Question: Will this work on a Sram hub?
Document: works great, has everything you need to convert a shimano style rear hub to have a single cog instead of a cassette
I have about one hundred miles on this adaptor. Nothing but single speed smiles so far. It's on a dept. store  project bike with a slightly upgraded crankset and new rear wheel. I bought a 3 ring crankset just in case the SS idea didn't work. The chain is on the center ring and this fixie adaptor made it easy to line up the chain. The gear ratio is perfect on the flat streets I ride on.
Works well, but it would be nice if it came with a few options for gearing
Spacers are silver colored plastic. Cog is very thin, I'm worried it would tear up my freehub. I ended up going with a different single speed specific cog that has a wider base. Plastic spacers are probably worth 25 cents. I'm going to find some alloy spacers, so I ended up paying $15 for a lockring.
So easy to install, fun to ride and priced so low I'm thinking of putting one on my other bike.
It works! This product doesn't come with a manual, so you'll have to figure it out on your own. In case you didn't notice, you'll need a shimano freehub. They seem to be available as screw-on hubs and full hubs, the latter of which you'll have to deal with attaching and truing spokes with. It's a simple product and does what it's supposed to do.
I've been using this for several months now. Very easy to install and adjust to get a good chain line. It's well made, sturdy, light, and has a nice machined finish.
I was a little skeptical considering this was the least expensive conversion kit I could find, but I was really impressed with everything when it arrived. The fit and finish is not bad at all and the kit includes everything you need to switch over to single speed (no tools obviously). I would definitely order another kit for any future single speed build. Oh yeah, the shipping was also very fast! !
I recently upgraded my wheelset on my SS to stans crest, but this was from a geared bike. i purchase this adaptor, it was low cost and easy to install. it  works great.
I purchased this single speed adaptor for my mountain bike conversion. For the price, it is great. There is enough spacers to get your chain to line up straight with the cog on your crank.
Answer: no
