672.0. "Screwed by Shimano!" by HPSRAD::ROSKILL (The Central Scrutinizer) Tue May 17 1988 13:11


        I recently acquired a set of training wheels, and in order to
keep them compatiable with my Shimano 600EX SIS ('87) system, and for
ease of swaping, I went out to buy a new 600EX freewheel.  Both Nashbar
and Performance sold these last year for about $17.00.  Neither company's
new catalog has this item having replaced it with the 600 Ultegra ( a 
cassette freewheel system - not compatiable with my wheels, or last years
600), they only have the Durace ($39.00).

        So I call them up figuring they probably have some around for people
like me; Wrong!  They both tell me the only one they sell that I can use
is the Durace.

        I call up some local bike stores and they have them in stock, but
want, guess what, $39.00 for a 600EX freewheel ( A good investment with
return on equity in excess of 100%!).

        So now I am stuck either paying big bucks for either?  Any one
know a place that has 600EX freewheels for a reasonable price?

Oh yeah Performance told me that Shimano frequently changes their product
line in order to put customers in the position I am in.

    	OK, what's SOOooo spechul about 600EX freewheels ? (dare I ask ?)

    Why not a  "regular"  Regina ?   Isn't cog to cog spacing standard,
    or does clickety click shift demand it's own spacing ?

Yeah the whole SIS system works together, Shifter, Freewheel, and Rear Der.
Can't just use and freewheel.

The good news is that Colorado Cycle has them for $20.00, Stock up 
while you can.

672.3"Good" news would be to go regular for real cheap....MENTOR::REGMay Be ('til June 1st)Tue May 17 1988 20:217
    re .2	I can see why the shifter and rear derailleur have to
    match, indexing detents etc., but I still can't see why you can't
    put a std clutter on there.

672.4just an observationRANGLY::PFISTER_ROBBike hard, or sell itWed May 18 1988 16:289
I dont know the EXACT reason why Shimano SIS demands it's own freewheel,
but if you look at the teeth on the Shimano freewheel, they seem to be
bent slightly off axis compared to `normal' freewheel....

I only own SIS on my mountain bike on which I have a high turnover rate 
on chains, freewheels, and deraillers. (read: nothing has lasted long enough 
to really worry about future compatability)

672.5Article on index shiftingCCYLON::SCHULDTLarry Schuldt - WA9TAHThu May 19 1988 15:1610
    A couple months ago Bicycling magazine had a technical article on
    indexed shifting.  The author measured the cable movement for each
    type of indexed shifting (different Shimanos, Suntours, Synchro,
    etc.) and plotted this on a graph.  Result was to show clearly that
    the spacing between gears is not constant.  Each manufacturer uses
    a different amount of cable movement between gears.  However, Shimano
    is compatible between different Shimano lines.  In other words,
    a light action (L series) 6-speed is compatible with Shimano 600
    6-speed which is also compatible with Dura-Ace 6 speed.  I beleive
    that all Shimano 7-speeds were compatible, too.....

    Performance and Nashbar no longer list Non-Hyperglide,
    7-speed cogs for Dura-Ace cassette freehubs.
    
    Has Shimano stopped manufacturing them?

672.8Colorado Cyclist has Dura-Ace 7 -spd FWZEKE::SZCZThu Jul 15 1993 13:1010
    Colorado Cyclist (1-800-688-8600) has a Dura-Ace 7-speed Freewheel 
    listed for $59.99. It does not say whether its Hyperglide or not.  
    All the cassettes listed are Hyperglide.
    
    I just put a Sachs-Mallaird ARIS 7 speed freewheel on my bike and it
    works great.  They are advertised to work with most index-shift systems
    such as Mavic, SunTour, Shimano, Sachs, and Campy. Nashbar and
    Performance carry them as did my local bike shop.
