ProsPerfect for Brompton
15t sprocket for a 3 speed sturmey like the current BSR hub.
15t does fit Brompton!
Anything bigger not without frame mods.

ConsNone found so far.
ProsDirect replacement part to keep the wheels turning
Now that Brompton no longer support earlier models with SRAM gears, keeping these bikes going is a concern. This is especially the case with items that wear such as transmission parts. Great to find this part available.

I have a 6 speed with Sachs hub, 15 & 13 t can I use this with spacers to replace cog?s..... the complete kit seems to have been discontinued everywhere?
Hi! This should work, we have not tested it and do not have a Sachs hub here to try. The kits are no longer produced as hubs stopped being used about 15 years ago.

Hi there,

Unfortunately, we do not have any 3/32 sprockets with 13 or 14 teeth im afraid.

Can I use this to change my 3 speed Brompton 13T rear sprocket
12 May 2019
I want to change my 13T Brompton sprocket

yes, you can use this.

Will this fit a Brompton BWR hub in conjunction with the Brompton 9-spline 12t sprocket? Thanks

Hi there,

No it will not fit as it is a 3 spline sprocket.

You need either SJS Cycles part number : 22347 OR SJS Cycles part number : 13766

Both sprockets need to be replaced when you replace the chain at 100% worn otherwise the chain will slip on them. 6speed models use 13/16t and 2speed use 12/16t.
