Good new derailer for shimano 6/7 speed freewheel

Whats a decent RD for a shimano 6 or 7 speed 14-28 freewheel?

Would Sora or Tiagra work?

Friction shifting? Sure.

Yes - those will work fine with indexed-shifters - IF you have a cassette that will work with such.

Its for a either 6 or 7 speed freewheel. Is the only difference between 6 and 7 speed freewheels One cog?

No- the spacing between cogs on a 7-speed freewheel is usually narrower than a 6-speed freewheel. That is, unless we're talking about old-school Suntour Ultra freewheels- but those almost predate the modern indexing shifting systems.

A decent derailleur for what? Indexed shifting? Any one of the Shimano derailleurs in current production. But you need to factor in the 'freewheel' you are talking about. If it's an older one, then it's not built to accept the exacting tolerances needed for this action. So you'd need to tell us what is actually on your rear hub. Or at least take a few photos and post them here for us to figure out for you.

Ideally you'd have a rear wheel with a cassette. This would ensure it was ready for indexed-shifting with the proper shifters, of course. If you have an older freewheel, I'd suggest going for friction-shifting. Or you'll need a new wheel set up for accepting a modern cassette instead of a freewheel.

I use indexed-shifting on my hybrid. On my vintage PUCH racing machine, I use friction-shifters - Campagnolo to be specific. I could, but wouldn't, have it set up for indexed-shifters. I like to feel it shift through my fingers and ears, working in tandem, as I run down insect-people on carbon-bikes that they have no idea of how to ride.

Im about to get this Schwinn Traveler-12 speed-4130-in my size. Which I believe has an index quill stem shifter.

But Im pretty dead set on building up a solid axle (nutted) freewheel type rear wheel (Spaced to 125, and being nutted, ill be able to add spacers?). And get a shimano 12-notch freewheel.

So whats better then tourney, but should work on a brand new shimano freewheel?

Currently I don't own any freewheel tools, so i figure a good one would be the twelve notch.

to be honest I dont think a tourney derailure will work with the indexed stem shifters.in my experience any way. If you can find a " light action " derailure of that period that is what was on many of them in that era. Other than that any shimano modern era derailure will work, I would suggest at least 105. as far as what will work with what its more the shiftr has to match the freewheel or cassette than the derailure.

Hold your horses, Pisano. You were asking about compatible derailleurs. Now you want to paint a 12-speed Schwinn? Rather than confusing the spleen out of future readers using the Search feature here, may I suggest YOU use the Search function regards paint jobs/$$$? Read: Stick to the original topic, okay?

Let me explain this to you: Early forms of indexed-shifting were wildly CRAPPY. Some worked. Some didn't work. Some were chased into the streets and beaten to death with a hammer. My suggestion is to go with friction-shifters for older bikes that take freewheels. Pre-cassette bikes. Unless you are planning to publish a book with "What Worked, What Didn't" in the title. In other words, it's a losing proposition. The only way I'd approach this would be to build a new drive-train using a modern hub made for cassettes. Friction will free you up from spending a fortune, and shift equally well as a modern indexed beast.

A Shimano Sora will be more than adequate for a task of this nature. Or virtually any other modern rear-derailleur. This said and done - we haven't even touched the subject of a front-derailleur that will work with an older bike with a new indexed-shifter. Personally for my road-bike I prefer friction-shifters. I use a Campagnolo Nuovo Record FD (front-derailleur) and a Shimano Ultegra RD on my road-machine. Installing an indexed-shifter on this miscegenation of components would be laughable. Friction will set you free to use whatever components you please.

Last Words Dept. - Do what you want.

Ive currently got a tourney-7 speed freewheel- alivio sti shifter working together on a cruiser bike. SO the tourney does index.

Does any body have an online resource to the cheapest bar end shifters? Googling it, jenson has 8 speed for 55 and 9 speed for 66. And Veloorange has friction for 60. Are there any other options in the same price rangE?

Before we let this thread fade away in to the archives.

True or False: A Brand new 9 speed rated shimano derailer will work with a Brand new 6/7 Speed shimano freewheel in friction mode?

P.S, the reason why Im up at 5:00 a.m is because I work at 6.00

I have this rear derailleur on my old 6 speed Univega road bike. It shifts fine.

At 40 bucks, it's a killer deal.

True ...Almost all derailleurs will work with all freewheels in friction mode. Just make sure the derailleur can handle the freewheel range. Meaning you need a long cage derailleur for wide range freewheels such as 13-32 to handle the extra chain.

True. And in index as well most likely. I run a 9spd Deore RD on both my hybrid and MTB with 7spd cassettes and index shifting.
