Dave,
Dave Mayer said:I have stumbled across a lifetime supply of NOS Mavic road components and spare parts. Vintage I
would guess to be late 80's. Headsets, freewheel hubs, and derailleurs. Help would be appreciated:
What a nice find! These are cool parts. I have a Schwinn Paramount set up with most of this group.

Does the Mavic 840 rear derailleur index well with Shimano 7-speed stuff?
The Mavic technical reference for the 840 claims it will work with "evenly spaced six, seven and
eight speed freewheels". I find the 840 works pretty well set up for 8 speed Shimano spacing. While
I have heard folks come up with lots of different anecdotal ways of arranging the cable and plastic
cable guide to shift clamp, to shift other spacing, I have only had success shifting 8 speed Shimano
gears and using the guide said toward the crankset. That said, I have only tried with the 821
indexed shifters and Sachs Ergo shifters.
Quoted message said:I've read in Usenet that it works - but I've also got a new Ultegra unit, and is there really any
point in installing the Mavic if the shifting simply isn't as good?
The Mavic 840 had durability the Ultegra will never achieve. The Ultegra will shift more crisply
than the 840 and weighs a great deal less than the 840. If you are using STI, especially 9 speed,
don't bother with the Mavic. If you are using 8 speed and like the cool look of the Mavic (and don't
mind the added weight), go for it! I love it!
Quoted message said:And how do I route the cable? Through or over the little plastic thingy? Looking through Usenet,
I've seen both as the correct answer.
According to the manual, if you are shifting 7 or 8 speed, turn the pivot down and pass the cable
around the outside of the pivot. I did not find this to be optimal for my 8 speed Dura Ace cassette.
I've tried both down and flat against the parallelogram extensively. If you are using 8 speed
indexing, with Mavic shifters, simply leave the plastic guide resting up against the parallelogram,
routing the cable around the underside of it and then up to the cable clamp. I find the shifting
flawless, despite what my manual says.

The matching front derailleurs are braze-on units that I have not seen before. It does not fit a
standard braze-on. Did Mavic produce a clamp fort these to fit a standard steel frame?
My manual does not cover this unit, though a few others in this forum seem to have a reasonable
answer to your question. I have used the standard Mavic 870 front double braze-on, with no problem
in a braze-on frame and a Shimano braze-on adapter.
