a phone.

    I'm not on a phone, I was talking about fixing my phone so I can take pictures, I'm just trying to figure out what I can do to fix this issue so I can ride the bike and be able to shift gears, I've put a lot of time and effort into this as well as money, and I'm down to trying to figure out the proper derailleur. I am very appreciative of all the help I have received on this board, I wouldn't have been able to take this from a complete basket case, to a nice bike again, if I hadn't gotten all the help that I have.

    I assumed you were on a phone due to the lack of complete sentences, apostrophes and correct spelling. You cannot bolt a modern derailleur onto your Huret dropout - it lacks the stop that they depend on being present. You have to either saw off the hanger and use a derailleur with an integral hanger or find a vintage Huret compatible derailleur.

    Being the owner of 9 SSs and one 1972 Sports Tourer the cast forged drop out disappeared in the late 1971/early 1972 models and Schwinn went to standard for them Continental rear drop outs on SSs. The change was about the time the Sports Tourer came out which then because it was a better bike got the cast drop outs. There is a lot of differences between my earliest 1966 bike and my last 1973 model and they all have to do with making the bike cheaper. Roger

    Why saw it off? My '80s Diamondback MTB had a derailleur with an integrated hanger when I got it, despite having a hanger on the frame as well. I have no idea why. It worked fine. Do Huret hangers stick out unusually far?

    Although the OP's post is not clear on the point it appears that the hanger may be interfering with proper mounting of the hanger plate. Otherwise he should not have had a problem with properly mounting the derailleur.

    I was actually able to take the plate off of the 72, and flip it upside down, and it lines up properly, but the derailer still isn't tensioning the chain properly, I guess I'll have to search for the proper part, if I had one in my hand, I could see the difference and possibly be able to make modifications to a later derailleur and plate to work, this is probably the only part I wouldn't want original, at least from what I've heard about them. I'm a machinist and fabricator, I could make an entire plate if it came down to it.

    We still need a picture, a better explanation, or you need to take this to a mechanic for assistance. The plate can't be mounted "upside-down" - perhaps backwards but that apparently caused a new problem.

    Please use periods where appropriate - three missing in the short paragraph above. Also please think about how you would feel if you received something like the paragraph below as advice.

    I dont no if this is but the bscrew may need to be put in, or the h/l screws, so the tention is ok, and the chain if its more than 1/16 out a new one may be beter but high gear might not be so good, maybe its crooked to, but the round part doesnt have the right thing on the front so the whole thing goes forward.

    ...and I'm sorry if I seem a bit crabby, but I put a lot of effort into being clear when I offer assistance and I expect those wanting help to make the same effort. I also do not hesitate to suggest in-person assistance when warranted, which is why I suggest you get someone who can give you hands-on advice. There is no guarantee that you even have the right chain length, that you've routed the chain properly through the pulleys, or that you know how to properly mount the rear derailleur, let alone adjust it. That's a lot to cover in a forum.

    I understand, I dont have the option of an LBS here, the only one, the owner is partly retired and is almost never there. I do know how the derailleur is supposed to be mounted, and the chain is routed through the pulleys correctly, I can ride the bike, but the chain is loose, It's very possible that the chain is just worn out, but something doesn't look right about the derailleur angle . Can someone clarify what they mean by the stops? I think I know what you are talking about but I wanted to make sure, I love the bike by the way, I had one just like it when I was 18, and I put many miles on it, riding all over Northeast Ohio, Now when I'm 40 I'm able to save another one

    The hanger on your derailleur should look roughly like the one on the right below - or it may have no notches at all. It's been too long since I've seen one in person. You don't have to worry about stops if that's the case. There'e nothing to adjust in that regard. If the spring for the pulley is working, you threaded the chain through with it under tension, the derailleur is mounted correctly, and the chain is the right length then the derailleur will assume the correct. If you check either Park or Sheldon sites regarding derailleur adjustment and chain sizing you should be able to determine the problem. position in each gear.

    p.s. as for monitors, very good CRT monitors can be had for a song these days with everyone going for LCD types. I had a struggle selling a very nice HP 17" crt monitor for $25.

    ok, that angle looks OK. when you shift to the smallest sprockets, does the lower cage move all the way back til its almost horizontal, or does it stop somewhere before that

    can you show us a picture including the rear sprocket cluster and chain rings with it in the gear position that has slack and is skipping ?

    Unfortunately you are not giving us much more information in pics than in words. The gearing is a system, and one has to address any problems on it as such. Just as you can't machine a part until you know something about its function, how much stress it has to bear and what it interacts with, we need to see the parts that the derailleur interacts with, meaning the freewheel, and we need to see it in the state that it's in when you are concerned, meaning when you think the chain is too slack.

    Also you need to read about not just the chain, but also the derailleurs and freewheel, so that you understand how they work together - and wear together. Odds are high that when you replace the chain you will need to replace the freewheel as well. Both need specialized tools, which means significantly more money for parts and either shop labor or tools.
    There's no such thing as a routine repair.

    Don't tell me what "should" be - either it is, it isn't, or do something about it.
