Local bike parts dealer told me months ago that he had bought up a large amount of tyres, oil, parts etc early in the year as the suppliers had given him the wink that there would be shortages due to Covid and Br*xit based Customs issues .
Similarly talking to a local Givi dealer (largest independent in UK if not Europe) who exports to Europe and is having loads of grief with Customs within the EU despite his paperwork being correct ...so Br*xit based sh*t.
When I was trying to get some new bike gear for my wife a couple of months ago even the larger outlets Infinity , J and S , M and P, Get Geared and Sportsbikeshop all said they were really struggling to get European kit again due to Covid production issues and the dreaded Br*xit import and Customs issues
