What's the stack height of this?
By

Hi

What's the overall stack height of this compared to a Brompton one?

I ask as I have a JK one installed on my 2015 M6L (steel forks) and have the issue that there are only 3 or 4 threads of the threaded forks' column/stem engaged with the top locknut, which suggests the stack height is greater.

Thanks
Hi there,

The stack height is approximately 48mm.

Thanks.
What's included?

Hi

Does this headset kit include everything needed to replace the Brompton headset i.e. absolutely everything top and bottom of the head tube, including seals?

Presumably you need to prise off the Brompton bearing races/cups in order to replace with the JK cartridge bearing? If so, is this a difficult job?

And what size spanners are needed for the nut and locknut, please?

Thanks
Yes, the complete headset, as pictured, is included.

The lock nuts are for 36mm spanners and yes you would need to remove the stock cups and crown race. - very easy if you have the correct tools / knowledge/experience.

Coming loose every few days
By

Hi,

I've bought this and had it fitted a few months back by Evans on a Golden Brompton Service, but I need to tighten it every few days and always find myself taking the headset wrenches with me... is this possibly because of a defective headset, or was it a wrong fitting from the very beginning? Would you be able to advise? I think it's quite dangerous to have it come loose all the time.

Thanks
Hi there,

This sounds like it has not been fitted properly, the two nuts need to be locked off against each other properly.

Why won’t it fit the titanium forks and is it lighter than the standard unit?
By
30 Apr 2019
The lower section fouls / binds on the steerer tube. Yes it is lighter, we recommend using SJS Cycles part number : 35038

Thanks - 30/04/19
Can it be used on any Brompton?
By

Apart from Ti fork, I've read that. Thanks
Yes, we have fitted to many Bromptons including staff bikes!
