My steel track frame OLN is 116mm, with enough flex to go up to 120mm.

By James Morgan

26 Nov 2019

Is this 8 speed Sturmey Archer with drum brake available in 120 OLN? Even if to special order? I need the hub brake as the track frame has no provision for a V brake. I need the gears because I am an old git, too old for single speeds as I live on the Mid Wales coast.
Thank you

SJS Customer Service:

Hi there,

Unfortunately, this hub is not available with a 120mm OLN I'm afraid.

Thanks.

Can I replace an XL-RD3 with this hub?

By Ben Thorp

I have a bike with an existing XL-RD3, but would like to increase the number of gears. Obviously I would need to replace the shifter, but otherwise would this hub work?

SJS Customer Service:

As long as the dropouts are the same for the OLN distance then yes you could fit this to your bike.

Hi,

This is an 8spd internal gear hub, it does still have a freewheel mechanism built in though.

Thanks.

Hi,

Unfortunately not, the largest sprocket available for the Sturmey Archer 8spd hubs is 25T.

Thanks.
