2038.0. "MIX AND MATCH INDEX SYSTEMS" by AKOCOA::FULLER () Tue Aug 13 1991 18:10

    I believe this will work, but rather than going through the pain if
    it doesn't...
    
    On my new tandem I am buying the new Suntour 7 speed cluster and
    indexed Suntour bar-end shifters.  I would like to use a Deore/Deore XT 
    derailleur, because it has a longer cage then the Suntour XT Pro.  
    Will it work?

2038.1Don't know, but...MAIL::ALBERTTue Aug 13 1991 19:0812
    I doubt it will work, but I have no personal experience to say for
    sure.  I know people who have had very little luck with mixing the
    reverse combination, with Shimano Hyperglide cluster and Suntour
    derailleur.
    
    BTW, Suntour makes both a long- and short-cage XC Pro rear derailleur.
    And you might try a Sachs/Maillard freewheel--they have profiled teeth,
    sort of like pseudo- Hyperglide.  They work great with Suntour indexed
    systems and you don't have to mess with Shimano freehubs, Hyperglide
    chains, etc.
    
     
2038.2You want strong components for a tandem...CTHQ2::FREREEllas Danzan SolasWed Aug 14 1991 15:366
    Word of warning:
    
    Sachs/Maillard freewheel may not survive for very long the stress
    caused on a tandem (I shared this experience in another note...)

2038.3STICKING WITH SUNTOURAKOCOA::FULLERWed Aug 14 1991 17:218
    re. 2 Advise well taken.  This is my reasn for buying Suntour. 
    
    I have heard that Suntour XC pro comes in both long and short cage, the
    one I saw at Nashbar seemed a bit smaller than Shimano...I am not sure
    if that was the longer or shorter version.  With a 28/44/54 12-28 that
    is a lot of chain wrap!

    The XC-Pro  rear  deraileur  from Nashbar is the short(er) cage. I
    have one, and it shifts very well, but I'd like the longer cage to
    get  a  little  more chain tension on my recumbent with the double
    length chain.

    The XC-Pro  rear  deraileur  controlled  by  a  Grip-Shift  is  an
    absolutely  fantastic  combination. You think about a shift and it
    happens.

2038.5Think twiceRUTILE::MACFADYENYou never listen to a word I sayMon Aug 26 1991 13:1513
    Re .0:
    
    I'd be very nervous about laying out the sort of money you're talking
    about if I wasn't sure a mixed system would work. Indexing requires
    that the gear levers, derailleur and block all work to the same
    spacing. Different systems must work to similar specs, but the same?...
    
    If you're convinced that a mixed system is what you want, you should do
    some more research. Haven't there been articles in the cycling press
    about this?

2038.6Didn't need to mix and match components after allAKOCOA::FULLERMon Aug 26 1991 15:189
    I found the long cage XC pro rear derailleur so no more problem.
    
    In addition, I just remembered that I did this exact thing to a
    friend's bike.  (My memory must be going bye bye) She was going to 
    bike around Mt Ranier as part of the LAW ride so she needed a triple.  
    I put my Deore XT leaving the suntour shifters and freewheel.  It worked 
    fine.

2038.7CSCOAC::HOOD_RMon Aug 26 1991 20:3617
    
    I've also mixed and matched before.... no problem. Freewheel gear 
    spacing is usually the same.. eyeball it. The problem comes in the
    shifter/derailleur.... shifters are set up to to pull a certain amount
    of cable-per-click and deraillers are set up to move a certain a 
    certain amount of distance-per-amount-of-cable. 
    If the shifters pull the same amount of cable per click, they are 
    interchangeable. If the derailler moves the same amount of distance 
    per amount of cable, they are interchangeable. If either is 
    off JUST A LITTLE, then you will get "pseudo" indexed shifting ( it 
    works pretty good, but never perfectly... it always seems to be 
    just a little off).  While some people like their index shifting to 
    be perfect, close is good enough for me.... I think this is why some
    people say "no way" and some people say "no problem".

2038.8Non-index shifter replacementRGB::SCOTTWed Sep 04 1991 11:2616

     I have a slightly different problem - a friend's derailleur gave up
  the ghost (the stop pin on the jockey cage sheared off). It was a
  low end Shimano component, non-indexed. We looked in the Nashbar,
  Performance, and Colorado Cyclist catalogs to find a replacement,
  but it seems that there aren't *any* non-indexed derailleurs available
  any more! So, the nearest choice seems to be either Shimano Exage or
  Deore with the long cage. Largest freewheel cog is 32, BTW.

    So, any advice, commentary, ideas? She wants to get this on the
  road soon, as this is century month. (We just finished a trip 
  between ABO and Denver - talk about training!!)

    A derailleur designed for indexing will work fine with non-indexed
    shifters,  so  choose  which  ever  one  strikes your fancy. Since
    you're  going  to  have  an  indexed derailleur, you might want to
    think  about  going  to  indexed  shifting  eventually,  so pick a
    deraileur  which will work with whichever indexed shift levers you
    want to go to.

    The next time you replace the freewheel, get new levers and you'll
    have indexed shifting.
