Width and standard freehubs
24 Aug 2020
Hello, team!
Could you tell me two things?
1. How wide is this sprocket(in mm)?
2. Will it fit on standard freehub(like hope)?

Hello, Yes this will fit onto Shimano hyperglide style freehubs. With regards to the width, I've measured the 12t one at 3.6mm thick

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??
19 May 2018
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
