There were several threads on sizing these helmets when they first came out with many people saying they run small. After reading a bunch of '18-'19 threads on this, it is not clear to me whether this is more of a head shape issue than sizing?
Is going up one size still the general recommendation when ordering online?
Fwiw i currently have and am ready to replace a M size Lynx and measure exactly 22" (56 cm). I should be a perfect 6 7/8, and i believe my prior sized helmets were that size, but i have been using only dial fits for ages…
