I currently have a two speed Brompton and want to convert it to a single speed. If I order part numberv45399T12 I
Assume I will also need part number 13765. I will need spacers to fill in the gap where the other spocket shouId be? I hope this makes sense.
Many thanks
Hi, yes you can use the spacers from 13765 with the Ti-Parts sprocket for your conversion. Thanks
Would 18T / 19T fit Brompton 2 speed?
03 Sep 2018

Please advise if it is possible to fit 18T or 19T sprockets on my Brompton 2 speed? Current chain ring is 54T / 12T
Yes these should fit, the 19t can hit the frame if you have a titanium rear triangle.

Hello, are these sprockets suitable with Rohloff??

Hi there,

No, these are not suitable for Rohloff use.

Brompton 2 speed to 3 speed?
20 Mar 2018
Hi, Are these the narrow sprockets that would allow you to fit 3 in place of the usual standard 2? (I have an indexed 3 speed shifter already, a narrow 11 speed chain, and I'm assuming the old chain pusher would work..?)

Thank you.
Hi there,

Yes these are the replacements for the sprockets in the kit - SJS Cycles part number : 36535T369

Can I use as 2 speeds sprocket for Brompton
26 Jan 2018
I have a Brompton S2-X and would like to replace the original parts by using a 11/15 or 12/16 Ti Parts Workshop

Does these parts are compatible
Hi there,

Yes you could use the 12/16t sprockets as a replacement for your bicycle.

Can it use as 3speed sprocket??
19 Jan 2018
i want to change 3speed sprocket
Hi there,

It is likely you are using a BSR hub meaning these will not fit, the BSR is designed for sprockets with 3 splines rather than 12 splines.
If you are using the BWR 6 speed hub then you could use one of these sprockets.

Is there a steel alternative to these?

If this is for a Brompton please look at - SJS Cycles part number : 13766
