I bought this last week but stupidly bought the wrong size! It's a medium 54-58cm. I thought it might be OK as I was just over 58cm but unfortunately it's uncomfortable. It's been used once for 20 miles so is as new with all packaging.
If I sell this I'll get a new one in the right size as it's a cracking helmet in terms of design, looks and breathability. See http://www.wiggle.co.uk/met-dimension-data-rivale-aero-road-helmet-black... for more info and reviews.
