Does this hub use the smaller 35mm internal diameter sprockets from the 3 speed?
By Mark
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?
SJS Customer Service:
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.

By Javier Pueyo Molina

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,

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.

By Dan

SJS Customer Service:

Can you provide the 28h version?
By Rich

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.
SJS Customer Service:
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.

SJS Customer Service:
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
By Ed
20 Oct 2018
SJS Customer Service:
No sprocket comes with the hub, yes, simply select a suitable rim and wheel build/spoke option.
