Is it possible to do...
Hi all,
I'm 7,000 mi. from my tools, too dang far downhill(6 mi) from the bike shop and w/out a car. I'm also too irritated and cheap to buy ANOTHER chainwhip and impatient to wait for one thru the mail by internet purchase.
Can I remove a cassette from a freehub without a chainwhip, using only a lockring removal tool？ Ｉ ｒｅｍｅｍｂｅｒ ｒｅａｄｉｎｇ ｓｏｍｅｗｈｅｒｅ ｏｆ ａ ｈｏｍｅｂｒｅｗ ｍｅｔｈｏｄ ｏｆ ”ｉｍｉｔａｔｉｎｇ” ａ ｃｈａｉｎｗｈｉｐ ｕｓｉｎｇ ｔｈｅ ｃｈａｉｎ ｏｎ ｔｈｅ ｂｉｋｅ ｏｒ ａ ｌｅｎｇｔｈ ｏｆ ａｎｏｔｈｅｒ ｆｏｒ ｔｈｉｓ． Ｔｈｉｓ ｉｓ ｐｒｏｂａｂｌｙ ｓｏｍｅｔｈｉｎｇ ｆｒｏｍ ｂｉｋｅｌｏｒｅ ｍａｎｙ ｙｅａｒｓ ａｇｏ．

I have been up all night and my reasoning skills are shot, but you may be able to rotofix (rotafix?) it off. I know it can be done on a fixed gear, but am having trouble thinking through the implications of a freewheel. Wouldn't hurt to search for more info on it though.

Try using an old piece of chain and a visegrip. Good luck.

I've done it before. Wrap a chain around one of the cogs so that the chain is on the ground on the forward side of the free wheel (direction of forward rotation), make sure you've got a few inches of chain on the ground. Lean the assembly with chain side out against a wall or something like that, put the cassette removal tool in place, step on the part of the chain that is on the ground, and proceed to remove the cassette. I got this idea from Utahmountainbiking.com. He says:
"If you don't have a chain whip, just use a section of chain to immobilize the freewheel. I just take an old broken chain, drape it over the top of the big cog, then stand on the other end with [your] foot. Works great!"
Eventhough I normally use a chain whip, this fix works great in a bind.

Here is the rotafix method.

It should work since you can reverse the process to secure the cog/freewheel from either direction of rotation. Make sure you protect the bottom bracket shell from the chain with a rag.

When I needed to change cogs I just used an old chain. It never occurred to me that it may not be possible, so I just approached it logically and it worked just fine.
I put the splined remover in a vice, wrapped the chain around the cogs, put the wheel into the remover and grabbed the chain and spokes together in a rag and turned.
