It would be a worthy alternative to the Dual Drive. SK 17/08/23

Question 2

Can I use on tandem

By Anthony

16 Aug 2022

Would this hub be strong enough to use with a tandem?

SJS Customer Service: · Answer

No! The manufacturer seems happy to offer their hubs for e-bike use but we've seen failures already. We think no, you could use it gently but no warranty from us! RT 16/08/2022

Spacer for 7 speed cassette for Sturmey Archer RF3 3Spd Cassette Hub - 36 Hole

By Philip

20 Aug 2020

Your answer on 11 November 2016 said that I need a spacer to use this for a 7 speed cassette, part number 3888. However, a search for this part on the website does not get any useful results. Do you still sell a spacer for this purpose?

SJS Cycles part number : 18561

Thanks - 21/08/20

28h workaround

By fausto99

13 Apr 2020

Would or could this hub's innards fit in an old SA 28 hole shell?

SJS Customer Service: · Answer

no, sorry, using different length spokes it's possible to build a 36 hole hub into a 28 hole rim. RT 14/04/2020

Question 7

Question 8

Chain ring to sprocket ratio

By Christopher

26 Jun 2019

Hi, Rohloff and Shimano provide ratios with regard to chain ring size to sprocket size as to not overcharge the hub (e.g. for a Rohloff the chain ring should at least have 1.9 times the number of teeth as the sprocket). What is the ratio for this hub?
Thanks for your help, Christopher

SJS Customer Service: · Answer

Hi there,

Unfortunately, we have not been provided with kind of information so we would have no idea I'm afraid.

Thanks.

Question 9

gear range

By S WInfield

02 Mar 2019

I was very intrigued by this product. Kids' bikes in the 1970s only had this!

I have two questions. What would be the overall gear range when combined with a 8 gear cassette and second question could you still keep a 3 gear cassette on the pedals? Is it possible to fix the additional cable on a standard v brake 26 inch wheel bicycle with th corresponding Sturmey Archer lever thing to change gear?

I understant the hub itself has a 177% gear range.

SJS Customer Service: · Answer

Hi, the total range will depend on the sprockets chosen, yes you can use a triple front chainwheel too and yes there will be outer cable from the lever to the hub which can be affixed with zip ties

Question 10

Minimum OLD for this hub

By Graham Bowers

16 Jul 2017

I see the specified OLD for this hub is 135 mm, but see that there are double locknouts on the non-drive side. Can you please tell me the minimum OLD that may be achieved following removal of any locknuts and washers that are not absolutely necessary?

SJS Customer Service: · Answer

Hello,

The minimum you could get it down to is 125mm.

Thanks.

Question 11

Does It Skip?

By Neil

25 Feb 2017

Hi I currently have this hub made by neos triniti and it skips in 3rd gear. I can't seem to solve it and am considering getting a new wheel altogether built up around this hub. I just want to make sure it's reliable! Have you heard of many problems with this hub?

SJS Customer Service: · Answer

Hi,

Sturmey Archer 3spds are some of the most reliable hubs ever made, this version with the cassette freewheel has more going on so will have a higher risk of developing an issue but we never really had an issues in all of the ones we've sold.

Thanks.

Question 12

Shifter Recomendation

By Mick Fairhurst

11 Jan 2017

You haven't answered my question above

Which shifter do you recommend for this hub?
Which ones from your range do you recommend?

I have no experience of MTBs, so I'm in the dark about this.

I want to use this hub and use dropped handlebars. If a bar end shifter isn't available, what are my options?

Thanks and regards,
Mick.

SJS Customer Service: · Answer

Hi,

The reason I have not recommended an individual shifter is that we sell a larger number of compatible options that are all of high enough quality that can be used. Unfortunately as you want to run drop bars it does mean that there aren't any compatible options. The shifters suitable for use with this hub are all either twistshifters or trigger shifters, neither of which can be used with drop bars i'm afraid.

Thanks.

