    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.

    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.

      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.

            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.

                  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.

                  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.

                  Good but as I was advised can be painful to set up correctly. It ease of use and low cost make it a great way to try single speeding.

                  very good for the price. But I would not suggest it is your really hard core, but no problems with the chain tensioner.
