Rated 4.4 out of 5 stars.
Overhauling a single-speed bike, beach cruiser, or fixie?
You'll need a new freewheel.
This pack includes two 18-tooth freewheels, which is a pretty common size.
They're compatible with standard 1/2\ x 1/8\ bicycle chains.
The inner diameter is 34.1mm (about 1.34\), designed to thread onto a standard rear bicycle hub.
Made from tough steel, they're built to handle pedaling force and should spin smoothly.
Having two is great – one for your bike and a spare, or for building two bikes.
Remember, you'll need a special freewheel removal tool to install and remove it.
An essential part for any single-speed bike project or repair.
