Origin-8 Singlespeed/Fixed Gear Crank Set w/ 46T Ring. Black


Forged cranks with single 46 tooth 1/8" chainring for singlespeed/fixed-gear use.
Chainring has black finish with CNC'd highlights

165mm or 170mm arm length
Popular 130mm (road standard) bolt circle.
Crank bolts included!
670 grams.

Use 107mm Bottom bracket**

*NOTE: 1/2 x 1/8" chain will work with both 3/32" and 1/8" rear cog or freewheel.

**NOTE: There's some conflicting information, online, as to which bottom bracket width gives you the best chainline. We have found that the 103mm BB is best used with "real" track frames.

      This was purchased in conjunction with a TruVativ BB032 adapter and UN55 bottom bracket to modernize an old Columbia Sports 3 that is my current commuter. Much lighter and nicer than the old 1 piece crankset. And, the alloy has survived the salty Indianapolis winter very nicely. The option of fitting different chain rings is really cool for the old 3 speed. And, having a track style crank on the old bomb is a great conversation starter.
