This is a great helmet. My head was measured at 56cm (no play), slightly oval, i.e small.
First try and I was ready to return it ; the bloody thing was tight. Heard the T2 has a snug race fit, so I decided to give it a try. After 2 weeks, it slides on nicely, and is comfortable; if you do not want the sung fit, then go a size up, (add extra cm or 2 to your measurement) The flow into the helmet is great, and no whizzing or stuff like that.
