Bike/Trike Freewheel Adapter For 5/8-inch Axle - HH0528, Black

Building a trike or custom bike?

This is a freewheel adapter.

It lets you mount a freewheel onto a 5/8-inch axle.

It's black, it's new, and it's the HH0528 model.

Pretty straightforward part if you're doing a custom build or conversion.

Unbranded, but it's the specific piece you need to get that rear wheel spinning and coasting properly.
