The joys of Brexit there! You think that's bad tho, I have a German-market vehicle (cause LHD) in the UK currently that obviously uses some parts that need to come from the EU, and I'm also bringing my truck over from the US so yeah, fun times to be had with customs
Someone brought up the question why not use DH-intended BB and cranks. I might have missed your answer there - are you focusing on the Profile etc. bits just for their looks on your bike? Like, the common DH stuff just don't flow with it?
