Unknown Bikes
Standard Fixed Gear Wheelset
Fixed gear and single speed wheelset with a flip-flop rear hub

A black front and rear wheelset from Unknown Bikes, with 28-hole Unknown rims laced to Unknown hubs. The rear hub is fix/free: one side takes a fixed cog, the other a single-speed freewheel, so the same wheel can be ridden fixed or single speed.
The hub drivetrain is the same as on the Unknown Mushroom hubs, in a standard hub shell. The wheelset comes with a 16T cog, a lockring and a pair of WTB Freedom ThickSlick 23c tyres. The wheels are 700c, with 100 mm front and 120 mm rear hub spacing.
