What is the best 7 speed freewheel

What is the best 7 speed Shimano compatible freewheel in this day and age??
If any...........???
Performance sells Sun Race. I see then available awfully cheap.
Shimano freewheels are inexpensive as well.
IRD has the expensive end covered, but way much so...like 3X the $$$ of the other 2.

I know there ate those who swear that the Suntour freewheels are the best, but I have Shimano shifting stuff.

IF I used freewheels, I'd consider them a "consumable" and get the one that gives me the gear combination I want.
That said, I'd prefer the Shimano.
Suntour's obsolete. Nothing wrong with them, but finding one in good condition for a good price might be problematic.

The cheap Shimanos shift just fine. I am running one on my commuter. It works well and it was cheap. The best were the Sachs 7 speed freewheels.

+1) consider them consumable like cassettes .. the Hyperglide tooth patters seems widespread

friction shifting .. I liked the old tooth style better, because it didn't ghost shift ,
if I didnt get the RD right under the cog.


But time marches on ..

Sun tours New Winner Pro Bodies were great , I have a box of old bodies and some new cogs ,
even got a purge fitting made they have a lube port covered by the hub whhen you screw it on

My machinist father (1920-2000) made a way to push oil thru the hole
with a zirk in a threaded like the hub piece of steel ..

The 7-speed 14-28 Shimano Tourney freewheel that I bought was improperly spaced, so wouldn't work for indexed shifting. Not sure if it was a fluke or not.

Sachs are the best, you can still find them on Ebay if you are persistent.
What cog ratios are you looking for, just the 13-28 ?

13-28 would be fine, or 13-32.
Dunno if the Sachs would work with Shimano indexing (I've gotten lazy in my old age...) ??

Ron, I'm no freewheel expert by a long shot, but if you're going SIS I'd choose a Shimano freewheel like this one: http://www.biketiresdirect.com/produ...Fatj7AodmwcAaA .

Yep; it was designed to do this.

I thought Sachs (by far my fave for friction) were designed for the ARIS system. Do ARIS and the Shimano systems have the same cog pitch?

Yes , the Sachs FW's are Shimano Indexing . There is a trade off with the newer FW and casettes as opposed to the older ones. The newer cog is shaved/shaped considerablly to "aid" shifting . I use quotes as this is entirely subjective as to needing any "aid" at all ! The Sachs cogs have a comparitively tiny portion of the tip shaved, and that is it. The plus of this, is that the fuller Cogs last a very Good Long time So while others are replacing their cassettes and Shimano/IRD FW's, the good ol' Sachs and Sun Tour cogs just keep on a truckin'

If you're used to or expecting a certain type of feel to your shifting, the Sachs may not be a best choice. I cannot say, as I do not use index shifting. I know they will work of course, but compared to a new FW with the shaved/shaped cogs , I suspect it may not feel as smooth. But, all things being relative, it depends on the expectations of the rider .

Probably IRD but at their prices I've never tried one. I don't like Shimano's tooth spacing so I geneally use SunRace (usually 13-28).

You can still find NOS Shimano Dura-Ace freewheels on Ebay. They're around $150 if you want to empty your wallet. Used ones are all over the place.

These have the Uniglide tooth shape. Later Hyperglide freewheels definitely work better.

I've read a few online anecdotes about early and sudden IRD engagement failure. This, coupled with the price, has been enough to keep me from buying one. Basically, I can't say that I hae any empirical input on IRD freewheels, but their rep doesn't seem to align with their price.

I'e been toying with the idea of getting a DNP freewheel, due to the increased top-end offered by an 11t cog. However, the fact that i don't need such a high ratio, plus a slightly higher price, has led me to stick to the shimano/sunrace offerings. Good enough + cheap enough = winner.

I still can't figure out why freewheels cost less than cassettes.

The best 7-speed freewheel is the one in the dustbin of history. The Shimano cassette system is so much better. But if you like bending axles...

Get a Shimano or SRAM (same as Sachs? recommended above.) I'd avoid the cheaper Sunrace or whatever, as I've seen some of them self destruct and freewheel in both directions.

Bending axles was not as big a problem with 126mm spacing as it was with 130mm. Going with a 7 spd shimano cassette is not a bad idea, though. Hub parts are readily available for shimano hubs and 7 speed cassettes are also readily available (not quite yet in the dustbin of history): http://www.amazon.com/Shimano-HG50-7.../dp/B00393913M

The unsupported axle length on the right side is exactly the same regardless of frame spacing.

I have multiples of Dura-Ace, Winner, Winner Pro, Sachs and Shimano HG37 And TZ21.

Dura-Ace has the best construction and the best cog longevity but features primitive Uniglide cogs. Sachs cogs wear quickly, but most can be flipped with a little grinding. My vote goes to the TZ21. Cheap, superior Hyperglide shifting, and the lightest of the bunch. Remember that freewheels only rotate when there is no pressure on the bearings. So the precise, expensive construction of Dura-Ace is overkill.

I was thinking of what happened with 8 speed freewheels and 130 mm rear; that's when the problem became more acute.

Why I liked my Phil wood Freewheel hub .. I got a 48 hole hubshell ,
and built a touring wheel set around it
and a SBI 40 hole front. several long tours ,

built another set with a Bullseye hubset next. still use that one.

More proof 11t cogs are stupid (not that you'll find one on a freewheel):

New Sunrace 11-28 or whatever, plus a new YBN chain = skipping on the 11t.

Epic fail. Presumably it's Sunrace's fault not YBN's... doesn't really bode too well for their other stuff IMO.

There are freewheels with 11t cogs. Also, Sunrace has been around for 40 years. Not sure how that "bodes" for them....

I agree that having a 12t high-cog versus an 11t is a better idea...

Supposedly the pawl engagement problems have been corrected in the MKIII version of the IRD. I have one and will try it.

Bending axles has never been an issue with PW hubs.
However, I also have wheels built on early Specialized sealed bearing hubs, and Velo Orange Grand Cru hubs. All for 126mm.

I will have to give the TZ21 Shimano a go. Seems inexpensive enough. Thanks, Dave
This bike will not be used much for loaded touring.
Other 7 speed builds may be a different story.
I have also used 8-10 speed hubs, reducing the OLN to 126mm by altering NDS spacing and redishing the whopping 2mm to the DS. However, I really like to use offset spoke center rims in those applications.
I have used 7 speed cassettes in various configurations (8 of 9; 9 of 10) with success, but I have some 7 speed brifters hanging around, just begging to be used.......

I realize you are simply repeating the same ol' predjudices about FW's .... so I won't balme you in any way.... lol.

Cassettes/FW are an Apples to Oranges comparison. Pros and Cons for Both . Choose One or both ! That's about that


I choose FW's becasue I saw what was happening to FW's at the time and bought a stock of them and cogs . Cassettes are going the same way though. Less and less choice , the fewer the speeds, the fewer the choices.

I'm all for choice .....like all of us . We want what we want when and how we want it . "Don't tell us what we cannot have(to the Bike Biz) .... I'm telling you what I want and I won't take no for an answer "
