I think you're wrong.
3 years ago, the price would have been £37.50 to the USA but to Finland it was £45. It is now £37.50 for Finland so why are you a loser?
Next, the crank should be good for season after season and not 'one race'. Importing parts to Finland you would likely pay the same 20% as "import duty" as you paid when it was VAT of 20%. But it depends what the invoice says. If you get £800 of parts for a declared value of £400 you will only pay £80 in tax and not the £160 I charged in VAT 3 years ago.
