Incompatible Parts
I was disappointed that a single speed conversion kit does not work with a standard 1/8" single speed chain. Not only does it not work with the wider single speed chain, the 16T cog that it comes with *requires* a single speed chain. Why on earth the idler pulley groove isn't wide enough for either a 3/32" chain or a 1/8" single speed chain is beyond me. Seems like a pretty obvious thing to do. I ended up using it, but had to use the narrower 3/32" chain and narrow cassette gear and front chainring. I couldn't use the 16T cog that it came with.

PROS: Inexpensive

CONS: Parts Did Not Work Togeth

Poor product description
May end up working fine, but no mention that this isn't designed for 1/8 chains. Only after having the issue and doing some searching did I find a bunch of other people that made the mistake. Guess I'll be buying a 3/32 chain.

Directions could be a little clearer or at least bigger.

My favorite SS chain tensioner
Great value. The tensioner one is worth the price of the whole kit. The only drawback of this conversion kit is the lack of an option for different sized rear cogs. That's not a huge deal though, steel cogs are $5 at your local bike shop pretty much anywhere.

PROS: Lightweight, Attractive Design, Easy To Install

Drm delivers
I only bought chain guilde but it works great I bought a seprit cog and spacers but the gusset one on her looks about the same. If you take off the rear off alot don't buy it but if you rarely have the rear offi it's stiff as you can get. 2 bolts and on the axle mount. So if your going to put it on a dj or a daly rider that you can lock its sweet.

PROS: Fixed position, Easy to set up, One bearing, Non spring

CONS: The cog and spacing kit

The kit is all you need to convert to single speed. I used it on an 8 speed hub, but is not limited to 8 speed hubs.

PROS: Durable, Lightweight, Attractive Design, Easy To Install

BEST USES: Mountain Biking, Upgrade

Easy singlespeed conversion
Easy to install, and really cleans up the bike. Provides an easy means to convert a geared bike for singlespeed at minimal cost.

Only disappointment would be the difficulty to remove the rear tire, but that's due to the design of the tensioner. The design seems to be a good compromise between durability and ease of use.

PROS: Lightweight, Attractive Design, Easy To Install, Durable

CONS: Rear Tire Removal, Removing Rear Tire

BEST USES: Road Biking, Mountain Biking, Casual Riding

Does the job
Holds tension on the chain as designed and the cog spacers are working good. If your trying to build a budget single speed this perfect. My only complaint is that the bearings don't stay seated in the wheel.
