I have a Progresscycles Turbine rear hub – (this one), and I’m struggling to find information on what size of cartridge bearings it takes.

Does anyone out there know? Failing that,how do you measure/work this out? I assume the width/diameter is relevant…?

Many thanks.

A quick look at their website/catalogue shows they are a standard sealed bearing but not what size. They should have an i.d. on them somewhere,probably embossed on the seal,such as 6302RS.

Failing that, you’ll need the external diameter, internal diameter & thickness measurements.
