Brompton single / two speed rear wheel

Brompton two speed rear wheel

Brompton 1 or 2 speed rear wheel for all models of Brompton folding bikes complete with rim tape and fixings

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 Brompton use the single 12T sprocket set - QRSPRSTACK-BB1
For a two speed Brompton use the double 12T / 16T sprocket set - 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. The wheel nuts for the single / two speed Brompton rear wheel have the code QRW2NB.

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. Though as standard the single speed uses 12T and the two speed uses a 12T / 16T combination.

Brompton Q part code: QRW2SS
Brompton part number: 9025022 

The wheel weighs approximately 800g

The rim is a double wall straight drilled rim and has 28 Spokes

The spokes (in case you need spares) are QSPOK-151-DB-14G - Double butted with two cross lacing

Valve hole designed for 8mm Schrader / car type valve
