I have a 1997-ish Mongoose MGX 21 speed Dept store MT bike with the screw freewheel hub. will this work on it? Could use the Super Low where I ride.

Depends on the existing deraileur, things like long cage and shifter components being shimano compatible have to be there. Chain length may need to be addressed.

The Tourney freewheel has a nominal 34mm threaded female connection to screw onto the hub of your back wheel. Its measurements from gear 1 to gear 7 top dead center is a nominal 32 mm. You should compare this to the freewheel that you are replacing. Whether you can get to the super low will very much depend on your rear derailleur.

Yeah , but will need to adjust chain length . Recommend new chain/master link ( wallyworld sells a good cheap set)Adjust length so that there's two extra links ( counting the master;)) when chain's around the biggest sprockets .Good luck

It should work fine. I put mine on a Venzo Scud 29er MTB that I built up. The Venzo has a 31.8 clamp diameter.

Should work just fine. I use it all the time for older lugged bikes I rebuild. The weight don't seem to be an issue but I'm not sure if it would be a problem if you have a large top tube. Example if it's a square tube. Honestly I think it would work fine if you don't want to spend the money for a park tool stand.

Well, what can I say to help, make a few phone calls to bicycle shops in your area. But as long as it relates to a seven shifting options for you, I can't see any problems. My old 1994 ROSS Mt. Olympus 21 speed mountain bike, it work for me. I replaced both shifters, the original ones just tired out, yet my derailleurs are still going strong today. My opinion, they work better how the shifter buttons relate on the handle bars. Once I got them lined up & running they work great. How was that?

Yes it will. The pull ratio is not 1:1-- this has the same ratio as all older Shimano ders. The only problem you might have is if you run a slightly wider chain through it. I don't think it will jam up or anything crazy like that, but you might get a little rubbing on the cage as the chain deflection increases (i.e. while you're cross chained). Just run a 9-speed chain and you'll be completely okay. Again, not that the 8-speed chain is going to lead to a catastrophe. Shimano did change their pull ratio when they moved their mountain drive trains to 10-speed. This is a little annoying, but at least there are more modern 9-speed options available (10-speed road ders will still work on lower-speed mountain drivetrains, though. I'm running a 10-speed 105 der on a 7 speed drive train with an indexed shifter :) ).

This is a screw on freewheel requiring threads on the rear hub popular on older bikes 1990's and older. I believe newer bikes use cassettes and are not interchangeable. Perhaps some less expensive bikes may still use freewheels. You can take your rear wheel to your local bike store and they can tell you what you have. You will need some kind of removal tool you can buy from them anyway.

you can probably use the same derailer and just adjust it for the different size, as far as the chain sizes and stuff, I know almost enough to be dangerous when it comes to bike building and repairing, The way I figure it though, your current chain should be right about the correct size for the changes you are looking at making. As the other person responded make sure this will work for your hub, if you have a freehub this will work (you also need the tool to take the keeper off of the hub) if you do not, you would need a freewheel cassette. The difference is the free hub has the ratcheting mechanism in the hub and the freewheel has it in the casssette and the cassette is removed from the hub. I didn't realize there was a difference before I bought this and ended up getting a new rear wheel to go with my brand new cassette.

Any threaded rear bmx style or single speed mtn hub , such as- profile design , dmr, white industries, chris king... etc. Also some "flip flop" style track hubs . check city grounds . com or dans bmx .com . I used the DMR revolver hubs myself . ... good luck

Yes, the MF-TZ20 should thread right onto this wheel. I used a 7 speed DNP on mine but the threads are the same so you should have no issue.

The hub becomes a freewheel, not a fixed gear. This kit worked great. I replaced a 10 cog txt hub with it. Shims make it easy to adjust in minutes. I am very pleased. I used in combination with soul craft tensioner which also worked great. The only way to go.

It certainly looks as though it would. Both are 7-speed freewheels of the same overall range. There might be some minor differences in the between cogs, but nothing that should prevent it from working well.

Dear Juice: There are two systems. One is the older-style freewheel where the cog unit goes screwed on the hub of the rear wheel. This Shimano Tourney is one of those screw-on cogs. The newer system is where the cog unit -called a cassette- goes pushed and then locked on a splined extension of the hub. Both systems are not compatible. My advise is get a bike mechanic or a friend who knows the difference between the two systems have a look at your bike and tell you which system it has before you spend the money :-) Hope this helps, Andy :-)

Not without some machining to the frame. This hub, like all bike hubs, uses a 7 inch axle. The Meridian as delivered from Schwinn uses an 8 inch axle. To use any replacement hub requires moving the hub backwards about 2 inches by extending the slot in the frame it sits in and redrilling the associated bolt holes for holding the rear frame to the front frame. I recommend having your bike shop do this due to the level of precision required. The job isn't cheap but it is more than worth it. I suspect other adult trikes are similar.

It should, I used it for MTB single speed conversion. At the time and still might be, it was marked as free return, for the price it's great too. Good luck.

As long as your rear wheel is roughly the size of a ten speed wheel, or mountain bike wheel, you are good. The unit comes with an axle that you can use to ensure proper fitment on the unit. You should be fine with.

A few questions. Does your bike have a freewheel hub or a cassette hub? On a freewheel hub, you should see a ring of internal splines on the inside of the bearing ring. What brand is your shifter and derailleur? If the shifter is Shimano, this should have the correct gear spacing. This is very critical if you have indexed shifting. How many teeth on the big gear on your present freewheel? If 28, good, otherwise, you may need to lengthen or shorten the chain. Note that when changing the freewheel, it is a good time to replace the chain. Do you have and know how to use a freewheel removal tool? It usually takes a fair amount of force to remove the old freewheel and you must use the correct freewheel tool. A mounted bench vise, or a long box end wrench is also required. From the answers to the questions above, you should be able to determine if this will work for your bike.

Wheel hubs, where you attach these, are generally made in two sizes: for 7 cogs or less, or for 8 and up. It probably won't fit. See Sheldon Brown's site for more than you ever wanted to know about bikes.
