Can these mount Specialties TA X110 chainrings to DA 9000 crank
26 Mar 2022
Can I use these to mount chainrings to a Shimano DA crank? (I realise there will be no decorative cover to smooth out the aesthetic of the arms)
We have not tested this so cannot confrim.

What length is the male thread part?
22 Oct 2021
Thank you for your enquiry, it is 6.5mm

Would this fit a Brompton ?

It seems Brompton use M8X6.5mm, so what are the dimensions of those ?

No, as Brompton chainrings have one bolt that threads into the back of the crank arm- so we only advise using original Brompton chainring bolts.

Can you also deliver the long version of the Middleburn Bolts for Single Rings?

Hi there,

We do not have any longer version for single rings but we do have double/triple bolts that are longer and should do the same job.
