I Found the Smith Holt W/ Audio for a steal online but the only size they have is small, I'm 16 and measured as best as i could and got 55cm.. the small says it's made for about 54-56 cm, but i'm a little cautious about buying it and having it be too small, does anyone know how adjustable helmets usually are? Will i be safe ordering a small?
I have a Smith Variant and it has a lot of room for adjustment. Best thing to do is to go to a shop that sells them, try all the different helmets and their sizes, see which one you like and fits you best and shop for those online. Or do your job to support the economy and buy from the local store.
