Does this hub use the smaller 35mm internal diameter sprockets from the 3 speed?
03 Jul 2022
Also I have a bike fitted with the RX-RF5 5 speed which has an annoying ticking when in use, I have checked everything such as chainline and adjustment and have seen comments on a couple of fora saying they all do that and you have to live with it, have you heard of any such issues with this hub?
This does take 35mm ID 3 notch sprockets. We have not yet fitted one in the shop so I cannot pass comment on these other issues.

Sturmey Archer X-RF4 4 Speed Rotary Freewheel Rear Hub - 36 Hole
28 Dec 2021
Please I would like to know if this rear hub set can be supplied with shifter SLS40 instead of current TSS42.
Please I would like to know if this rear hub will dimensionally fit on following 28" wheels.

Thank you in advance,
Best regards,
Javier Pueyo
Hi, sadly we cannot swap out the shifter, you would need to order in addition to the one included if you want a different one.

As we don't sell these wheels we cannot confirm if this would work, however as long as the spoke hole count is the same then technically it should work, when fitted with new spokes of the correct length.

What spokes (guage) are suitable for use with 700c
18 Aug 2021
SA recommends use of 13 / 14 G spokes with this hub.

JK 18.08.21
Can I use this with SLS40-T 4 Speed Thumb Shifter?
12 May 2021
Thank you for your enquiry, yes this will work fine

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.
24 Oct 2018
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
What is the Over Locknut Dimension for this hub ?
03 Jul 2018

Kind Regards
