Brompton 3 speed BSR rear wheel with Sturmey Archer hub

This wheel is only available in silver
(the BWR - wide ratio, front wheel and single / two speed rear wheels are also available in black)

The Brompton sprocket stack is a separate item (not included) and can be found on the "related stuff" tab - this is because there is a choice of a 13T or 14T sprocket set as standard from Brompton. You may also wish to reuse your existing sprockets

We made this short video to show how the sprocket stack (chain guard / sprocket and circlip) are installed on the Brompton 3 speed BSR (Brompton Standard Ratio) rear wheel

And this video on how to remove the sprocket set from this wheel

And this video shows how to set up the Brompton hub gears

The BSR - Brompton Standard Ratio rear wheel was introduced in 2009
