Fixed-gear/track hubs are also quite suitable for singlespeed freewheeling bicycles. Any standard track hub will accept a one-speed freewheel with no modifications required. Track hubs are listed on our separate Fixed Gear Hub Page.Track hubs are a good choice for converting a road frame to singlespeed, but they are not so good for mountain bike conversions. Track hubs usually require axle replacement to fit the standard 135 mm spacing of MTB frames. In addition, the closer-in chainline of track hubs (typically 41-42 mm) won't work with most MTB frames. The wide chainstay spacing forces the chainring too far out, unless you use a very tiny chainring. Most of the singlespeed hubs shown on this page have a 52 mm chainline, which lines up with the outer position on a typical MTB triple crankset.
A single-speed (BMX) freewheel is a modular unit, consisting of a single sprocket and its associated freewheel (coasting) mechanism. These have standard 1.37" x 24 tpi threads, and fit on any hub that takes a thread-on freewheel. This includes BMX hubs, track hubs, and multi-speed freewheel hubs.Black-Ops one-speed freewheels (Click cart button for price)
They come in 16, 17 & 18 tooth sizes, and will work with either 3/32" or 1/8" chains.
