Brompton single / two speed rear wheel

The same wheel is used for the Brompton single and two speed rear wheel.

A different stack of sprockets / spacers is required based upon which configuration you need for the weel.

For a single speed use QRSPRSTACK-BB1
For a two speed use QRSPRSTACK-BB2

In addition, you will need wheel nuts - they are not supplied - as you could potentially use the old ones if you are replacing the same wheel type.

This wheel (hub) uses Shimano style splines for the sprockets - so with the correct spacers / chain length you could use different sprocket sizes if required.

Brompton part number: QRW2SS

Bearing information:

The Brompton two speed hub uses:

6900-2RS in the non-drive side
6901-2RS in the drive side

And in the freewheel body:

6900-2RS
6000-2RS
