Hans device mandatory from 2016

[gadget]

if you send your smelly helmets down to the Norfolk Pikey's old shed, I'm sure we can drill them out and put in a threaded insert.
just tell me what size thread you want and it will look just as good as a factory fit.
not only that, it will be guaranteed until you get to the first scrutineering at Oulten park. as a bonus free of charge, we will tea bag them for you ready for the new season.

happy new peeps and look forward to seeing you all in the new year.
