Which Bell size am I?
Measure your head first (tape or string around the widest part, 1-2 cm above the eyebrows), then read it off the table above — Bell sizing is not the same as the next brand's. Across the range, Bell covers 50 to 65 cm (19.7 to 25.6 in). If your measurement falls outside that, no Bell helmet we track will fit you.

None of these Bell models has been rated by the Virginia Tech Helmet Lab yet. That is not a safety verdict: it just means the lab has not bought and tested them. Every helmet here still meets its market's legal standard (EN 1078 in Europe, CPSC in the US).
