I see that you have to thread this through the unit. Will this work on a one-speed with a chain that has no slack?

I have a one speed as well but I created slack by taking off the back wheel.

Frank, It's the right pitch, but it's too narrow. You need a 5-6 speed chain, which is slightly wider than the 7-8 speed chain. 7-8 sp. chain may go on, but it will probably bind on the sprockets.

According to the package it will work on 7 and 8 speed derailleur chains. It does not differentiate between companies. I carry it but haven't had to use it yet

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 :) ).

I use mine on a bobbin winder that is only one speed--fast. I needed to slow it down. This pedal makes it a variable speed.

No. Chain will be too wide for the spacing in between the cogs on the cassette. You will need a 9 speed specific chain

Probably yes. since it is for 7 speeds, it will probably do fine for 6 speeds, since it is a fairly standard derailleur, though you may have to make adjustments in the cable tension and/or stops. Also, note that this attaches to the axle bolt. So make sure that's how your bike holds its current derailleur. Look at http://sheldonbrown.com/speeds.html

No. This product is made for cassette hubs only. That is, a hub with the freehub mechanism attached by spline, sold as one unit. The cassette slides onto this type of hub and connects with a lockring. What I believe you are looking for is a multispeed freewheel, which is an older style unit integrating cogs and freewheel ratcheting mechanism. This type of unit screws tightly onto the threads of the matching freewheel hub and stays put until it is pulled with a splined or toothed freewheel remover. The two systems are not interchangeable. Search instead for a "7 speed freewheel". Hope this helps.

This chain matches an 8 speed freehub or freewheel. That is, if you count the sprockets (cogs) on your rear wheel hub and you have 8 then this chain will probably work. Count the number of links in your old chain and use the same number for the new chain. If the new chain has more links you should remove some of them. Removal takes a chain tool.

I agree with Ken S response. I would add you may not have to remove the links but just connect at the link that provide the tighten the chains as desired.

It does works on SRAM chains. Just make sure you have the right chain. 7,8,9 or 10 link for the same chain.
1402433
Yes it will work! The stock chain is 520 pitch by 110 links! You will have to cut some links off of it!
268637
It should, but you may need to remove the biggest chainring, since this was designed with a single chainring setup in mind.

the ratchet system will only allow for three speed automatics. unless the unit is designed for a 4 speed don't assume it will work. mine came with all hardware and parts to complete the job.
571231
Yes, assuming it's a 10-speed cassette. I have used this chain with a 10-speed 11-32 cassette and 50/34 chainset.

Depends on your chainline. You want your chainring as close in line with your sprocket as possible. So you'll need to measure what spindle length you need(in mm) in order for the chain to run smooth. I have an older steel frame and I used like a 107... something like that.

My sense is yes. The bike I put this on is a 9 speed but I have a 9 speed LX crank with an 8 speed cassette on another bike.I am using a Shram 951 chain on both. Hope this helps. Chris
