Time trial helmet sizing????
 

Hey, so I'm looking at upgrading to a aero helmet for triathlons but can't decide on size. I'm looking at the Louis garneau vorrtice helmet but unfortunately none of my local bike shops carry it nor any other time trial helmets for me to try on. They can only order it for me but that really doesn't help......

I seem to be between medium and large and need help. The fit chart for the helmet is as follows S(53-56cm; 20.5-22.0in)/ M(56-59cm; 22-23.25in)/ L(59-62cm; 23.25-24.375in). I've measured my head several times and depending on how tight I pull the tape, I get between 22.75 in (when really tight) to 23 inches. Anyone have any experience with this helmet and its fit since I'm on the upper end of medium. I understand that other LG helmets have the same fit so does anyone have experience with those?
...If it helps, I have a cheapo giro rift helmet which is universal adult (it runs small though) and I'm less than a spin of the roc-lock from being to small. Also, in high school, (2yrs ago I'm only 20 in college) I always wore a large schutt dna helmet.

I am almost the same size....22.5 to 22.75.... had the same concerns. Just yesterday my Medium Size LG Chrono-Leggera was delivered. It fits with room to spare. I rode the trainer this AM without the visor.

I'd recommend a Medium. If I'm wrong, send it back and exchange. This place http://www.onetri.com/bike-helmets-c...06ccfa3a9debfc had great service.
