Modular helmets... trying not to be cynical.
I just took my Caberg (remember them from about 8 years ago?) modular completely apart to give it a revamp, and discovered that one of the plastic posts inside the shell was broken. So, ordered a $600 Shoei Neotec, and discovered that the Shoei is basically constructed the same way--little Phillips head screws in plastic posts! Ah me.... sent the Shoei back to the dealer. Then improved the Caberg's fit by adding self-adhesive polyurethane foam to the EPS liner and fixed its broken post with a 4-40 countersunk screw. Discovered the chin-bar up-latch, which is a metal ball rubbing against the plastic chin bar near the pivot, is just wearing out. I expect it will last for another year or two and then not up-latch at all. Also discovered the Caberg shield (no scratches) had TINY BUBBLES INSIDE THE PLASTIC! Sent Caberg photos. They said the shield is past its useful life. Ordered a new shield from England.
Thoughts: Helmets, especially the modulars with all of their moving parts, are disposable, limited-life objects. Unless one is lucky enough to have a dealer who carries the replacement headliner, chin bar, etc., in order to replace all of their worn parts, they simply wear out. They are, in fact, designed to wear out. When buying a super-deluxe, extra-pricey modular helmet, that is something to keep in mind.
My next helmet will not be one of the expensive ones. It will be a name-brand, but less expensive, modular.
