CyclingDeal Conversion Kit Fixie Bike Single Speed Compatible with Shimano Sram Cassette Freewheel Hub Adaptor - for Mountain and Road Bike Gear Cog Spacers

I used this kit as one of the components to convert a road bike to a single speed. For background, I have a lot of experience with bicycles and am pretty good at determining the relative quality of components. I have experience with Wolftooth Components on a few bikes and consider that to be excellence with respect to these types of components (single speed or 1x setups). For this single speed setup, I used a Wolftooth chainring and a Wolftooth cog in the rear. But I needed spacers to put on my shimano freehub to tie everything together. Many of the kits were pretty expensive, but this one was inexpensive and well reviewed.It works wonderfully, exactly as advertised. The spacers (and everything in the kit) are METAL, not plastic, as some reviewers seemed to indicate. They're definitely aluminum, NOT painted plastic. There are plenty of spacers and in different sizes so it was really simple to get a perfectly straight chainline. I used their supplied 16T cog to try it out and see if 16T was right for me, but opted for my 19T Wolftooth cog. The Wolftooth is clearly a better cog, but this is no slouch. It's well made, solid, and has a pretty wide base so as to not eat into the freehub as badly. To be fair, the Wolftooth cog by itself is $60, literally four times the price of this entire conversion kit.Overall, excellent deal and excellent quality. The only thing I would like to see in the future would be a selection of various cog sizes rather than just the 16T. But I absolutely would buy this kit again, especially if I needed a 16T cog.

Super easy to install and it works great!

CyclingDeal Single Speed Conversion Kit worked perfectly for my use, should work for anyone wanting to convert a standard freehub wheel to single speed.Comes with a nice selection of spacers in various sizes allowing for adjusting the position of the sprocket to achieve the perfect chainline.Sprocket is solid, though it is not as thick as some available it is steel and so far has worn well for me.Will buy again, no complaints here.

This is a great cassette replacement for converting a Shimano freehub to single speed. Older versions of this used plastic spacers, and the fact that they wear out is what drove me to purchase this unit. The spacers on this are solid and are easy to clean. The selection of sizes mean that it is possible, by switching them out and moving them about, to get very good alignment with the chainring.The cog is not as good as the one I was going to replace. The cog on this unit is just stamped out. I suppose it is effective, and a better cog costs more than this entire kit. I used my old cog as it was beefier. I would have given this unit 4.8 stars because of the less desirable cog, but I have no problem rounding it up to a fairly accurate 5.

Works well

Okay, I honestly only bought this kit for the spacers. It was the cheapest way I could find some spacers without buying a whole singlespeed kit. The spacers are perfect and have splines machined in them to keep them from spinning. They also are definitely aluminum -- not plastic -- as other reviewers have stated.My biggest problem with this set is how poorly the parts were machined. The cog would not even fit onto my hub because it was just a millimeter or two too small -- see photo. Even if it did fit, however, I wouldn't use it on my aluminum hub body because it is very thin and would dig into the hub body, causing damage eventually. (Note the comparison photo with a beefy, more expensive, cog). The lock ring fits well onto the hub, however due to more poor machining work, my Park Tool FR-1 (a tool meant for tightening and loosening this part) would not fit into the splines on the lock ring without a bit of tapping that quite frankly scared me. I included a photo showing just the spacers on the hub for size comparison.

Spacers got everything lined up really nice.

Great for the price. Enough aluminum spacers to work with any setup I can imagine. One reviewer said the cog didn't fit their freehub, which actually is the case for my stans wheels as well. Spacers and lockring fit, but cog is just a little too small. It does fit on my other wheel, which is a bitex hub, so I guess it's just some some type of tolerance miscommunication. Didn't buy it for the cog anyway, just wanted spacers and locking. Defintely recommend if you have a shimano cassette and want to go single speed. Even matches my Wolftooth stainless cog, which is always a bonus.

Cuando lo compre casi no había este tipo de piñones para adquirir en tienda en línea, lo pagué bastante caro porque después ví que en Ali express venden productos similares y mejores a mejores precios.Sin embargo este producto cumple hasta la fecha con su función.

I was worried at first, the spacers seemed to be made of nylon but I get a weak magnetic pull when under a magnet. The bounce test makes the right sound. A little disappointed that the sprocket and spacers don’t match.Will update with an installed review.

good conversion kit and simple to use.

I used this to make my mid-nineties stumpjumper a single speed. Very easy to convert from an 8 speed. I'm not sure if they sell smaller tooth cogs but the one I got is 16t, which would be awesome except I'm running a 32t chainring so its a spinny MF when riding in traffic. Its survived a montreal winter so I cant really complain.

Nickel facile d'installation ! Rapport qualité prix imbattable. Idéal pour convertir un vieux velo de course ou remplacer un dérailleur qui ne sert pas !
