ConsNone for my purpose
ProsReliable, consistent, long-lasting, smooth-running
First choice for me every time from now on. Simple gear system combined with all the usual benefits of a very good, reliable drum brake. Stick to 3 speeds for durability, simplicity and efficiency. If you need more gears, walk! In my opinion and experience, there's no better solution for a commuter bicycle. Also go for Schwalbe Marathon Plus (note Plus) tyres as well, then you won't be taking the wheel off very often to fix punctures.

ConsLess hillclimbing
ProsSimpler, Stronger, Less drag
I bought this hub to replace the 5 speed version in a Pashley Roadster after two failed sun gear selector keys, too much force being put through a very small component. The 3 speed hub is much more robust as the technology is simpler. The hub is slightly narrower but will fit into the same space in the frame and the flanges are identical so the same spokes can be used. Need to ride it a bit more to let the brake bed in. With a trigger shifter, it is easier to use and the bike feels lighter on its feet.

Conswish I had bought one earlier
Proslighter weight, easier gear selection, more efficient, drum brake
I bought a Pashley Paramount about 2 years ago in Norwich. It had an SA XRD5 5 speed hub which was fine from new but had to go back twice for repair. It has failed again. There appears to have been a fault with the early batches and the gear selection. I decided to get the three speed to replace it.

The 3 speed is far easier to pedal and appears to be more efficient which makes up for the more limited gear range. Having had Shimano hub brakes in the past I really appreciate the drum brake of the SA units. I would not go back to rim brakes.

Brake lever compatible and Durability

Morning, would drop bar canti brake levers pull the correct amount of cable for the drum brake?

And could this hub be considered for long distance riding? Audax for example. Looking to use on a moulton for distance riding, thank you very much.
Drop bar cantilever brake levers (short pull) will work with this brake, as for the hub being used for long distance riding, anything is possible, the limited range of gears may be an issue, for an alternative I would look at the Nexus/Alfine 8speed hubs. SK 29/12/2022
Can I use this hub with Shimano or any other company 3-speed shifters?

Does it matter which model / company shifter to use with this hub?
Hello,

You should be able to use this with any shifter that has the same cable pull. For the best use it is is advised to use sturmey archers own shifters.

Thanks.
I Want To Know If This Hub Is The Same Of Sturmey

Archer Sab 3
Hi,

This hub is very similar to the SAB3, the only difference being this one uses an alloy hub shell where as the SAB3 still uses an older style steel hub shell.

Thanks.
