freewheel from the brand sachs mailiard made in france. I campared it with all offers from Park tool, the most probable tool is FR 1 compatible with sachs, because this is the only one that menthions Sachs.
Cassette and Freewheel Removal and Installation | Park Tool
If I buy this tool and later I can also use it for all shimano freewheel , right? and it is said all freewheel threads are the same from all brands , thus their freewheel of all speeds are interchangable, such as my present one is sachs 6 speeds freewheel, can I just replace it with 7 speed shimano freewheel, or I can only use 6 speed from shimano please?

The FR1 should fit the SACHS freewheel and allow it's removal from the wheel. Then you get to find out the hub's threading. SACHS did make some French threaded stuff so one really doesn't know yet the actual thread standard. But it is likely to be Eng/ISO.


What we don't also know is how much axle extends from the hub's RH side. How far between the freewheel threading seat and the axle's lock nut outer face? Whether there's enough unused clearance to allow an additional cog. 7 speed cogs have a narrower c-c dimension then 6 has but the overall width is still usually slightly more then the 6. Andy.

Not a Sachs/Maillard... Shimano and Suntour along with the required tools. I cannot see from your picture where the appropriate tool would mate with the freewheel.

Tentatively Yes. All freewheels have the same thread which attaches to the hub so in that respect they are interchangeable. Swapping out a 6 for a 7 may cause other problems. Without trying to find out elsewhere you may need to spread the stays to accept the 7. I am guessing but someone else will know... the build height might be the same.

Of course moving from a 6 to a 7 will mess with your dérailleur/shifter if you have indexed shifting.

Mr Stewart says it better than me.

French Malliard was going years before they became part of the Fichtel-Sachs group of companies.

they no longer survive, SRAM bought out Sachs and shipped everything out of Europe

an Malliard could not stay in business on its own..


Bene Sugg : take the wheel to a Pro Bike Shop They will take off that freewheel with their tool
then get the removal tool for the new freewheel you get to replace it.

Why buy a removal tool to use Once?

Tool Fetish. They also come in handy when you need to use them again. N+1 bikes fades in comparison to Tool Fetish. After all what's the point of having N+1 bikes if you do not have the tools to maintain them?

What brand is the hub? This might give you insight into what the freewheel threading is.

For what a lbs might charge, the tool might be afforded more than once after all said and done.

do not know if it fits with 7 speed shimano

Well, then I'll tell you: any 126OLD ospacing will accept either a 6 or 7 speed freewheel, as it was the standard used at the time. Yes, you may need to add a thin shim at the freewheel end of the axle to keep the smallest 7 speed cog from hitting the inside of an otherwise 6 speed dropout, but that's pretty minor.

The larger issue is that the crappy initial pic makes it impossible to determine what freewheel removal tool is required to take off the subject freewheel. So the advice to go to a competent LBS to remove the existant freewheel is well made. Do that.

Then install a good vintage or current Shimano freewheel and use the tool mentioned in your original post.

So-called "destructive" removal isn't always destructive. If you disassemble the freewheel and hold the center in a bench vise with aluminum or copper jaw inserts, using the rim as a lever, there's a good chance the center will come out without damage.

squirtdad

just to confrim you are talking about removing freewheel from wheel, correct? not opening up the freewheel for maintenance?

maddog34

it will work, and will fit a slew of modern freewheels too.

your freewheel is the newer version Sachs M alliard... the OLDER Sachs freewheels had a two prong tool that absolutely loves to jump out of it's notches when you tried to get the horridly stuck freewheels loose... or break... or screw up the freewheel bodies....... good riddance to pronged freewheel removers.... sadly, BMX crap still uses them...

With few exceptions, freewheel hub threading , 1.370x24tpi , has become international standard.

hermanchauw

because it is cheaper to buy a tool (from China) than to (spend time/money transporting your bike to the bike shop and) pay a mechanic to do the job for you.

fietsbob

walking is even cheaper , if all you think about is being cheap.

I agree with some others...

Got some local bike shops? Take the wheel off, show it too them and they may offer to remove the freewheel for free. At the most, less than 10 bucks. Get them to show you what they use, then you'll know. But you do need to be careful to determine what the correct threading is before installing a new one. The difference is so little you may well damage the hub before you find out the threading is incorrect.

Of course what I come up with googling for a removal tool for Maillard look like this..... https://www.ebay.com/p/Maillard-Free...t-3/1131366846

quite a bit different from Shimano. And no, the Shimano freewheel removal tool will not work on Shimano cassettes..... At least my Shimano cassette tool doesn't seem to work on my Shimano freewheel. Of course Maillards may have changed over the years so if they made freewheels in the last 20 years they may be Shimano standard..... maybe.

Possible that your LBS may not have the right removal tool if they don't service bikes with that freewheel a lot. But doesn't hurt to ask. I was visiting a LBS in another town for the first time the other day and struck up a conversation with the owner. Before leaving I bought a couple bottle cages and then ask if he had an old style Garmin Speed/Cadence sensor. He went to the back and pulled one from the shelf that looked virtually unused and GAVE it to me for FREE. On Ebay I would have paid 40 to 60 bucks for it.

So not all LBS's deserve the bad reputation many people give.

find 2 passengers and asked for help, they found a long tube looking like from the heat supply loop, and then click, it moved. the freewheel tool is correct. shimano and sachs have the same splines inside.

dabac

You DIDN'T open the f/w, you REMOVED the f/w from the hub.

There IS a difference.

Your inability/unwillingness to use the right words will pretty soon influence the quality of help you're likely to receive.
Either through frustration, or simply b/c not understanding what you're asking about.

box opener

you are totally right.
