Is it suitable for gravel/ mild off road?

By Adam Dolling

12 Sep 2020

SJS Customer Service:

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?

Hi

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?

SJS Customer Service:

The chainline is dependant on the sprocket fitted,the variables can be seen here - http://www.sturmey-archer.com/files/catalog/files/308/SPECIFICATIONS%20-%20IGH%20S30.pdf

Thanks

Confused when comparing different versions of SA 3-speed IGH...

By Mike

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?

Thanks.

SJS Customer Service:

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

Thanks

SA S-RK3 3Spd Disc Hub listed - rotary gear selector?

By Che

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.
Thanks

SJS Customer Service:

Hello,

This does not have the rotary gear selector.

Thanks.

Raleigh Chopper Conversion

By Peter Leid

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?

SJS Customer Service:

Hi,

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

Thanks.

Will This Hub Fit A 114Mm Rear Spacing?

By Bob

01 Sep 2016

I have a 1951 Raleigh Lenton Sports frame.

SJS Customer Service:

Hi,

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

Thanks.

Can You Supply This Hub In 32 Hole Please?

By Pete

13 Jul 2016

SJS Customer Service:

Hi,

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

Thanks.

Hub Gear Conversion

By Pete Stevens

04 Nov 2015

Hi,

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,
Pete

SJS Customer Service:

Hi,

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.

Thanks.
