Full on "snob" apparently!

Genetically-enhanced Floyd Landis dopepower legs, methinks

Anyway, cross-chaining a Victory groupset for a picture automatically makes you humble

P.S.: Remember that guy who claims to know all the TdF mechanics and why disc brakes are now part of the peleton? That's the type of übersnob I'm talking about. That fellow would come into this thread and beat the fear of St. Tullio into your soul for cross-chaining - like there's nothing better for him to do

I have a Gitane Tour de France kitted out with a SX630 rear derailleur that indexes fine. Not great, but adequate. The SX630 is the all-metal variant of your SX610. Aside: I have used the SX610, and found it to be the shortest lived rear derailleur I have ever used, as the plastic derailleur parallelogram cage gets loose and sloppy real fast. The thin metal covering on the outside of the plastic bits is basically cosmetic.

Anyway, this is how you get the SX610 to index: start with some Campagnolo 9-speed Ergopower shifters - not the later ones with the round hoods, the earlier ones with the pointy hoods. Then you need a Suntour 7-speed freewheel, which features progressively thinner cog spacing as the cogs get bigger. I like the Winner Pro, particularly because you can customize the spacing.

Note that the SX series of Simplex derailleurs will not handle any cog larger than a 28 - even the long-cage variant of these derailleurs. Even a 28 is dodgy, and requires careful tuning of the tension of the 2 springs inside the derailleur body.

Finally, I recommend a modern 6/7/8 speed chain like Shimano HG or better IG. Vintage chains are hopeless.

Combine the above, and you have relatively decent 7 speed indexed shifting.

I had a tomassini with a victory derailleur. It was working as intended. I rarely notice performance differences in rear derailleurs though unless they're completely off.

Take 10 minutes to install and find out.