Question 13

Shifter Recommendation

By Mick Fairhurst

09 Jan 2017

Which shifter do you recommend for this hub?
I would like a bar end shifter. Do they exist?
Do you do them?

Thanks.

SJS Customer Service: · Answer

Hi,

This hub is designed to be used with a standard MTB type 3spd left hand shifter usually used for a front derailleur. You would not be able to use a bar end shifter as these are almost always friction rather than indexed so do not have 3 set gear positions which you require for this hub. You will need to use a gear shifter with MTB cable pull and 3 set positions; these will normally include trigger shifters and twist shifters.

Thanks.

Question 14

Do You Do The Cs-Rf3 In 28H?

By Mick Fairhurst

08 Jan 2017

I would like this hub in 28h to go into my existing wheelset.

Can you get hold of one in 28h?

Thanks.

SJS Customer Service: · Answer

Hi,

Unfortunately we are not able to get hold of one in 28h as Sturmey Archer Europe only bring the 36h version into Europe.

Thanks.

Question 15

Can I Get Sturmey Archer Cs-Rf3 Black 28 Holes

By Borja

04 Jan 2017

SJS Customer Service: · Answer

Hi,

Unfortunately the black version of the CS-RF3 is not available from Sturmey Archer Europe so Sturmey Archer's UK distributor can't order it and as they can't get it we can't get it from them I'm afraid.

Thanks.

Question 16

Would A Seven Speed Cassette Be Compatible?

By paul stevens

11 Nov 2016

SJS Customer Service: · Answer

Hi,

You would need to fit a spacer to allow this hub to be compatible with a 7spd cassette. We stock these and are SJSC part number 3888.

Thanks.

Question 17

By scott

11 May 2016

Thanks.

Question 18

By scott

08 May 2016

SJS Customer Service: · Answer

Hi,

The Sturmey Archer 3spd bar end shifter is indeed compatible with this hub.

Thanks.

Question 19

It Is Listed As 8&9 Speed, Would A 10 Speed Cassette Work?

By roy

28 Mar 2016

SJS Customer Service: · Answer

Hi,

8, 9 and 10spd cassettes all fit to the same size freehub body so you could easily fit a 10spd cassette to this hub if you wanted to.

Thanks.

Question 20

Is It Possible To Have This Hub Threaded For A Karasawa Drag Brake

By Bart

22 Mar 2016

Can this hub (left side of course) be threaded by SJS Cycles to accomodate your Karasawa screw on drag brake?

Regards,

Bart

SJS Customer Service: · Answer

Hi,

We are not able to thread any hubs in this way I'm afraid and with this hub there would not be enough space to get enough threads either.

Thanks.

Question 21

Hello Can You Get Hold Of The Black Version Of This Hub?

By Karl

06 Nov 2014

SJS Customer Service: · Answer

Hi,

We're not able to get hold of this exact model in black, but we do have the disc brake version (RK3) available in black in either 32 or 36 hole options. You don't require a disc brake to use it though, you can build it up into a normal rim and use it with rim brakes if you wish.

Thanks.

Question 22

Gear Shifter For Sturmey Archer Rf3 3Spd Cassette Hub

By Tim Devereux

03 Aug 2014

Hi, I have aTrice Classic recumbent trike, which originally had a Sram Dual Drive 9x3 hub + derailleur gears fitted, but the hub gears broke irreparabl some time ago, so have been running it with ordinary derailleur gears & a cassette hub.
I'm very interested in the Sturmey Archer Rf3 3Spd Cassette Hub 36H, but would also need a gear shifter for the hub gears. A twistgrip shifter would probably not fit, but a lever type shifter would be suitable. What shifters do you have, & how much?

Many thanks!

SJS Customer Service: · Answer

Hi,

This hub despite being a hub gear actually uses a standard MTB style 3spd shifter, so any normal shifter used for the front derailleur on a conventional geared system will be compatible. So this means any shifter by Shimano or Sram will work fine.

Thanks.
