Can I use this with SLS40-T 4 Speed Thumb Shifter?

Do you sell the 32h version?
12 Jul 2020
No, Only 36 hole versions.

Can you provide the 28h version?
02 Jul 2019
I want to replace the fairly awful SA AW 3sp hub on my Brompton. Brompton wheels have 28 spokes, so I was wondering if you can get hold of the 28h version of the X-RF4. Thanks.
Hi, sorry the 28 hole version is not currently available from the UK importer. Unfortunatley there is no indication of future availablity either. Thanks 05/07/2019
It says in bold letters comes with shifter and sprocket.

Generally, we supply Sturmey hubs without sprockets and Shifters (at a suitably reduced price) because (oddly) Sturmey change which sprocket and shifter they include with a hub to suit I think what they have. In THIS case at THIS MOMENT our reply to you was WRONG, sorry, the CURRENT stock IS supplied with a twist shifter and an 18t sprocket HOWEVER this may change over time. RT 24/10/18
What size and type of sprocket comes with this hub? Also can I buy it built on to a 24
20 Oct 2018
No sprocket comes with the hub, yes, simply select a suitable rim and wheel build/spoke option.

Thanks - 22/10/18
