I got to work this morning and through a small comedy of errors managed to drop my helmet onto a concrete floor from the height of a tabletop... There's a small crack in the Polestyrene bit right at the front, but no damage to the shell. Its only visible to the eye if I flex the helmet with my hands. But its still compromised.

I'm thinking I'm gonna have to replace it right?

Whaddya reckon folks?
