• Hi all,

    trying to assess whether ive got incompatible threads on my lockring/hub and whether ive bought the wrong sprocket, any help would be hugely appreciated.

    Recently snagged a set of H+Son rims laced to some Brick Lane Bikes hubs (https://www.bricklanebikes.co.uk/blb-track-rear-hub-silver).

    I picked up a miche track spocket

    and a surly lockring:

    Last night i popped the sprocket on no problem (only to finger tight) and then offered up the lockring on the smaller thread, it threads pretty easily across the first 1-2 threads then starts to get stiffer (not cross threading), im loathed to put anything more than finger strength into tightening it at the moment in case ive got the wrong collection of bits here. Surly do say their threads can be a little stiff and can change the angle of the hub threads, but i was under the impression this only relates to their sprockets.

    Apologies in advance if this is a real virgin question but im desperate to get my new build rolling!
