Is it suitable for gravel/ mild off road?
12 Sep 2020
Hello, for use in these conditions an increase in maintenance and cleaning would be required due to the more demanding environment the hub is being used in.
What's the chainline of this hub, please?
21 Jul 2018

This looks like just the thing for a 3 speed conversion I want to do.

What's the chainline, please? And do you sell a tensioner that would be compatible?
The chainline is dependant on the sprocket fitted,the variables can be seen here -

Confused when comparing different versions of SA 3-speed IGH...
01 Jul 2018
I want/need a Sturmey Archer 3-speed IGH that fits 135mm frame width. With disc brake. That I can backpedaling without engaging any (aka coaster?) brakes or anything else that won´t allowing the pedals going backwards.

As well as being able to rest from pedaling but still moving forward (aka freewheel?).

Does this hub allow the abovementioned requirements?

This hub will be suitable for your needs with a speed hub gear, disc brake, no pedal back coaster and 135mm width.

SA S-RK3 3Spd Disc Hub listed - rotary gear selector?
25 Sep 2017
The image appears to be the RS-RK3, which I've not been able to find anywhere. If it is the RS-RK3 with the rotary gear selector I'll buy one.

This does not have the rotary gear selector.

Raleigh Chopper Conversion

I'D Like To Up-Grade My 2004 (Alloy Frame) Raleigh Chopper To A 3 Speed And Disc Brake Rather Than V Brakes. Is This Possible With This Unit?

As long as your frame has a rear dropout spacing of 135mm then this hub can be fitted to your bike.

Will This Hub Fit A 114Mm Rear Spacing?
01 Sep 2016
I have a 1951 Raleigh Lenton Sports frame.

As this is the disc brake version it has an OLN measurement of 135mm so won't fit your frame I'm afraid.

Can You Supply This Hub In 32 Hole Please?
13 Jul 2016

Unfortunately Sturmey Archer Europe only bring in the 36H version so this is all we're able to offer I'm afraid.

Hub Gear Conversion
04 Nov 2015

I'm planning on converting one of my bikes from a derailleur to a hub gear and have a question with regards to the cable routing. Do you sell the cable stop that's usually found on the chain or seat stays of the frame? The hub gear I'm planning on buying is the Sturmey Archer SRK3 .

Thanks for your help,

We do sell the chainstay cable clips/stops as individual items, but if you're going to be purchasing one of these hubs then you hopefully should not need to purchase one because you get one included with the hub.
