Does anyone know the thread pitch for the rear bolt that afixes to the hanger and then the rear ta to it. I want to replace the one I have. Can't seem to find replacement details easily. If anyone has a link to a replacement one I could buy. Please.

Am I missing something here.

I have lower bearing bevel up and the upper bearing bevel down. Then when I put the fork thru along with other two components. There is a small gap. As as shown in the image.
I just want to make sure I am not missing something. I did wonder if the two bearings are different sizes.

Thank you for any help.

Hi. I'm planning 105 di2 shifters , disc brakes and front/rear derailleurs. Id like to lower weight by using carbon crankset, chainrings and cassette.

Could you recommend a Chinesse options with some longer term reviews. I was thinking leese crankset but does that require an adapter for chainrings then ? And possibly a ztto cassette. But again concerned about material choice here . Aluminium v steel etc. and then I need to consider chain line but I know nothing about this.

Any advice welcome thank you
