........ Part of the retention system on my old Bell lid has snapped with age (brittle plastic) so it's time for a new one. Spent a 'massive' £15.........
Oddly enough my Bell had to go in the bin a few months back for exactly the same reason. Wasn't really old enough to need replacing, and I was annoyed that new internal webbing wasn't available for the model that I owned. Crappy plastic used by Bell maybe?
